StateMachineBuilder#onExit() method is returning 'to' state as null.

StateMachineBuilder#onExit() method is returning 'to' state as null.

Hi,

Unfortunately, current behavior is bydesign. The truth is the logic added on state exit should not care about the 'to' state, and also the state enter case should not care about the 'from' state. If you really need to know the 'to' state, you need to move your logic onto the transition which will pass both 'from' and 'to' state.

Thanks for the quick response! By transition you mean 'event' right? If that's the case, I'm good as I've already made this change as backup plan.

You can add your code in method "transitFrom[A]To[B]On[event]When[condition]" it will be called as its described.
But if you don't care about the condition and event, then you can add your code in method "transitFrom[A]To[B]" which means when state transition from 'A' to 'B' no matter what event caused and at what condition, this method will be invoked.
