thanks for the hint to migrate to RC1:

Another hint for people migrating from M2 to RC1, you may have to change your flex code that handle the login result event.

I was using the following code

Code:
	// Handle successful login. 
		private function LoginResultEvent(event:ResultEvent, token:Object=null):void
		{
			
			switch (event.result)
			{
				case "success":
					Alert.show("Login OK: ");
					dispatcher.dispatchEvent(new LoginEvent(LoginEvent.LOGIN_SUCCESSFUL));
					break;
				default:
			}
		}
which does not work anymore in RC1 since user details are now returned by the server upon login
Extracted from reference documentation here is a code that works

Code:
var token:AsyncToken = myChannelSet.login("jeremy","atlanta");
token.addResponder(
	new AsyncResponder(
  		function(event:ResultEvent, token:Object = null):void {
  			if (event.result.authorities.indexOf("ROLE_ADMIN") >= 0) {
  				displayAdminPanel(event.result.name);
  			} else {
  				displayUserPanel(event.result.name);
  			}
  		},
  		function(event:FaultEvent, token:Object = null):void {
  			displayErrorMessage("Login Failed: "+event.fault.faultString);
  		}
  	)
);


BTW Thanks for the RC1, I can't wait testing the messaging feature!
