Scenario: User type login data, proxy invoke loginMethod on server which after succesfull login return collection of user data (id, username, password, fname, lname, address, email etc.), now...
After succesfull login loginControll is removed and application is in new state, here I wan't to display userDetails but I don't know how :(. After login where should I store returned users data so that I can use them later, and how to retrive them when I need them?

In a Proxy.

To retrieve from a Command, Mediator or another Proxy: facade.retrieveProxy(proxyName)

-=Cliff>

loginUserData is always null when I try to call it from mediator :(

LoginCommand
public class LoginCommand extends SimpleCommand implements ICommand
{
override public function execute(notification:INotification):void
{
var myUser:User = notification.getBody() as User;
var loginProxy:LoginProxy;
loginProxy = facade.retrieveProxy(LoginProxy.NAME) as LoginProxy;
loginProxy.tryLogin(myUser.username, myUser.password);
}

}
LoginProxy
public class LoginProxy extends Proxy implements IProxy
{
public static const NAME:String = "loginProxy";


private var loginRemoteService:RemoteObject;

public function LoginProxy()
{
super(NAME, new User());


}

override public function onRegister():void
{
loginRemoteService = new RemoteObject("fluorine");
loginRemoteService.source = "BL.Sample";
loginRemoteService.LoginUserByEnteredData.addEventListener(ResultEvent.RESULT, onResult);
loginRemoteService.addEventListener(FaultEvent.FAULT, onFault);
}

private function onResult(evt:ResultEvent):void
{
data = evt.result as User;
sendNotification(ApplicationFacade.LOGIN_SUCCESFUL, loginUserData);
}

private function onFault(evt:FaultEvent):void
{
sendNotification(ApplicationFacade.LOGIN_FAILED);
}

public function get loginUserData():User
{
return data as User;
}

public function tryLogin(p1:String, p2:String):void
{
loginRemoteService.LoginUserByEnteredData(p1, p2);
}
}
Mediator
override public function handleNotification(notification:INotification):void
{
switch (notification.getName())
{
case ApplicationFacade.LOGIN_SUCCESFUL:
var uProxy:LoginProxy;
uProxy = facade.retrieveProxy(LoginProxy.NAME) as LoginProxy;
var u:User = notification.getBody() as User;
Alert.show("welcome: " + u.realName+ ", " + u.City);
break;
case ApplicationFacade.LOGIN_FAILED:
Alert.show("sorry pal, wrong password");
break;
}
}


Ok, problem solved, my friend with more experience help :)

I made stupid mistake, I have wrong mapped User VO, instead this:
[RemoteClass(alias="BL.User")]
Now I have this:
[RemoteClass(alias="DemoFluorine.BL.User")]

Thats why service returned me ObjectProxy
