Hi again
Let me explain it better. There are two options:
1. The manager class (ManagerFSM) exposes a method. Within the method, we
call context.actorOf(....). But such method is part of the actor and NOT
ActorRef. I do not know how to access such method from a client code.
Perhaps, I misunderstand something here?
2. The second alternative is based on passing a Message to ManagerFSM.
Here, I struggle with FSM state handling mechanism. I cannot see an option
that sound "when(_){context.actorOf{...}".
Perhaps, I misunderstand something here?
In advance thank you very much.
Best regards
Nader
