Hi, I'm having a trouble with a state machine particular case (using Qt 5.3). My state machine has two parallel macro-states. One is meant to model the GUI evolution, the other one is meant to model the controller evolution. Since in both states there's a complex structure, for practicability, I use a local transition to reach some important states from any other states. I've provided a simplified schematic at http://gdurl.com/l9km. As you see for both Controller and GUI sub-states, the first state is reachable from any other state. Using this state machine structure, whenever a local transition triggers, it will cause an exit() from the Parallel-container state, "resetting" the other independent parallel state. For instance, with reference to the proposed example, suppose to be in Controller's Second state and in the GUI Third state. If the GUI local transaction is triggered (to reach its First state), even for the Controller parallel state that happens, since the Parallel-Container for some reason exits and re-enters in itself (which should not happen since the local transactions doesn't start from it). In order to make the thing working anyway, I've made a "wrapper" state for each parallel state (i.e. GUI-wrapper and Controller-wrapper), which intercepts the "exit", without involving the other parallel states into a reset a caused by a global Parallel-container exiting and re-entering. I think that this is an issue worthy of discussion.
Hope that helps, and thanks in advance for any clearance. Alessandro.
