> mx.controls::SWFLoader/contentHolder_addedHandler()[E:\dev\4.x\frameworks\projects\framework\src\mx\controls\SWFLoader.as:2543]

> [/RTE]
> Error #1009 has occurred:
> [Fault] exception, information=TypeError: Error #1009: Cannot access a
> property or method of a null object reference.

> 474409377, class='flash.events::Event']) at <null>:0
> --
> I suspect that in mx:SWFLoader.unloadContent(), contentHolder is not a Loader
> and the contentHolder_addedHandler listener is not removed. Hence if
> Event.ADDED is dispatched when contentHolder is null, the last line in
> contentHolder_addedHandler causes the #1009 error.
> This was working at Flex 4 Beta 1.
> Workaround:
> Since we're using embedded images in this case, we can use s:BitmapImage
> instead of mx:Image (which subclasses SWFLoader):
> <s:BitmapImage id="sample1" />
