[rules-users] FW: Nested flow terminating parent flow prematurely

Tue Jun 2 11:15:25 EDT 2009

Thanks to Travis Scheponik for trying to help me resolve this. However, neither he nor I could figure it out.
Babak solved it here at the boot camp - the subprocesses should have their end nodes with terminate set to TRUE not false, and the parent process should invoke the subprocess with WaitForCompletion set to true.

This was the one combination we had not tried, and it worked.
Thanks, Babak.

Subject: Nested flow terminating parent flow prematurely

Hi.
I'm struggling with a rule flow that contains another rule flow.
Rule flow 1 - first step is to invoke a sub-process, call it rule flow 2.
Rule flow 2 executes fine, with correct internal branching logic.
Rule flow 2 proceeds to an End object with terminates set to false.
After RF2 completes, I am expecting a return to the parent flow, RF1.
However, entire flow terminates and subsequent RF Groups and or RF's in parent flow are never activated.
Is this a bug or am I specifying something incorrectly?
Using Version 5.0.0.CR1

Code for the two flows is below (excuse the ugly ID's and names - these are generated from our rule repository software):
