Changes

1. NewProcess = Define a new process [NewProcess].
2. if action must be executed only when process was suspended:
1. NewProcess.onSuspended overrides SaleProcess.onSuspended .
3. if action must be executed regardless of whether process was suspended or finished normally:
1. NewProcess.onFinished overrides SaleProcess.onFinished .

Constraints

• This hook works only with the Incorporate a new process hook.

Comments

• If you need to perform an action whenever the process was finished, but not when it was suspended, you can also override the getStopGate method. There you can define a sub-process that is guaranteed to be the last thing that is executed as part of the process. It must end at a null gate.

  If for some reason, you need to make sure, that the Gate/Transition mechanism has already stopped for the process, you must override onFinished and query isSuspended before performing some action. This might be the case if you want to send a notification if a process was finished.
