So I think the code is ok, but the real question is where do
you run this code? I'm guessing in the Swing thread. If so that
is your problem.
I will repeat that _ALL_ interaction with the DOM _MUST_ be done in
the update manager thread. So getting an element by ID, getting and
most importantly setting attributes _MUST_ be done in the update
manager's thread or bad things will happen.
