[FEATURE] Provide state information to unexpected event handler #144

Closed erikzenker closed 3 years ago

erikzenker commented 3 years ago

Problem

The unexpected event handler does currently only get the event as an parameter, but the current state is unknown to the handler. Thats makes it harder to debug in which state the unexpected event was triggered.

Proposed Solution

Provide the current state and parent state to the event handler (at least a string representation of it)

erikzenker commented 3 years ago

Could be implemented by providing something similar to the dispatch table e.g.: unexpectedEventHandlerTable, that contains for every event an array that points for every state id to the unexpectedEventHandler with a call operator.

Fixed with #157
