Active events on completed tasks

[leonhardtdavid]

Hi!!

I'm new in Activiti, but I'm having a problem on a single task in my process.

I can't finish a process instance because I have active events belonging to finished execution.
I'm using activiti 5.11 and the activiti designer.


Thank you very much,
David.

'active events' … i have no clue what you mean with that.
Could you describe your problem a bit better?

[leonhardtdavid]

Sorry.

I have two rows in ACT_RU_EVENT_SUBSCR with an execution id and that id is not in ACT_RU_EXECUTION or ACT_RU_TASK.

Thanks.

What's the error stack trace?

This is the link to the error stack trace:

Really strange issue … can't directly see how it could be caused.
Is there any way you can create a reproducable unit test?

[leonhardtdavid]

It is quite difficult to do, since I've seen happening in a particular task and not always.

[jbarrez]

well, can't you use that particular task in a unit test 😉

Otherwise it's pretty hard to validate for us.

Hello again,.

I understood when I have the problem, so there is de unit test (I used a boundary event signal, is the same for a timer):

I use this template: https://github.com/Activiti/activiti-unit-test-template

Thank you.

Thanks, excellent unit test.

I tried your unit test (on 5.15-SNAPSHOT), however it only failes on

<code>
assertTrue(signals.size() == 0);
</code>

which is logical, since the signal is global and not process instance scoped (activiti:scope="processInstance").

So it seems your issue is fixed in a later version of Activiti.
