[flexcoders] Databinding to xml attributes as3/flex

[hoseyhosey]

I am writing a component that needs to change its view based on an
xml's changing attributes
[Bindable]
var xx:XML=
<a>
  <b id="1" show="true">
</a>
public function wee(){
  trace("hi")
}
myWatcher=ChangeWatcher.watch(this.xx, ["a","b","@show"],wee);
 
I know that the flex components can update their "view" when an xml
changes, but I dont seem to be able to make it work.
 
Any Ideas?
Thanks
Hosey
