Strange behaviour query/signal multi instance receive task

[aapthorp]

I have a process with a multi instance receive task i.e. one instance for the number of messages I expect to receive before the receive task completes.

When I query the receive task (as per the user guide but returning a list) I always get one extra execution returned. i.e. expect 2 get 3, etc. The returned ids always match what I find in the database (ACT_HI_ACTINST) except for the second one. I can never find this id.

The behaviour then gets stranger. If I signal the first execution I get an NPE error. However, signalling the second execution succeeds!

Has anyone else run into this issue or has no one else tried multi instance receive tasks?

I assume the reason for one extra task, is in effect a parent for each of the individual tasks, but then how is this stored in the database?

At what point does the individual multi task get marked as ended? When each one is signalled?

Joram,

Great, that was quick - thanks.

Your test case imports all kind of funny stuff (eg com.procurics.rnd.model.*).
I cant run the test this way without the dependent code.

Getting the same error on line 104 in 5.13.1.  The error occurs while attempting to complete the last task of a process instance (using the REST API to complete).  The process definition has a multi-instance subprocess, but the last task is not within this subprocess.  Will post a solution if I find one.

Fixed.  The Eclipse designer did not show it, but the human task had 2 flows coming out of it, one of which went to an end activity, and one of which went to a service activity.  Removing the second flow solved the problem
