I want to draw sprite on Graphics layer like this:

            var sp:SpriteVisualElement = new SpriteVisualElement();
            sp.graphics.beginFill(0x00ff00,1);
            sp.graphics.drawRoundRect(10,10,100,100,150,150);
            sp.graphics.endFill();
            var myGraphicMarker:Graphic = new Graphic();
            myGraphicMarker.symbol.draw(sp,geom,null,map);
            graphicsLayer.add(myGraphicMarker);

It complaints at line myGraphicMarker.symbol.draw(sp,geom,null,map); about that TypeError: Error #1009: Cannot access a property or method of a null object reference. Can anyone please guide me what to pass instead of null to make this sprite drawn. Thanks

I'm assuming that Graphic is the esri graphic object and not the flash one. symbol is null in this case. therefore you cannot reference it. – CrazyEnigma Jan 31 '12 at 12:35

I extended the com.esri.ags.symbols.Symbol and then drawn on the sprite. – Omega Cancer Apr 26 '12 at 9:21
