The approach I have used in this case is the ChangeWatcher class (mx.binding.utils)
-------------------------------------------------------------------------------------------------------
// set up the watcher when the app loads
private function doInit():void
{
ChangeWatcher.watch(changeText,"text",updateResultsPopup);
}
// call this function anytime 'changeText' component is changed
via the model
private function updateResultsPopup(event:FlexEvent):void
{
//do something
}
<!-- this component lurks at the bottom of the template, listening for
change -->
<mx:Text id="changeText" text="{modelLocatorAdmin.updateResults}"
height="0" width="0" visible="false"/>
-------------------------------------------------------------------------------------------------------
there is probably a better way of achieving the same result, but this works

a property to a function

Please respond to flexcoders
Is it possible to bind a property to a function... A bit like the MVC-pattern…
When a property changes, a function should be triggered…
BindingUtils can’t seem to do this.
Thx, Lieven Cardoen
