The PureMVC Framework Code at the Speed of Thought

Since the documentation states that the command registered last should be the one used, we propose a different implementation which in our Java port currently looks like this:

   public void registerCommand( String notificationName, Class commandClassRef )
   {
      if (null != this.commandMap.put( notificationName, commandClassRef )) return;
      this.view.registerObserver( notificationName, new Observer( new IFunction()
      {
         public void onNotification( INotification notification )
         {
            executeCommand( notification );
         }
      }, this ) );
   }


We replace the command if one was registered before, but do not add another observer. Okay with you?
