Question

Maybe it is a bad habit which I still have since Flash Professional, but I’m trying to add a simple Sprite or/and Bitmap I just created to an empty Application and it’s not happening.

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" 
               minWidth="955" minHeight="600" 
               creationComplete="application1_creationCompleteHandler(event)">

    <fx:Script>
        <![CDATA[
            import mx.core.FlexGlobals;
            import mx.core.UIComponent;
            import mx.events.FlexEvent; 


            protected function application1_creationCompleteHandler( event : FlexEvent ) : void
            {
                var s:Sprite = new Sprite();
                s.graphics.beginFill( 0xFF0000, 0.5 );
                s.graphics.drawRect( 0, 0, 100, 100 );
                s.graphics.endFill();

                this.addChild( s );
            }

        ]]>
    </fx:Script>
</s:Application>

Could someone tell me what I am doing wrong and help me correct it?

Try putting your sprite in UIComponent or SpriteVisualElement.
This works for me:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
               creationComplete="test()">

    <fx:Script>
        <![CDATA[
            import spark.core.SpriteVisualElement;

            private function test():void
            {
                var sprCont:SpriteVisualElement = new SpriteVisualElement();
                sprCont.horizontalCenter = 0;
                sprCont.verticalCenter = 0;

                var spr:Sprite = new Sprite();
                spr.graphics.beginFill(0xFF0000);
                spr.graphics.drawCircle(0,0, 100);
                spr.graphics.endFill();

                sprCont.addChild(spr);
                addElement(sprCont);
            }
        ]]>
    </fx:Script>
</s:Application>

For some reasons the ‘s:Application’ tags are not shown, but they are there.
