我在Flex（Flash Builder 4）中有这个奇怪的问题，在HorizontalList它崩溃时，只要我滚动到快速，任何人有一个想法？ 这里是我的自定义项目渲染器HorizontalList崩溃滚动“太快”时
package

import flash.events.MouseEvent;

private var track:Object = null;

private var lbl:Label = new Label();
[Embed(source="gfx/noArt.png")]
[Bindable]
private var noArt:Class;
override public function set data(value:Object):void
{
trace(value);

try{
addChild(img);
addChild(lbl);
horizontalScrollPolicy = ScrollPolicy.OFF;
verticalScrollPolicy = ScrollPolicy.OFF;
setStyle("verticalAlign", "top");
setStyle("horizontalAlign","left");
track = value;
trace("Art: " + value.Art);
if(value.Art == "" || value.Art =="-")
img.source = noArt; else
img.source = value.Art; // << when I remove this part it works fine
trace("GAY");
img.height = 60;
img.scaleContent = true;
img.autoLoad = true;
lbl.text = value.c3;
lbl.width = 67;
lbl.height = 20;
trace("WAY");
img.useHandCursor = true;
img.buttonMode = true;
lbl.useHandCursor = true;
lbl.buttonMode = true;
trace("NAY");
img.addEventListener(MouseEvent.CLICK,arClick);
lbl.addEventListener(MouseEvent.CLICK,arClick);
}catch(E:Error)
{
}
}
private function arClick(event:MouseEvent):void
{
FlexGlobals.topLevelApplication.albumSearch("/album " + track.c3);
}
}
}
