Jeff -
I saw the bug you referenced in JIRA when i searched, but I decided to
add my bug report anyway because that existing one was marked as "closed".

Scott,
There seems to be a variety of cirumstances where the behavior can be
seen. Here's a bug entry for the item already:
http://bugs.adobe.com/jira/browse/SDK-14470
<http://bugs.adobe.com/jira/browse/SDK-14470>
I was able to make it happen by have a PopUpButton instance inside a
Panel inside a Module.
This defintely must be resolved before Flex 3 is released. Can't have
something as generic as a PopUpButton failing and requiring a
workaround. Yes it is true that there were other issues with the
PopUpButotn component, however right now this component is
effectively broken and I would hope it doesn't assume the category of
a 'known issue' when Flex 3 is formally released.

I agree - nulling the _popUp property seems like a hack. There
doesn't seem to be a
logical link between removing a PopUpButton from the stage and
nulling its _popUp
property. Why would a developer expect to have to re-set the
_popUp property of a
previously functioning PopUpButton every time its added back to
the stage? If there's code
elsewhere that requires this hack then it sounds like that code
that should be fixed.
Covering it up only leads to more problems later on.
Scott, have you filed a bug for this?
