In addition to what Matt has said: it depends on when you're firing your validator.
in MXML do validation on user event: <mx:CheckBox click="myValidation()" .../> -or- <mx:CheckBox buttonDown="myValidation()" .../> If you're doing it programmatically in AS, you can add an event listener for mouse events for this target. myCheckBox.addEventListener(MouseEvent:MOUSE_UP,myValidation); Either way should give you real-time error checking.
