The engine must report error/warning when invalid events are triggered ----------------------------------------------------------------------
Key: SCXML-22 URL: http://issues.apache.org/jira/browse/SCXML-22 Project: Commons SCXML Issue Type: Improvement Affects Versions: 0.5 Environment: Win XP Professional, jdk 1.4.02 Reporter: Raj Rao The semantics must report an error/warning/notification when an invalid event is triggered, instead of silently discarding it. An invalid event is one that is not specified for the current state. Here's an excerpt of a converstaion, where the suggested workaround was not applicable. This requirement is crucial for me. -- Raj -------------------------------------------------------------------------------------------------------------------------------------- > Hello, > > I tried sending an invalid event to the state machine > and didn't see any error being reported.

One of the ways you could track this is to register a SCXMLListener on the executor and track onTransition() callbacks (if you get none, the trigger is "invalid" -- per your definition above). -Rahul -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
