Created attachment 229 [details]

Comment 2 Tomas Pavek 2000-11-01 09:52:59 UTC 
Although I could not reproduce the exception, I've changed the code in
FormTopComponent to check formManager is not null - this should fix the problem.
Comment 3 Marian Mirilovic 2000-11-29 15:20:59 UTC 
verified in [main trunk](001123) and [main trunk](nb 78), and boston(1160)
Comment 4 Quality Engineering 2003-06-30 18:27:52 UTC 
Resolved for 3.3.x or earlier, no new info since then -> closing.
