endEntry ... like in QHsmTestSM>>dispatch: of course !
I have read your code for FSM because I will need it to implement a
communication protocol. Sorry, I forgot.

You're a master.

Thanks

Have you tried #endEntry instead of #flush?

In the middle of the Morphic event loop, just after responding to events,
and
before doing other step methods and displaying the world.

Look for implementors of #addDeferredUIMessage:, look at the one in
WorldState, look for senders of #deferredUIMessages, and you'll see
WorldState>>runStepMethodsIn: which empties the queue.

And it's called from doOneCycleNowFor: which is  the body of the main
Morphic
event loop.
