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.

possible?
