intermediate-event throw/catch-mechanism

[cavdar]

Hi,
I am trying to understand the intermediate-event throw/catch-mechanism. Belov is my process definition. Why the task "UserTask #2" is never reached?
Thanks for any help.

Hi Cavdar,

I do not see your process definition. The best way to communicate an issue (or to learn something in Activiti) is jUnit test (from my point of view).
https://forums.activiti.org/content/sticky-how-write-unit-test

jUnit tests more related to your topic:
org.activiti.engine.test.bpmn.event.timer.IntermediateTimerEventTest

in activiti6 source.

[cavdar]

sorry. process definition is attached now.

[cavdar]

Problem solved:
the process throwing the event must not be the same as the one catching it.

Cavdar, show us how did you solve the problem.

I splittet my UserTasks in two process definitions. See attached files.
