Problems sending notification

[sinosoidal]

Hi,

I'm giving my first steps in PureMVC.

I'have already done a login system and now i want to use the framework to manage visual state as well.

For that i have tried to follow the slaker example.

The thing is that after the access is granted, in my access proxie I invoke an AccessGranted notification which will do the following

public class AccessGrantedCommand extends SimpleCommand {
      
      override public function execute (note:INotification) : void {
         mx.controls.Alert.show("im here1");
         
         var applicationMediator:ApplicationMediator;
         
         mx.controls.Alert.show("NOTIFICATION SEN1");
         
         applicationMediator = facade.retrieveMediator("ApplicationMediator") as ApplicationMediator;
         
         mx.controls.Alert.show("NOTIFICATION SEN2");
         
         applicationMediator.sendNotification(ApplicationFacade.MAINDISPLAY_MODE);
         
         mx.controls.Alert.show("NOTIFICATION SEN3");
      }
   }

But no notifitcation is being released. I have placed some alerts to see what is happening and the third alert is not called.

Can anybody help me here?

Thanks,

Nuno

You don't need to retrieve the ApplicationMediator to send a notification, in fact it won't work as you have it. It is the facade that sends notifications. The following will do:

:

public class AccessGrantedCommand extends SimpleCommand {
     
      override public function execute (note:INotification) : void {
         mx.controls.Alert.show("im here1");
         mx.controls.Alert.show("NOTIFICATION SEN1");
         
         facade.sendNotification(ApplicationFacade.MAINDISPLAY_MODE);
      }
   }
I'd also recommend putting your third alert in the listener for MAINDISPLAY_MODE to check if the note is being sent, rather than in the command. What you had only says the command completed, not that the notification sent.

Hi,

Thanks for the reply.

It is not working. Nothing happens.

I have an Alert in the ApplicationMediator handleNotification method and nothing happens there.

What can be wrong?

This is my ApplicationMediator:

:

public class ApplicationMediator extends Mediator
    {
        public static const NAME:String = 'ApplicationMediator';
       
        public function ApplicationMediator( viewComponent:Object )
        {
            super( NAME, viewComponent );   
        }
       
        override public function onRegister():void
        {
            facade.registerMediator(new MainDisplayMediator(app.mainDisplay));
        }
       
        override public function listNotificationInterests():Array
        {
            return [ApplicationFacade.LOGIN_MODE,
            ApplicationFacade.MAINDISPLAY_MODE]
        }
       
override public function handleNotification(note:INotification):void
{
mx.controls.Alert.show("im here2");

switch (note.getName())
{
case ApplicationFacade.LOGIN_MODE:
app.currentViewSelector = Main.LOGIN;
break;
case ApplicationFacade.MAINDISPLAY_MODE:
app.currentViewSelector = Main.MAINDISPLAY;
break;
           }
       }

        protected function get app():Main
        {
            return viewComponent as Main;
        }
Thanks,

Best regards,
