Re: [flexcoders] beta 2: possible styleSheet bug with Text and TextArea component

[Muzak]

Tried it in a seperate mxml file.
As soon as the Text component is inside a repeater, it throws an error.
Works fine when Text comp is not inside a repeater.

TextArea component always throws an error, repeater or not.


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; xmlns="*">

 <mx:Script>
  <![CDATA[
   import flash.text.StyleSheet;
   import mx.events.FlexEvent;
   //
   private var _stylesheet:StyleSheet;
   [Bindable]
   private var rep_arr:Array = [{id:0},{id:1}];
   //
   private function repeaterEndHandler(evt:FlexEvent):void {
    this._stylesheet = new StyleSheet();
    this._stylesheet.setStyle("p", {fontFamily:"Verdana", fontSize:10, 
color:"#996600"});
    this._stylesheet.setStyle(".boldStyle", {fontWeight:"bold"});
    var len:uint = _txt.length;
    for(var i:uint=0; i<len; i++) {
     _txt[i].styleSheet = _stylesheet;
    }
   }
  ]]>
 </mx:Script>

 <mx:Canvas width="100%" height="100%">
  <mx:Panel width="200" height="300">
   <mx:Repeater dataProvider="{rep_arr}" repeatEnd="repeaterEndHandler(event);">
    <mx:Text id="_txt" width="100%" height="100"/>
   </mx:Repeater>
  </mx:Panel>
 </mx:Canvas>
</mx:Application>
