To go back to your original example, it does seem a bit kludgy to me too. In this case I would use databinding like so:
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"; width="500" height="800"> <mx:Script> <![CDATA[ [Bindable] public var imageSource:String; ]]> </mx:Script> <mx:Panel x="100" y="100"> <mx:Image source="{imageSource}" x="10" y="10"/> </mx:Panel> </mx:Canvas> If I'm making MXML components I often do stuff like that and just use bindable public properties to pass through variables, which works well for these simple cases.
