Yes, there is no more ActionHandler, and we still could make process run successfully.
If you want to do something when one transtion be taken. You could use event-listener.
If you have a state activity with three transition. There will be some possibilities.
First, you want to let someone invoke ExecutionService.signalExecutionById(id, signalName); to let the process continue to run, at this possibility we needn't use condition in transition.
Second, you want to use process variable to decide which transition should be take. So you could add a DecisionActivity after the state, you could add condition attribute in the DecisionActivity's outgoing transitions.
Third, you want to waiting for a while, and let one of transition be taken automaticly, Then you could use timer to do this.
Thank You Very much for your reply and for yoour time.
