Grid + CellRenderer + getCellIndex

[silentx]

Weiss jemand warum dies in FlashDevelop nicht funktioniert, aber in
Flash schon? (getCellIndex immer undefined)

class grdMouseOver extends mx.core.UIComponent
{
	private var img:MovieClip;
	private static var PREFERRED_HEIGHT = 2;
	private static var PREFERRED_WIDTH = 2;
	private var getCellIndex:Function;
		
	public function grdMouseOver()
	{ }

	public function createChildren(Void):Void
	{
		
	}

	public function getPrefferedHeight(Void):Number
	{
		return PREFERRED_HEIGHT;
	}

	public function getPreferredWidth(Void):Number
	{
		return PREFERRED_WIDTH;
	}

	public function setValue(str:String, item:Object, sel:Boolean)
	{
		img = this.createEmptyMovieClip("img", this.getNextHighestDepth())
		with (img)
		{
			beginFill(0xff0000, 50);
			moveTo(0, 0);
			lineTo(50, 0);
			lineTo(50, 50);
			lineTo(0, 50);
			lineTo(0, 0);
			endFill();
		}
		var idxObj:Object = getCellIndex();
		img.itemIndex = idxObj.itemIndex;
		img.columnIndex = idxObj.columnIndex;
		
		trace(idxObj.itemIndex)
	}

	public function size(Void):Void
	{
		// do Nothing here
	}
