With the following renderer code I could get rid of the warning
(I guess it's not ok to use {data.label} in the renderer),
but unfortunately the "tl2" scrolling problem is still there -
MyRenderer.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml";
verticalScrollPolicy="off" horizontalScrollPolicy="off"
width="100%" height="100%">
<mx:Script>
<![CDATA[
override public function set data(value:Object):void {
super.data = value;
var str:String = String(value.label);
myLabel.text = str;
myLabel.setStyle('color', findColor(str));
}
public static function findColor(str:String):uint {
return (str.indexOf('♥') != -1 ||
str.indexOf('♦') != -1) ? 0xFF0000 : 0x000000;
}
]]>
</mx:Script>
<mx:Label id="myLabel" truncateToFit="true" width="60"/>
