TerminateEndEvent terminates the whole process tree (since 5.18/5.17)

benpr — Thu, 08 Oct 2015 17:59:41 GMT

Hello,with the activiti engine 5.16.1 the terminateEndEvent terminates only the current process. Since 5.18 (or 5.17) this event terminates all processes in the whole tree.Exists a new (or other) endEvent to normally end only the current process?The normal endEvent doesn't work in my use case becaus

Hi Ben,

In the case when you cancel process instance A (parent for the process instance B) what should happen with the process instance B?

Manually Cancel: The parent process waits for the other childs.
Or do you mean cancelation with the cancelEndEvent?

Hi Martin,

in my case I don't won't to end other subprocesses. I just need to normally end a child process.
My Child process arrives the endEvent but it doesn't end/stop. There's another path with a signalCatchEvent.

In 5.16 I've used the terminateEndEvent. The process arrives the terminateEndEevent and cancel it's own signalCatchEvent and the process is stopped. Now in 5.18 the terminateEndEvent not only stopps the current child process but also the whole tree with the parent and all other childs.

I need a way to normally stop one process with all it's own paths without waiting for SignalCatchEvents.

Sample:
<code>
Process –> parallelGateway –> SignalCatchEvent –> …
|——-> Usertask… –> EndEvent (or in 5.16 TerminateEndEvent)
</code>
When the process arrives the EndEvent it should stop and don't wait for the SignalCatchEvent.
See the TestEndEvents.bpmn.txt.

regards,

Ben

See my sample process from the other post.
I deploy this in the activiti explorer with the demo project. The timer should pause the process one minute. After this the endEvent arrives.
But the process is still running after 2 minutes and so on.

Can you give me a sample how to redesign this process to end/stop this process after arriving the endEvent?

Hi Ben,

I do not have a working sample, I have a suggestion.
Instead of end event use throw (e.g. message, signal) an event. Catch this event in the parent process call activity boundary event and terminate the step.

Martin

Hi Martin,

thanks for your reply.

> Catch this event in the parent process call activity boundary event and terminate the step.
Can I use this in a multi instance call activity?
In my test the child processes can successful finished with "runtimeService.deleteProcessInstance" called from the "call activity boundary event". But the "call activity" doesn't see that the child is finished. So it waits for the child's and the parent process hangs.
See sample in attachment.

What is the best practice or normal way to end a _single_ process (no parent) with waiting catch events?

Is it planned to re enable the old terminate end event functionality (terminate only the current process) as option in an end event?

Theres another problem:
Since 5.17/5.18 "call activity" don't see the end state then the child process is deleted programmatically. It waits for the child although the child is finished.

Regards, Ben

Try.

Since 5.17/5.18 "call activity" don't see the end state then the child process is deleted programmatically. It waits for the child although the child is finished.

Because you have deleted child process you have to take care of the parent execution. (e.g. you can signal execution to continue….)

In 5.16 it worked. How can I manual signal the multi instance "call activity" element that one instance has finished?

"Is it planned to re enable the old terminate end event functionality (terminate only the current process) as option in an end event?"

We're looking into it. There are a few users noticing the very same problem.
Thanks for the bpmn processes, that helps.

Do you have a Jira Ticket for me, to stay up to date?
Exists a release plan and/or a release date for the next version?

Just created this one : https://activiti.atlassian.net/browse/ACT-4080

No release date yet, but we're thinking about a 5.18.1 release, which would contain bug fixes. That probably is 2-3 weeks away.
