Maybe you can test if getFocus() is contained within and move focus beforehand

Subject: [flexcoders] Re: UIMovieClip shows nondeterministic behaviour
Hi Alex,
yes indeed, the object gets removed but i don't know how to identify which
component
actually is the source of the problem.
What gets removed is a composite of components, each skind with a UIMovieClip.
Sometimes, when i want to remove it, the error occours. but it is the
sometimes, that bugs
me.
Best regards, Florian

I have a pretty big application. The app uses various in Flash created
components.
Everything works fine untill some certain point, which varies from test to
test. At some point, my app crashes with a typeerror:
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

The stacktrace is not that helpfull to me... seems a similar problem like:
http://bugs.adobe.com/jira/browse/SDK-13182
The error is not reproduceable/hard to reproduce, since it happens randomly
when
trying to remove some displayobjects...
Any infos or help would be appreciated!
