Comment 1 Jan Chalupa 2001-05-06 08:14:28 UTC 
Target milestone -> 3.3
Comment 2 David Strupl 2001-08-13 14:45:15 UTC 
I think this has been fixed under different number. Trying to find the
corresponding report and checking the code.
Comment 3 David Strupl 2001-08-13 15:36:51 UTC 
The updateState method is called from a non-AWT thread and it
manipulates living AWT hierarchy. This is definitely wrong. But be
extremely careful because this method is synchronized on this and
moreover there is a hack allowing to throw IllegalStateExceptions from
certaing methods. Please preserve the behaviour of returning back to
previous panel after catching the IllegalStateExceptions.
Assigning to Jano since he wrote most of the updateState method.
