Re: A possible critical bug for gwt-fabridge.
Hi Jihong,
Perhaps a more appropriate place to report this gwt-fabridge bug would be on
the project Issue Tracker. I'm sure the developers behind the project would
be happy to be notified about a potentially critical issue.
http://code.google.com/p/gwt-fabridge/issues/list
Hope that helps,

Re: A possible critical bug for gwt-fabridge.
You missed my point there. I guess I should have said I don't know OR
care what gwt-fabridge is, but if you want help with it, you might as
on a forum that is relevant to it?

Re: A possible critical bug for gwt-fabridge.
I don't know what gwt-fabridge is, but maybe that project has it's own

get much response here.
