> Priority: Minor
> Fix For: 0.8
>
>
> Creating an invoker class by implementing the Invoker interface requires you
> to implement the invoke, parentEvents, and cancel methods. The invoke method
> is expected to perform the invoker's task and the user must trigger a special
> done event within it to signify the invoker is complete. The cancel method is
> expected to be called from the outside to cancel the invoke process,
> especially if the invoke process were being handled in a separate thread and
> the thread has become a zombie. It would be called if an event were triggered
> while the state engine was within the state containing the invoke, since that
> event would be expected to interrupt the invoke. The issue, however, is that
> the cancel method is called even if the triggered event is the special done
> event signifying the end of the invoke, causing the cancel method to always
> be called regardless of whether the invoke was indeed a zombie or not.
> The system should work so that the special done event triggered while in an
> invoke should not cause the cancel method on the invoker class to be called.
> An investigation should take place to determine if this should apply to any
> event triggered by the invoker itself (though I am not sure how you are able
> to make that determination if the invoker spawns off separate threads that
> could trigger the events) should cause the cancel method to be called.
