Description

Build 13518

Steps to reproduce:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
creationComplete="handleCC();">

<fx:Script>
<![CDATA[
import mx.managers.PopUpManager;

protected function handleCC():void
{
var app:Application = this;

button.addEventListener(MouseEvent.CLICK,function (event:Event):void

{ PopUpManager.addPopUp(popup,app,true); }

);
}

]]
>
</fx:Script>

<s:Group id="popup" width="100" height="100" />

<s:Button id="button" label="Popup" />

</s:Application>

Actual Results:

RTE: Error: removeChild() is not available in this class. Instead, use removeElement() or modify the skin, if you have one.
at spark.components::Group/removeChild()[E:\dev\trunk\frameworks\projects\spark\src\spark\components\Group.as:1923]
at mx.managers::SystemManager/addChildAt()[E:\dev\trunk\frameworks\projects\framework\src\mx\managers\SystemManager.as:1595]

Expected Results:

No RTE. Perhaps SystemManager could check to see if the parent has removeElement and use that if appropriate.

Workaround (if any):

Add MX container around element to be popped up
Another workaround would be to call removeElement() on the parent of the component before calling addPopUp().
