I'm a little bit lost in those replays :)
Next example will do next:
When array collecting which is data provider changes, selected index
will set to initial (for example second item - 1).
On page creationComplete, add event listener
<mx:... creationComplete="init()"...>
method implementation is following:
private function init():void
{
//Every time selectedProduct.typeNames changes method
WatcherListener will be called
ChangeWatcher.watch(this.selectedProduct, "typeNames",
WatcherListener);
}
public function WatcherListener(event:Event):void
{
productSubTypeCB.selectedIndex = 1;
}
