Hi, I sporadically receive the exception shown below or simular. This
is in development mode. I'm not sure about production mode. Is there a
way to catch all exceptions in GWT?
I don't see any of my lines in the exception and wonder what I can do
to avoid this in the future.
I use GWT 2.0.4, OS X 10.6.4 and Safari 5.0.2.
