Fixed in Live Datamart 1.6.5

TIBCO Live Datamart 1.6.5 is a service pack release, correcting the following issues. Live Datamart 1.6.5 inherits all fixes on the 1.5.x release branch through 1.5.7.

Number	Resolution
CQS‑3118	In previous releases, for tables configured with periodic publish, if a row was added then removed within the publish period, clients would see a delete event for a row that was never added. This was corrected for releases 1.6.5 and 2.0.4.
CQS‑3115	In previous releases, join target tables that had the snapshot-parallelism attribute set greater than 1 would prevent LiveView server from completing startup. This was fixed for releases 1.6.5 and 2.0.4.
CQS‑3074	Predicates that contained index key fields set to null would sometimes return an error. The cause was identified and corrected in releases 1.6.5 and 2.0.3. A workaround for earlier releases is to set the system property `liveview.query.unique.plans` to 1.
CQS‑3072	For dynamic aggregation queries only, and only the continuous portion thereof, and only for predicates that are planned where there is more than one value used for index equity, client data updates could be missed. The way to tell whether a predicate has more than one index equity is by looking in the server log for instances of `Predicate rewritten: <re-written predicate> plans: X, unique plans: Y`. If Y is greater than 1, then this issue can occur. This situation was corrected in LiveView 1.6.5 and 2.0.3. For LiveView 1.6.4 and below, and for 2.0.0 through 2.0.2, you can work around this issue by setting the system property `liveview.query.unique.plans` to 1. LiveView 1.5.x did not have the problem.

Fixed in Live Datamart 1.6.4

TIBCO Live Datamart 1.6.4 is a service pack release with updates and enhancements. The following issues were corrected in this release. Live Datamart 1.6.4 inherits all fixes on the 1.5.x release branch through 1.5.7.

Number	Resolution
CQS‑2930	LiveView Server startup time was substantially improved when starting a configuration that has already run at least once, and has no configuration changes.
CQS‑2871	In LiveView Desktop 1.6.3, trying to re-open a configured table action failed when the selected row contained a colon anywhere, including in timestamp fields. This occurred when the Open new view View Settings option was selected, which is the default setting. The cause was identified and corrected.
CQS-2847	If a table index was defined as case insensitive, and a query predicate was planned to use that index, and the index matching string value contained a close-parenthesis character, then the continuous portion of query would not return results when it should. This was fixed. Note that the snapshot portion of the query is always correct.

Fixed in LiveView 1.6.3

TIBCO LiveView® 1.6.3 is a service pack release with updates and enhancements. The following issues were corrected in this release. LiveView 1.6.3 inherits all fixes on the 1.5.x release branch through 1.5.7.

Number	Resolution
CQS‑2576	In previous releases, the lv-client command accepted a URI as the argument to its `-u` option, but did not recognize options appended to the URI with standard question-mark syntax. Starting with release 1.6.3, lv-client accepts the full URI syntax including options. For example: lv-client -u lv://lvserver:10090?client-info=StatusMonitor
CQS‑2557	The names of spaces in TIBCO ActiveSpaces can contain characters that are not valid StreamBase characters. In previous releases, such spaces could not be used with LiveView. Starting with this release, LiveView detects invalid characters in ActiveSpaces space names and converts each to an underscore. This allows such spaces to be used with LiveView, but with converted names.

Fixed in LiveView 1.6.2

TIBCO LiveView® 1.6.2 is a service pack release with new features and enhancements. The following issues were corrected in this release. LiveView 1.6.2 inherits all fixes on the 1.5.x release branch through 1.5.7.

Number	Resolution
CQS‑2553	In previous releases, the LiveView Delete adapter would accept a predicate with a limit specifier, but the limit was ignored. This is now fixed such that a delete predicate with no limit specifier means there is no limit to the number of rows deleted, and a predicate with a `limit n` specifier will delete from zero to no more than `n` rows.
CQS‑2531	In some cases, LiveView 1.6.0 clients connecting to a LiveView 1.6.1 server did not receive remove events. The cause was identified and corrected such that all 1.6.x clients are expected to interoperate with any 1.6.x server.
CQS‑2522	In previous releases of LiveView Desktop, when you selected columns and rows in a grid view and copied them to another program such as Microsoft Excel, the copied column order would remain in the underlying LiveView table's column order. This was corrected so that grid copies now preserve the current, visible column order in LiveView Desktop.
CQS‑2480	In previous releases, if the StreamBase and LiveView server ports were incorrectly configured to be the same, the StreamBase server would fail to start with a confusing error message. The error message was clarified.
CQS‑2398	In previous releases, if you used the Select button in LiveView Desktop's Connect to LiveView dialog to select a downloadable workspace, the resulting Desktop perspectives could incorrectly overlap. The cause was identified and corrected.
CQS‑2275	LiveView Desktop sometimes showed a black background behind DataWatch (Panopticon) charts. This release includes updated DataWatch libraries that resolve those issues.

Fixed in LiveView 1.6.1

LiveView 1.6.1 is a service pack release with new features and enhancements.

Number	Resolution
CQS‑2196	In some cases, the .NET API would not correctly read a URI that passed in parameters. This was fixed.
CQS‑2242	An aggregate table that used the expression Max(timestamp) would fail. This was fixed.
CQS‑2394	In certain rare conditions, LiveView tables with snapshot-parallelism greater than one might drop a snapshot add event. A run-time exception warning is written to the server log, but the client gets no notification. (Continuous queries do not have this issue.) This was fixed.
CQS‑2422	Queries of type snapshot and continuous with query predicates that have index equality terms on more then one index that were issued against tables with multiple secondary indices could miss continuous data updates. (The snapshot portion of the query is always correct.) This was fixed.

Fixed in LiveView 1.6.0

LiveView 1.6 is a minor release with new features and enhancements.

Number	Resolution
CQS‑2320	In LiveView Desktop, some grid view query formatting, such as column reordering, hiding, or width adjustments, would be removed if the query was edited or refreshed. This was fixed.
CQS‑2273	In the Java API, if query listeners threw unhandled exceptions while processing events provided to them by LiveView's API, the server connection closed. This behaviour was changed. Now, the query listener receives the exception thrown via #getExceptionRaised, the query is closed, but the connection is unaffected.

Fixed in LiveView 1.5.7

StreamBase LiveView 1.5.7 is a maintenance release.

Number	Resolution
CQS‑2482	Continuous queries against tables with more than 100 fields where moderate to high data rates were delivered to clients showed poor performance. This was fixed.
CQS‑2422	Queries of type snapshot and continuous with query predicates that have index equality terms on more then one index that were issued against tables with multiple secondary indices could miss continuous data updates. (The snapshot portion of the query is always correct.) This was fixed.

Fixed in LiveView 1.5.6

LiveView 1.5.6 is a maintenance release.

Number	Resolution
CQS‑2153	The snapshot portion of a snapshot and continuous dynamic aggregation query could return incorrect results when the LiveView table was very large (on order of a million rows) and had snapshot-parallelism enabled. Subsequent continuous updates were correct and snapshot-only queries were always correct. This was fixed; snapshot and continuous aggregation queries against very large tables with snapshot-parallelism enabled now return correct results.
CQS‑2152	Dynamic aggregation queries that had a continuous portion did not remove all state from the system when the query was closed, which sometimes caused heap accretion over time. This was fixed.
CQS‑2095	When starting LiveView server from the command line, the --liveview-port option to set a non-default LiveView server port was accepted but ignored, and the default port (10080) was always used. This was fixed.
CQS‑2052	Update rules that specified the _ArrivalTime could overwrite a tuple's timestamp field, causing issues with queries that used the ordering of tuples by arrival time. This behavior was changed. There are three allowed actions for time-order violation, based upon the configuration of the liveview.updateRule.onTimeOrderViolation field: liveview.updateRule.onTimeOrderViolation=KeepTuple (default): The tuple passes through unchanged and logged as a WARN message. liveview.updateRule.onTimeOrderViolation=DropTuple:The tuple is dropped and logged as a WARN message liveview.updateRule.onTimeOrderViolation=CorrectTuple: The tuple is corrected by using the old time stamp and logged as a WARN message.
CQS‑1889	The Saved Query functionality in LiveView Desktop did not save charting views to the Recent Queries node. This was fixed.

Fixed in LiveView 1.5.5

LiveView 1.5.5 is a maintenance release.

Number	Resolution
CQS‑2092	In previous releases of the LiveView .NET client, when a tuple was removed from a query result, the tuple id was returned. This was changed; the id and and contents of the removed tuple are now returned when a tuple is removed from a query result.
CQS‑2050	In previous releases, LiveView server would accept top-N queries that were of type CONTINUOUS only. This was changed; top-N queries that are CONTINUOUS only are now rejected with an error. Use SNAPSHOT_AND_CONTINUOUS for the query type when using top-N queries.

Fixed in LiveView 1.5.4

LiveView 1.5.4 is a maintenance release.

Number	Resolution
CQS‑1994	Certain complex query predicates caused mis-registering of continuous query plans, which could result in some continuous queries not delivering all the expected rows. This was fixed.
CQS‑1335	If a LiveView data table had large queue backups, clients would register and unregister a query before the query actually started. In previous releases, the query was then executed, even though no output was ever sent to the client. In the current release, such queries do not execute.

Fixed in LiveView 1.5.3

LiveView 1.5.3 is a maintenance release.

Number	Resolution
CQS‑1928	Under some conditions where a table row was deleted from a source table or the data rate for the source table was very high, static aggregation of averages could return NaN. This was fixed.
CQS‑1925	Panopticon Designer sometimes did not correctly parse LiveView Desktop query predicates if there was a previously configured Panopticon Workbook setting. This was changed so that a query predicate sent from LiveView Desktop always overrides the Panopticon Workbook settings.

Fixed in LiveView 1.5.2

LiveView 1.5.2 is a maintenance release.

Number	Resolution
CQS‑1878	Under some conditions, Panopticon Workbooks did not load and LiveView returned the error message `Interval must be > 0`. This was fixed.
CQS‑1845	Dynamic aggregation results could be miscalculated when rows leaving the query scope also changed groups. This was fixed.

Fixed in LiveView 1.5.1

Number	Resolution
CQS‑1837	Valid queries that failed to compile sometimes caused excessive error logging. This was fixed.
CQS‑1835	Queries with aggregate functions could return incorrect aggregate results if the query predicate caused rows to leave scope. This was fixed.

Fixed in LiveView 1.5.0

Number	Resolution
CQS‑1739	The QueryParser did not accept quoted strings that contained reserved words or certain special characters. This was fixed. A quoted string as delimited by the outermost set of single or double quotes may now contain reserved words. In addition, unpaired quotes, such as apostrophes, may now be used inside a double-quoted string, or double quotes may now be used inside a single-quoted string.

Fixed in LiveView 1.4.6

Number	Resolution
CQS‑1902	In previous releases, when an alert was configured with a time delay, if the alert conditions remained true for longer than the configured time delay LiveView Server would sometimes incorrectly fire alert actions for each instance of the time delay elapsed. This was fixed.

Fixed in LiveView 1.4.5

Number	Resolution
CQS‑1847	In previous releases, when an embedded publisher recovered data from a persisted table, the end the recovery process was not clearly marked. Now, when recovery is complete, an end-of-set tuple (called a punctuation tuple) is emitted from the data stream TheLastGoodRecordIn. See Persistence and Recovery for more information about using persisted data with embedded publishers.

Fixed in LiveView 1.4.4

Number	Resolution
CQS‑1786	Certain complex queries with multiple nested AND and OR terms could result in long query planning time. This was fixed.

Fixed in LiveView 1.4.3

Number	Resolution
CQS‑1784	Certain patterns of querying that used dynamic aggregation (an undocumented feature not used in most deployments) could exhaust JVM PermGen space in the LiveView server. This was fixed.

Fixed in LiveView 1.4.2

Number	Resolution
CQS‑1773	Under some circumstances, if a query used dynamic aggregation (not a fully documented and supported feature in LiveView 1.4) and the query was unsubscribed, the query results would continue returning even though the query was no longer executing. This was fixed.
SB‑24708	LiveView Server sometimes emitted a large number of log messages for queries with many disjunctive clauses. This was fixed.

Fixed in LiveView 1.4.1

Number	Resolution
CQS‑1741	LiveView 1.4 startup sometimes reached the 64kB limit for some projects. This was fixed.
CQS‑1712	When using the .NET API, LiveView previously threw an exception if a timeout occurred while a LiveView connection attempted to dequeue data from a LiveView Server. This was fixed. Instead, a ConnectionConfig.ConnectionEvent is fired with an EventType of ConnectionEventArgs.ConnectionEventType.CONNECTION_LOST. Upon receiving this event, an application regards the connection as no longer valid and a new LiveViewConnection is created.
CQS‑1699	Continuous queries that used CQSInternalID in the predicate incorrectly threw an error. This was fixed.
CQS‑1668	Sometimes exceptions happened when LiveView Server was launched with table-level update rules. This was fixed.

Fixed in LiveView 1.4.0

Number	Resolution
CQS‑1681	In previous releases, deletion of rows in LiveView tables did not also delete corresponding rows in ID chaining tables. This was changed; rows in ID chaining tables are now deleted. Deletions should be performed only when the affected rows are quiescent; simultaneous deletions and updates may result in inconsistent data.
CQS‑1662	A configured data source application for a LiveView data table could sometimes publish data before the connection to the table was ready. This could result in some data being dropped. This was fixed.
CQS‑1633	In some cases, the Publish Alert dialog would render table field names incorrectly. This was fixed.
CQS‑1625	In some cases, if a LiveView project contained a StreamSQL application with comments the project would fail to compile. This was fixed.
CQS‑1457	LiveView projects with applications that used the StreamBase Thomson Reuters TREP-RT adapter would sometime fail to start correctly. This was fixed.
CQS‑598	You cannot use insert-rule and update-rule in fields that are declared a primary key. In some cases, doing this did not immediately throw an error. This was fixed; if you try to use an insert-rule or an update-rule on a field that is designated a primary key, LiveView throws an error.

Fixed in LiveView 1.3.7

Number	Resolution
CQS‑1730	Tables with conflation configured via the publish-interval-millis attribute sometimes published data in the incorrect state to a client if the client query was delayed. This was fixed.
CQS‑1712	When using the .NET API, LiveView previously threw an exception if a timeout occurred while a LiveView connection attempted to dequeue data from a LiveView Server. This was fixed. Instead, a ConnectionConfig.ConnectionEvent is fired with an EventType of ConnectionEventArgs.ConnectionEventType.CONNECTION_LOST. Upon receiving this event, an application regards the connection as no longer valid and a new LiveViewConnection is created.
CQS‑1699	Continuous queries that used CQSInternalID in the predicate incorrectly threw an error. This was fixed.
CQS‑1668	Sometimes exceptions happened when LiveView Server was launched with table-level update rules. This was fixed.
CQS‑1651	Certain configurations of aggregate tables with multiple data sources caused LiveView Server startup to fail with a compilation error. This was fixed.
SB‑24708	LiveView Server sometimes emitted a large number of log messages for queries with many disjunctive clauses. This was fixed.

Fixed in LiveView 1.3.6

Number	Resolution
CQS‑1642	In some cases, LiveView Server could not use the Azul Zing JVM. This was fixed.

Fixed in LiveView 1.3.5

LiveView 1.3.5 is a maintenance release with feature enhancements only. See New Features and Updates in LiveView 1.3.5.

Fixed in LiveView 1.3.4

Number	Resolution
CQS‑1626	Special cases of advanced aggregations did not handle null values. This was fixed.
CQS‑1622	The documentation for Running LiveView Server as a Windows Service used the wrong name for the Hello LiveView sample project directory. The correct name for the directory is lv-sample-helloliveview. This was fixed in the documentation.

Fixed in LiveView 1.3.3

Number	Resolution
CQS‑1607	Certain advanced aggregations did not correctly handle null values. This was fixed.
CQS‑1408	LiveView Server did not correctly report sequence numbers to publishers if the table configuration file had the publish-interval-millis tag set. This was fixed.

Fixed in LiveView 1.3.2

Number	Resolution
CQS‑1472	The MaxRecordsLimit value caused dynamic aggregation results to be truncated based on the number of parallel regions. This was fixed.
CQS‑1445	In some cases, actions executed from a timeseries graph would not run. This was fixed.
CQS‑1408	LiveView Server did not correctly report sequence numbers to publishers if the table configuration file had the `publish-interval-millis` tag set. This was fixed.

Fixed in LiveView 1.3.1

Number	Resolution
CQS‑1347	Persisted data was sometimes not republished during recovery. This caused incorrect aggregate results after recovery. This was fixed.

Fixed in LiveView 1.3.0

Number	Resolution
CQS‑1240	When the LiveView Server was shutdown, the .NET Client API would generate an unhandled exception. This was fixed.
CQS‑1163	When the .NET Client API lost its connection to a running LiveView Server, the client instance would crash. This was fixed.
CQS‑1035	In previous releases, if you tried to start LiveView Server on a port that already had an SBD process running, the launch would fail without a clear error message and kill the SBD process. Now, the launch will exit gracefully with a "Port already in use" error and the extant SBD process will keep running.
CQS‑612	LiveView Server would sometimes send the message `All tables have been loaded. LiveView is ready to accept client connections` before all of the project containers were running. This was fixed.
CQS‑407	If there was a schema mismatch between client and server in a dynamic aggregation query, LiveView Server would fail to send error messages to the client. This was fixed.
CQS‑279	A SNAPSHOT query with many parameters being evaluated against an IN operator would run too slowly. This was fixed.

Fixed in LiveView 1.2.2

Number	Resolution
CQS‑1147	LiveView 1.2.2 Desktop now uses dictionary sort order for table grid-view sorting. In previous versions of LiveView, if you performed an ascending sort on a string field, you would see "AT&T" before "Abbot." In LiveView 1.2.2 the same sort will return "Abbot" before "AT&T."
CQS‑1145	The `avg` function, when applied to a field with a nonstring group key, sometimes produced an incorrect result. This was fixed.
CQS‑1138	SNAPSHOT_AND_CONTINUOUS queries to tables configured for periodic publishing sometimes had multiple copies of the same updates in the snapshot and continuous results. This was fixed.

Fixed in LiveView 1.2.0

Number	Resolution
CQS‑638	In previous LiveView releases, multiple tables in the same LiveView instance could not share configured alert rules. You can now also share an alert rule configuration across multiple tables in the same LiveView instance or across multiple LiveView instances. Contact StreamBase Systems Technical Support for further information.
CQS‑575	The .NET class `LiveViewConnectionFactory` now has a new method, `GetBackgroundConnection()`, which allows you to spawn a background task that keeps retrying connections until successful. This functionality is implemented using a subclass of `System.ComponentModel.BackgroundWorker` for convenience.
CQS‑598	In previous LiveView releases generated project files were always saved to the `lv-bin` directory in the main project folder. You can now specify where generated project files are saved. Contact StreamBase Systems Technical Support for further information.
CQS‑445	You can use the new CQSDataUpdatePredicate field of a preprocessor's DataIn stream to update multiple rows of a table based on a query predicate.
CQS‑392	If the connection from LiveView Desktop to LiveView Server was lost, the File → Connect to Server option did not re-enable. This was fixed.

Fixed in LiveView 1.1.3

Number	Resolution
CQS‑760	When a table was configured as the source for multiple levels of aggregation and a null value for an aggregation key was published to the source table, the null value was sometimes not propagated correctly to all levels of aggregation. This was fixed.

Fixed in LiveView 1.1.2

Number	Resolution
CQS‑764	LiveView queries that used StreamBase Expression Language functions and features did not return rows or returned syntax errors. This was fixed.

Fixed in LiveView 1.1.1

Number	Resolution
CQS‑688	Some out-of-scope messages were not being issued consistently. This was fixed.
CQS‑678	Customers may create tables with more fields than they could in previous LiveView releases.
CQS‑662	Some aggregation queries returned incorrect results. This was fixed.
CQS‑658	Some queries that used IN or OR against an indexed table field did not correctly match all field values. This was fixed.
CQS‑657	LiveView would sometimes not correctly compile tables in the LiveView sample projects. This was fixed.
CQS‑656	Some queries against multi-key fields returned incorrect results. This was fixed.

Fixed in LiveView 1.1.0

Number	Resolution
CQS‑622	When a record was deleted, the signal to delete the record could be sent to a client whose query predicate the record does not satisfy. This issue was fixed.
CQS‑595	Queries that used the less-than-or-equal-to operator (`<=`) were not returning expected results. The cause was identified and corrected.
CQS‑594	Under some circumstances, the results of a continuous query could include an incorrect deletion of a record; in client views, the record was incorrectly deleted or, after an update, contained a subset of the field values. This issue was fixed.
CQS‑561	When a row update to a data table changed the value of a field used to group rows in a downstream aggregation table, live queries on that aggregation table could receive an extra deletion event from the server. That event included a reference to a nonexistent (null) tuple. This was corrected.
CQS‑541	Background images for the Workbook Viewer in LiveView Desktop were failing to display. This was corrected by updating to Panopticon version 5.10.
CQS‑528	When a new record and its first update arrived into an aggregation table in the same publishing cycle, the LiveView conflation mechanism was causing an incorrect update to LiveView clients. Re-querying the data by restarting LiveView Desktop or using a snapshot query showed the correct results. This issue was fixed.
CQS‑440	In previous releases of LiveView Desktop, if you configured a default column set for a table, then started a query from a right-click action, the default column set failed to apply. This was corrected.
CQS‑162	The LiveView IN function with over 1000 parameters was throwing a ClassFormatError, or was processing slowly. The cause was identified and corrected in StreamBase 7.2.5.
