Thanks for your help, Javi.I'll try the
doubleTrigger thing later. I'd like to seek your advice about other two
problems: 1.can action be nested in another action for convenience? 2.When
two events are simultaneously triggered, by a request message and a response
message respectivel, two transitions may be aroused for the involved entry
state( only one transition has a target state and the other has only actions but
no state transition), I wonder is it allowed.
Any advices will be
appreciated!
