有关list效果的难题，应该是超难的问题吧
下面代码中有两个LIST，一个BUTTON。点击BUTTON时为数据源啬增加一项，两个LIST里的内容也都增加一项。当第一次点击时是正常的两个LIST都能显示出效果。但当第二次点击时，两个LIST的效果都没了。
但是若将第二个LSIT删除，这时无论点击多少次，唯一的这个LSIT中始终能正常显示效果。

[解决办法]
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:DefaultListEffect color="0xccccff"
fadeOutDuration="2000"

<mx:DefaultListEffect color="0xccccff"
fadeOutDuration="2000"
id="glow1"/>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"

private var dp:ArrayCollection=new ArrayCollection([{name: "John Smith", position: "developer"}, {name: "Ellen Smith", position: "manager"}, {name: "James Smith", position: "accountant"}, {name: "Jane Smith", position: "designer"}]);
private function addItem():void
{
dp.addItem({name: "Jim Smith", position: "Janitor"});
}
]]>
</mx:Script>
<mx:List width="300"
itemsChangeEffect="{glow}"
dataProvider="{dp}"
editable="true"
labelField="name"/>
<mx:Button click="addItem()"
label="add item"/>
<mx:List width="300"
itemsChangeEffect="{glow1}"
dataProvider="{dp}"
editable="true"
labelField="name"/>
</mx:VBox>
</mx:Application>
这样就可以了.
DefaultListEffect 是不是不能同时作用俩个list.
但为什么第一次可以?(以后就显示不效果了)
