[Boost-users] [statechart] Unexpected events

I had assumed that if a state_machine definition did not mention any reaction for a particular event in a particular state, occurrence of that event in that state would be flagged as a runtime error. It appears that instead, the event is simply dropped. Can this behavior be changed? It would be tremendously helpful for debugging purposes. Adding an error state and a bunch of transitions into it seems like overkill, especially if the cross product between states and events is large but the "in- and out-degree" of states is small. -Dave
