CompositeEventActivity<TInstance> and GraphStateMachineVisitor<TInstance>

[AlexanderRadko]

GraphStateMachineVisitor has code that is impossible to execute.

inside method Visit(Activity activity, Action next)
system is trying to cast activity to CompositeEventActivity:
compositeActivity = activity as CompositeEventActivity;

but in case of registering composite event system creates FactoryActivity with CompositeEventActivity so cast is impossible and method GraphStateMachineVisitor.InspectCompositeEventActivity never executes
