Event
The Event tab is available on activities that expect an incoming event. These are activities that wait for an incoming event in a process. These activities cause the process instance to suspend until the incoming event is received. An Event tab has the following fields:
Field |
Description |
Candidate Event Key |
Expression used to evaluate whether the incoming message is appropriate for this process. This expression is specified in XPath, and only data from the incoming event is available for use in this XPath expression. For more information about XPath expressions, see XPath. |
Event Timeout (msec) |
The amount of time a message will wait (in milliseconds) if it is received before this task is reached in the process. If the event timeout expires, an error is logged and the event is discarded. If no value is specified in this field, the message waits indefinitely. If zero is specified, the event is discarded immediately, unless this has already been reached. |
The following illustrates the Event tab.
The following table describes the available activities with Event tabs. For more information about tasks that have Event tabs, see the section for the palette you are interested in.
