Comment 6 Peter Zavadsky 2002-03-28 14:50:12 UTC 
Problem is similar like in the case of #21946, there are accessed GUI
compoenents outside of AWT thread, what in this case led to deadlock.

Fix makes it sure also this part is planned to AWT thread.

Note:
There were a couple of bugs related to same problem, therefore is
necessary to write the test ensuring these kind of problems are
solved. see task #21947.

Patch for orion_fcs (it contains fixes for both #21921 and #21946)
Comment 9 David Simonek 2002-03-28 15:31:32 UTC 
reviewed, ok, diff looks good. Reordering replanned to AWT through
DeferredPerformer, which assures that reorder will come after all
components are added into container, which is what we want.
Comment 10 Marian Mirilovic 2002-03-28 16:03:38 UTC 
Patch - verified.

I played with this patch last 30 minutes and I didn't see any
deadlocks.
