Comment 1 David Simonek 2001-03-01 14:30:56 UTC 
Reassigning to Marek Slama, my favourite co-worker :-)
Comment 2 mslama 2001-03-02 16:18:04 UTC 
Fixed in SplittedContainerImpl.componentRemoved.
Commented premature call of closeTabbedContainer() - it happened only
when workspace was not active eg. when workspace was deleted.
Comment 3 Robert Dankanin 2001-03-20 14:19:48 UTC 
[NetBeans 3.2 build #8]

verified

Comment 5 David Simonek 2001-03-28 13:26:26 UTC 
Huh, it seems that there is some misunderstanding, because the exception Jiri is
reporting is different from original one and it occured in different situation.
Why didn't you create new bug, Jiri? Please do so, and attach set of steps to
reproduce the problem. Without reproduction, issue is invalid because I will not
be able to do anything with it. Thanx.
Comment 6 Jiri Skrivanek 2001-03-28 14:10:30 UTC 
You are right.
Comment 7 Quality Engineering 2003-07-01 16:28:43 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
