Getting strange runtime error on very simple swf when I try to render.

Error#1009 null has no properties.

You are getting this error because you are referencing the application stage before it has been added to the host application's stage ( SWFRenderer ). Here is a Fix:

package 
{
   import flash.display.MovieClip;
   import flash.events.Event;
   import flash.utils.setTimeout;
   
   public dynamic class MainTimeline extends MovieClip
   {
      public function MainTimeline()
      {
         super();
	 addEventListener(Event.ADDED_TO_STAGE , addedToStage ) ;
      }
      public function addedToStage( e : Event ) : void
      {
	setTimeout( startApp , 1 );// Added a timeout to give loaderInfo time to initialize
      }
      private function startApp() : void
      {
	 trace( loaderInfo.width);  // FIX: best option to use if you can;
	 trace( stage.stageWidth ); // could throw an error as you are accessing the application domain
      }
   }
}
