Description

I'm not sure where this belongs. Doesnt look like a problem with mx:PopUpButton. Looks more like something specific to either SystemManager or the flex.core.Application class.

Steps to reproduce:
1. Compile and run bad.mxml (or view attached bad.swf).
2. Open teh PopUpMenuButton control's menu and select an item (or just close the pop up menu).

Actual Results:
RTE:
ReferenceError: Error #1069: Property rawChildren not found on bad and there is no default value.
at mx.managers::SystemManager/mouseDownHandler()[E:\dev\trunk\frameworks\projects\framework\src\mx\managers\SystemManager.as:3407]

Expected Results:
No RTE.

Workaround (if any):
Use <mx:Application> tag instead of Gumbo <Application> tag.
