I believe you can only bind vars and setters. By binding a function i
think it will only execute the function once. An easy workaround is to
have a var containg the result of the toString function and bind the
property to that var. Something like:
[Bindable] public var stringValue:String = "";
public function toString():String {
stringValue= this.toString();
return stringValue;
}
<mx:Label id="lbl" text="{data.nameID.stringValue}"/>
