感谢您的help.Now我赶上一个错误，而draging的itemRenderer（我的Flex SDK是4.5.1）。
我的清单itemRenderer：

thanks for your help.Now I catch an error while draging the itemRenderer(my flex sdk is 4.5.1). My list itemRenderer:

<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
            xmlns:s="library://ns.adobe.com/flex/spark"

            width="100%" height="100%">
    <fx:Script>
    <![CDATA[
        import mx.events.CloseEvent;


        override public function set data(value:Object ) : void{
            super.data = value;
        }

        protected function closeHandler(event:CloseEvent):void
        {
            //ToDo
        }

    ]]>
</fx:Script>
    <s:TitleWindow x="0" y="0" title="{data.label}"
               width="100%" height="100%" creationPolicy="all"
               skinClass="skin.titleWindowSkin" 
               close="closeHandler(event)">
    <s:Label text="{data.value}"/>

    <s:TextInput x="123" y="58" text="@{data.value}" 
                 focusIn="parentDocument.owner.dragEnabled=false" 
                 focusOut="parentDocument.owner.dragEnabled=true"/>

</s:TitleWindow>
</s:ItemRenderer>

虽然draging，捕获错误等：
