Hi
 
yes you are right , and i shorten the calls for simplicity. the question is how the the userVO object is shared among all those
View--Helper--Control--Delegate
 
i understand that the helper pass it on but where is it best to define it , on the helper ? or the view ??
 
 
thanks

disclaimer: i'm new to actionscript and caingorm so i could be mistaken.

From what I understand, you should not be accessing any services from the viewhelper.
Broadcast a FrontController.SAVE_USER event with the UserVO as data inside the
viewhelper instead. this should invoke the SaveUserCommand which calls your
AccountDelegate's saveUser method which calls the service's saveUser.
