Known Limitations

This section describes known limitations in the current release of StreamBase LiveView Data Mart and TIBCO StreamBase LiveView Desktop.. Each item includes a tracking number, description, and whenever possible, one or more workarounds.

CQS‑1769 Time predicate expressions cannot contain today().
Description The time predicate for time-windowed queries cannot parse today().
Workaround Use now() or an equivalent time predicate.
CQS‑1692 Referencing a JDBC table that has not been properly loaded prevents LiveView Server from starting.
Description JDBC tables are not automatically started as part of a LiveView Server project start. This means that if you configure a project with a JDBC table, you need to load the database before starting LiveView Server.
Workaround Load the JDBC database before starting LiveView Server.
CQS‑1690 Apple Java 1.6 implementation must be installed on MacOS X platforms.
Description StreamBase applications that are based on Eclipse 3.8, such as Studio 7.3.x, LiveView Desktop 1.3 and 1.4, and LiveView Workspace Manager 1.4 will use Java 1.7 if it is present, in preference to Java 1.6. Normally, this is fine, but LiveView Desktop uses a charting module that requires Java 1.6 on the Mac OS X platform.
Workaround Ensure you have Java 1.6 installed for MacOS X in the default location: 
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
CQS‑1614 LiveView WebUI fonts and kerning do not load properly.
Description The line spacing and dynamic table sizing on the WebUI do not render correctly on the initial page load.
Workaround Reload the browser and manually readjust the font sizes.
CQS‑1202 Aggregate function may not use the multithreading setup of the base table.
Description The aggregate functions Avg, Max, Min, Stdev, and Stdevp do not currently take advantage of any multithreading setup from the source table
Workaround None at this time.
CQS‑1114 LiveView 1.2 sample projects do not appear in File → Load StreamBase Sample listing.
Description The file that created the list of sample projects was not updated for LiveView 1.2.
Workaround

Import the sample using the File → Import menu.

  1. Start StreamBase Studio.

  2. Select File → Import from Studio's top-level menu.

  3. In the General category, select Existing Projects into Workspace and click Next.

  4. In the next panel, use the Browse button beside the Select root directory field.

  5. Navigate to your StreamBase CEP installation directory, then to its liveview\sample\lv-sample-samplename folder. For example, on 64-bit Windows 7, navigate to the following path (shown on two lines for publication clarity): 

    C:\Program Files (x86)\StreamBase Systems\StreamBase.7.2\
 liveview\sample\lv-sample-samplename

  6. Make sure the Copy projects into workspace check box is checked.
