Thanks for replying.
Lets talk about MVC. there are two different implementation of
MVC. One is Event driven, Which means call The Model(Service) in
Action. In JAVA Framework, JSF is the one. Another is Action driven.
Which means dispatch and Central listen. like Struts in Java.
I think my solution just call the Service in Every Flex Action.
not Dispatch to a Central controller.
The benefit is The logic is much more clear. and It is much more
easier to maintain, Because You always know which service is
used in the Exactly Flex Action(event).
compare the Cairngorm workflow:
View-->Action-->dipatch event--> frontcontroller-->command--
>delegate--->sevice Locator-->Modellocate--->View.
To:
View-->Action-->Service Facade-->Delegate-->Service locator-->Model
locator-->View
I relly think my way is much more easier and clearer.
Cheers
Mike
