问题描述：连续使用PopUpManager弹出新窗口数次后，出现“RangeError: Error #2006: 提供的索引超出范围”错误。

解决方法：弹出部分代码修改为

if(sd.parent==null){ PopUpManager.addPopUp(sd, this, true); }else{ PopUpManager.bringToFront(sd); }

其中sd为弹出窗口组件。

问题出现原因：PopUpManager不能很好的控制添加到其内控件的层级。每次都addPopUp 到最顶层，程序也不知道到底要增加到多少，最多三次就出现这个错误（—。— FLEX bug不少啊）。

控制台报错：无限递归调用——main.js:27 RangeError: Maximum call stack size exceeded

RangeError: Maximum call stack size exceeded` 是一个在 JavaScript 中常见的错误，它表明你的程序中存在无限递归调用或者嵌套的调用层次太深，导致调用栈溢出。调用栈是 JavaScript 用来跟踪当前执行函数的内部堆栈，当这个栈达到其预设的最大容量时，就会抛出这个错误。在你提供的错误信息 `main.js:27` 中，`main.js` 是出错的文件名，`27` 是出错代码所在的行号。

如果你使用了PopUpManager.addPopUp添加弹出控件，出现以下错误 RangeError: Error #2006: 提供的索引超出范围 那么其中的原因是PopUpManager不能很好的控制添加到其内控件的层级。每次都addPopUp 到最顶层，程序 也不知道到底要增加到多少，最多三次（我我试验过的，不知道其他的情况）就出现这个错误。 解决方法是代码如下列所写，想信你一看...

      系统需要用JMS来实现消息提醒，类似于QQ的消息提醒，最初只是一个简单的文件扫描，弹出窗口是一个组件A，每此都实例化一个新的A弹出，点击A上的查看按钮后移除组件A。但是二期定制查询也用到了消息，这就需要连续弹出组件A，弹出三次组件A后flex就报下面的异常：   RangeError: Error #2006: 提供的索引超出范围。 at flash.display::Disp...
