    reload a method during a variable change

      I want to run a method when a variable changes.. Some sort of listener on the variable.. Something like that.. Is it possible? Any ideas?

          One way to do this is to use a setter function. to the outside, it looks just like a variable, but is really a function in which you can do whatever you want. It has a special format:

          [Bindable]private var _sMyString:String;

          public function set myString(sValue:String):void {
          _sMyString = sValue; //normal variable stuff
          //now do whatever special processing you need to do.

          Use this property like this
          myString = "someValue";

          this.myString = "someValue";

          myClass.myString = "someValue";

          You can also look into changeWatcher()
