State machines and triggers within activities

[mbenson]

What is the correct way to call a trigger within a Do bahavior? When I attempt it, I get into an infinite recursive loop situation. This appears to occur because when the trigger is called, it first calls _do, which calls the trigger, which calls _do, which calls the trigger, etc... I'm new to BOUML, though I've used other modeling tools for many years. In my opinion, calling a trigger within a state activity is normally a bad idea to begin with. Normally, I would use a transition with a guard condition instead, but I'm having another problem regarding guard conditions (in another thread). Is there a correct way to call triggers from within state activities?

Hello,

I see first your other thread and answered to it.

No the correct way for the code produced by the state machine generator is not to call a trigger in a do behavior, the trigger must be applied on the state machine (not a sub state) at the toplevel

Please refer to my other answer for more details

Yes, the questions were related. Thanks. That answers both.
