List Component not working

programming flash
1

Hi Having a problem getting a list component to display. Wondering can you edit the below to show me how to get it to work


package 
{
	import flash.display.MovieClip;
		import fl.controls.List;
		import fl.events.ListEvent;
	
	/**
	 * ...
	 * @author S
	 */
	public class testScript extends MovieClip
	{
		var bordorList:List = new List();
				
				public function testScript()
				{
			bordorList.addItem( { label :  "Closed" } );
			bordorList.addItem( { label :  "Open" } );
			bordorList.addItem( { label :  "Circular" } );
			bordorList.setSize(40, 100);
			bordorList.move(602, 440);
			this.addChild(bordorList);
					
					
				}
				
				
	}
	
}

Error is :

TypeError: Error #1009: Cannot access a property or method of a null object reference.
