After a little more investigation, I made the myMethod look like this:
public function myMethod(arg:Number):void{
Alert.show("-" + this.getChildren().toString() + "-");
}
As it turns out, it's not finding anything in the headerRenderer (even
though I can see the ComboBox on the stage). Anyone know why it's
doing this?
