i learned the help. but still confused!
what's difference of enterState ,exitState and
i know the currentStateChange and currentStateChanging , when
i set currentState="", i can catch the event of currentStateChange
but how and when i could catch the event of enterState and
in a test, i catch the exitState only once.
in that test i wrote the exitState and enterState event in
Application. published, i found that i only catch once of the
exitState event when i change the Application's currentState, and
only once, after that,whatever i change the currentState, i can not
catch exitState event again, and i did NOT catch enterState once
all the time.
so why? where should i use enterState and exitState?
