hi ralf :) how does the framework then detect changes to xml for databinding purposes? but thanks btw. i was trying to be lazy just adding a watcher in one place vs 20 odd places :(

Hi Johannes, i wouldn't expect this to work. This ChangeWatcher only fires, if you assign something to __dataCopy, eg. ---------------------------------------------- snip -------------------------------------------------- <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="vertical" creationComplete="onCreationComplete()"> <mx:Script> <![CDATA[ import mx.binding.utils.ChangeWatcher; [Bindable] public var __dataCopy : XML; private function onCreationComplete() : void { trace("ApplicationEntry::onCreationComplete " + url ); onCC(); } private function onCC():void { ChangeWatcher.watch(this, "__dataCopy", watcherListener); __dataCopy = new XML("<node1/>"); } private function watcherListener(evt:Event):void { trace("hhh:"); } ]]> </mx:Script> </mx:Application> ---------------------------------------------- snip -------------------------------------------------- This works fine. Since XML doesn't seem to have other bindable properties, any changes below __dataCopy can't be watched. Cheers, Ralf.
