It sounds so simple but has me stumped at the moment. I'm sure there must be a simple solution but for the life of me I can't figure it out... E.g. say I have a property testProp which is maintained by my class and must not be publicly set-able from outside. I do however want outside users to be able to bind to testProp so that they receive notifications when it changes. An example of a read-only bindable property would be ArrayCollection.length. You can bind to this but cannot change it. How do I do the same thing with testProp? I tried... protected var _testVar:uint = 10; [Bindable] public function get testVar():uint { return _testVar + 1; } protected function set testVar(value:uint):void { _testVar = value; } ...hoping to hide the setter from the outside world but outside users CAN still change testProp with myClassInstance.testProp=10!! Thanks for your help, Nick.
