To be able to actually use the system focus would be an elegant solution, I hope you find it.
If you don't, you can always store a reference to an actual component in an instance var, and set / unset that reference using focus and focusOut event handlers. Not ideal of course, but there it is.

I've not been able to find documentation showing an example of how to use focus. I even put a message in the Adobe LiveDocs, and they responded, "question is too specific. look elsewhere." Has ANYONE ever attempted to catch focus in some manner or form? This should not be that hard but this is becoming a real pain! --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Josh McDonald" <[EMAIL PROTECTED]> wrote: > > Look into the focus events.
