Papervision and event dispatcher

Hello,

I’m a Papervision newbie and I’m a bit stuck here.
I created a class that extends the displayObject3d and
added an Event dispatcher like bellow:


package {     
import flash.display.Sprite;     
import flash.display.Stage;     
import flash.events.Event;     
import org.papervision3d.objects.DisplayObject3D;         
  
public class dummyO extends displayObject3D{ 

public function dummyO(){ 

dispatchEvent(new Event("START_OF_DUMMYO")); 
init(); 
} 

private function init():void{ 
//start doing stuff 

}}} 

but unfortunately the event never dispatches.
Any idea why this is happening and what can I do to fix this?

thanks a lot!
