Thanks Maceij,
That is very helpful! But you lost me a bit with: "...only one task and interrupting
signal boundary event attached to the sub process."
I created an embedded sub-process. In that sub-process is a start event, a diverge (AND)
Gateway, splitting to the separate Human Tasks (HT) for each team, a converge (AND)
Gateway, and a stop event. (This sub-process seemed logical, because I have several
(currently only 2) teams making the same evaluation. I expect to add more teams
eventually, but not soon.)
I noticed that the embedded sub-process Component has an Exception Handlers property, and
so I tried to mimic "BPMN2-ErrorBoundaryEventInterrupting.bpm2" from the
examples.
From here I got stuck. I couldn't get it to work at all, until I
copied the Event naming exactly. Then I tracked some of the hard coded aspects down to
the "org.jbpm.bpmn2.xml.ProcessHandler" class. It looks like my event types
(and handling code) are limited/fixed. I suppose I can handle this as an Error, although
it's really not.
From your reply, I think you are suggesting that I separately wrap
HT-2 and HT-3 (from my example) in embedded sub-processes to make them "boundary
aware." If that's correct, and I'm probably misunderstanding you, how would
I make a "Yes" from HT-2 cause HT-3 to end (complete/cancel)?
I don't want to loose site of my goal, which is to have a "Yes" answer from
one of the teams cause the other pending HT(s) to end immediately and the process to move
on.
If I am on the right track with the sub-process I described, how should I raise the
exception? It looks like I would have to use separate XOR Gateways to separate Error
Events after each HT, and use separate Exception Handlers on the sub-process boundary,
separate signal events, etc. Is that correct, or is there a cleaner, single handler,
approach? Also, since one of the HTs did complete, how do I ensure that it's Result
Mapping variables also propagate for down-process tasks to use?
Thanks again.
