Add a graphicsLayers

[ShaunWeston]

This is probably a simple answer, but for some reason I just can't get a graphics layer to add when I click on a map. THe alert "map clicked" does come up, but the point graphic layer is not added to the map?

   private var myGraphicsLayer:GraphicsLayer = new GraphicsLayer();
   
   private var configFeatureLayers:Array;
   
   //this function called when the widget's configuration is loaded
   private function basewidget_widgetConfigLoadedHandler(event:Event):void
   {
    if (map.loaded)
    {
     Alert.show("map loaded");
     loadHandler(null);
    }
    else
    {      
     map.addEventListener(MapEvent.LOAD, loadHandler);
    } 
    function loadHandler(event:MapEvent):void
    {
     map.removeEventListener(MapEvent.LOAD, loadHandler);
     map.addEventListener(MapMouseEvent.MAP_CLICK, clickHandler);
    }
    function clickHandler(event:MapMouseEvent):void 
    {
     showPopup(event.mapPoint);
    }
    
    function showPopup(mapPoint:MapPoint):void
    { 
     Alert.show("map clicked"); 
     myGraphicsLayer.clear();
     var graphic:Graphic = new Graphic(mapPoint, clickPtSym);
     myGraphicsLayer.add(graphic);

Oh yeah thanks,

I managed to fix it and get it working, I'm not sure exactly what the problem was.
