I made this changes e still doesn't work, some one had another advice? My test app:
<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:com="*" xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"> <mx:TextInput id="tiTitulo" width="200" maxChars="100" change="descCounter.countChars(tiTitulo.length)"/> <com:CharCounter id="descCounter" maxChars="{tiTitulo.maxChars}" /> </mx:Application> My component: <?xml version="1.0" encoding="utf-8"?> <mx:Label text="{String(_charNumber)}" xmlns:mx="http://www.adobe.com/2006/mxml"; initialize="init()" > <mx:Script> <![CDATA[ [Bindable] private var _charNumber:Number; [Bindable] private var _maxChars:Number; private function init():void{ _charNumber = _maxChars; } public function set maxChars(value:Number):void{ _maxChars = value; trace("MAXCHARS"+_maxChars); } public function get maxChars():Number{ return _maxChars; } public function countChars(value:Number):void{ var maxChars :Number = _maxChars; _charNumber = maxChars - value; } ]]> </mx:Script> </mx:Label> I receiving NaN instead of input maxchar value.
