> The mouseDown handler of the flashx.textLayout.container.ContainerController may cause a null object reference error
> (here the code with original comments)
> {code}
> 		public function mouseDownHandler(event:MouseEvent):void
> 		{
> 			if (interactionManager && !event.isDefaultPrevented())
> 			{
> 				interactionManager.mouseDownHandler(event);
> 				// grab the focus - alternative is to listen to keyevents on the Application
> 				// is this necessary?
> 				if (interactionManager.hasSelection()) 
> 					setFocus();
> 			}
> 		}
> {code}
> The error occurs in the line interactionManager.hasSelection() because interactionManager.mouseDownHandler(event) may cause the textFlow to become null and therefore the interactionManager can be null in that line.
