Re: [abbot-users] JTree Support

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I test in Linux. Also has this problem. When I click I don't know which
part of Costello code is involved. So I can only add a breakpoint before
the exception.

The following information is achieved with "ctrl+L". May it help.
