Asynchronous Tasks Continuation

I've a very simple requirement that it seems almost textbook case, but I can't seem to find it in the examples that I've found over Google or using the search function of the forums (perhaps I'm using the wrong term? "asynchronous")Basically, I've a process that requires an execution of a remote ser

Figured it out. The only way this seems to work for me is if I use a ServiceTask (with the Asynchronous flag set) with a sequenceFlow to a MessageStartEvent (with the message configured on the Process). I tried a whole slew of others (including having an EventSubProcess and a SubProcess with various start events) and this is the only combination that seems to work. Not sure if it's the right one, though.

The way this is typically handled is either
- use a combination of a service task that sends out a message and a receive task afterwards. The message coming back will have to use the executionId to correlate
- use a custom ActivityBehaviour (NOT JavaDelegate) that does the sending + waiting for the message in one step (similar to previous, but visually in one step)

could you perhaps give an example of implementing the above.

Thanks.
