Question

I want to use vkontakte’s new wrapper feature, that enhances your application abilities by running under SWF wrapper.

This is a sample application that uses this mechanism. It uses pure action script to display it’s contents rather than an mx:Application.

Using the wrapper on my mx:Application failed due to the following error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
 at mx.managers::FocusManager/activate()[C:\autobuild\galaga\frameworks\projects\framework\src\mx\managers\FocusManager.as:702]

So I figure I could create a wrapper to the wrapper that can launch my application and came up with this (DummyApp is the application I want to lunch):

package 
{
 import Components.SidePanel;

 import flash.display.Sprite;
 import flash.events.Event;

   public class AppWrapper extends Sprite 
   {    
     public function AppWrapper() {
      this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
     }

     public function onAddedToStage(e: Event): void {
      var mainApp:DummyApp = new DummyApp();

      this.removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage); 
     }
   }
}

Unfortunately – it also failed, and the question remains, how to start Application from a simple AS file?

Answer 1

Vkontakte’s wrapper is now supporting Flex, which makes this question obsolete.
