Manually restarted a task and when process completed does not return to parent p

Edit the sub-process and add a terminate event to the end node. Then go back to the monitor view and start the end event again. This should return back up to the parent process.

Ok. Let me see if I understand this.

Monitoring/editing an in-flight process, adding a terminate node for a process that has been restarted will allow it continue back to the parent calling process. I'm slightly confused. Doesn't terminate event kill (end) the entire process including the parent chains? Unless my understanding is wrong, why the different treatment of terminate event?

The termintae event will only end the current process and any child sub-processes that have been started synchronously. It will not have any affect on the parent process that started it.
I think you can also cancel the previous instance of the node (that I assume error'd) before restarting it, this should also allow the chain to return back to the parent.

This error i have encountered before and for this you have to kill previous instances of the node. This is just a checkbox you have to select in Others tab.

Hi brian,
Above two points are the valid and possible solutions to the issue encountered for you.
When a node crashed in a sub-process, which does not have a terminate event, even after fixing the issue and the flow reached end event the instance will still be active as the node which got crashed will be with the status "Unattended".
And so this leads to the main process to wait infinite time for the sub-process to get terminated.

With any of the above implementations, it gets resolved. But the solution - checking the property “Delete previously completed/cancelled instances” in “Other” tab - is most suitable when you implement a flow that includes more than one node to undergo a loop (not MNI).
So, please try placing a terminate event in the process model that you have configured in the sub-process mode and publish it so that you can avoid these kind of crashes in future.
