下面的代码什么地方存在错误，期待高手解决
我现在有这么一段代码，就是弹出窗口，并加了特效的，效果能显示出来，但就是存在两个问题，第一：如果弹出窗口有ComboBox，并且这个ComboBox的数据是动态查询的，那么在ComboBox前面的Label将会错误，例如下面代码，“父节点”三个字会错位，第二：如果界面上又List控件，并且数据是动态的，那么List里面的数据显示不清，只显示数据的20%，不知道这样的问题如何解决，，希望大侠赐教：
 

XML code

    <mx:FormItem label="父节点：" required="true">    <mx:ComboBox id="parentNode" dataProvider="{departments}" labelFunction="disDepName" labelField="name" />    </mx:FormItem>

我的弹出窗口代码是：

XML code

package com.jrosion.comas{    import flash.display.DisplayObject;    import flash.external.ExternalInterface;        import mx.core.Application;    import mx.core.IFlexDisplayObject;    import mx.effects.Blur;    import mx.effects.Zoom;    import mx.events.TweenEvent;    import mx.managers.PopUpManager;      public class PopUpEffect    {             public function PopUpEffect(){}             public static function Show(control:IFlexDisplayObject, parent:DisplayObject, modal:Boolean=true):void           {               var mShowEffect:Zoom = new Zoom();            mShowEffect.zoomWidthTo=1;               mShowEffect.zoomHeightFrom=0;               mShowEffect.zoomWidthFrom=0;               mShowEffect.duration=600;             mShowEffect.target=control;            mShowEffect.reverse();            mShowEffect.play();            PopUpManager.addPopUp(control, DisplayObject(Application.application), modal);            control.x = (Application.application.width - control.width) / 2;            control.y = (Application.application.height - control.height) / 2;            PopUpManager.centerPopUp(control);        }             public static function Hide(control:IFlexDisplayObject):void           {               var mHideEffect:Blur = new Blur();               mHideEffect.blurXFrom=0;               mHideEffect.blurYFrom=0;               mHideEffect.blurXTo=255;               mHideEffect.blurYTo=255;               mHideEffect.duration=300;               mHideEffect.target=control;               mHideEffect.play();            mHideEffect.addEventListener(TweenEvent.TWEEN_END, function():void                {                       PopUpManager.removePopUp(control);                   });           }       }   }

[解决办法]
弹出窗口creationComplete后再加载数据
[解决办法]
<mx:ComboBox id="parentNode" dataProvider="{departments}" labelFunction="disDepName" labelField="name" />

用了labelFunction就不用labelField了

[解决办法]
按你说的写了个例子测试了下:
PopUpWin.xml

JScript code

<?xml version="1.0" encoding="utf-8"?><mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"     width="400" height="300" title="测试PopUpEffect" showCloseButton="true"     creationComplete="init()" fontSize="12" close="closeWin()">     <mx:Script>         <![CDATA[             import mx.collections.ArrayCollection;             [Bindable]             private var departments:ArrayCollection = new ArrayCollection([                 {code:'a',name : 'deptA'},                 {code:'b',name:'deptB'},                 {code:'c',name:'deptC'}             ]);             //             private function closeWin():void{                 PopUpEffect.Hide(this);             }         ]]>     </mx:Script>    <mx:FormItem label="父节点：" required="true">        <mx:ComboBox id="parentNode" dataProvider="{departments}" labelField="name" />    </mx:FormItem>    <mx:ControlBar horizontalAlign="right">        <mx:Button id="btClose" label="关闭" click="closeWin()"/>    </mx:ControlBar></mx:TitleWindow>

我跟5楼一样，我做例子的时候，为了模拟动态查询的时差，用timer迟一些给数据，也没出现那种效果。
要么建议楼主把Flex SDK升级下试试。
