Starting process from a signal : multiple deployments

magnayn — Thu, 03 Apr 2014 16:02:06 GMT

Hi!I have a process definition, which is using the new signal event definition to trigger (5.15.1) the creation of a process instance. I.E: <startEvent id="startevent1" name="Start"> <signalEventDefinition id="start1" signalRef="theSignal"></signalEventDefinition>

This sounds quite logical because you may want to start multiple processes based on a single event - this is quite handy in service orchestration where external systems can simply report to the workflow engine and return to doing their business.

In your case, you can probably version your events to prevent multiple ones from being executed, or rename event names on old versions.

This is an issue, since a signal start event should only trigger the latest version of a process definition. We'll look into it.

Best regards,

Thanks - I did some digging myself and I also think it's a bug. I raised a ticket for it
http://jira.codehaus.org/browse/ACT-1978

It looks to me like a relatively simple fix.
