Use Case
- create a process definition that manage more sub-processes's instances.
- after all sub-process are created wait until all sub-processes finish.

I implemented this use case using a Custom Fork that create the sub-process, but the problem with it is that the Join don't wait until all processes finish.
Could you give me an idea how to implement this?
Thanks
Next is my process definition and my action code.
