Parallel Event Gateway with User Task Ignores All Signals

elic — Wed, 28 Sep 2016 20:08:11 GMT

We have a process designed to implement Pause-Resume-Abort but there's an issue when the process reaches a User Task from a parallel event gateway. We'd like to be able to signal the "Complete" intermediate signal catching event while the process is sitting in the "Resume?" user task, but when we se

Looking at your process diagram, i is modelled such that the process instance starts, then pauses until either a "pause" or "complete" signal is received (this is the event gateway). The only way the "resume" task can be reached is after a "pause" signal is received.

This is a somewhat confusing pattern since a user task (Resume in your case) is an implicit wait state so I'm not certain as to the purpose of the "Pause" event.

Either way, you can simply add a boundary catch event to your "Resume" task to act on the "Complete" signal.
You can have multiple signal listeners for any signal.

I have attached a simple sample process that demonstrates both inline and boundary catch events responding to the same throw event.

Hope this helps,

Greg
