Target milestone -> 3.3 I think this has been fixed under different number. Trying to find the corresponding report and checking the code. 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. *** Issue 14983 has been marked as a duplicate of this issue. *** This was fixed with other changes in NFT wizard. Works for me in dev 20010925. Resolved for 3.4.x or earlier, no new info since then -> verified Resolved for 3.4.x or earlier, no new info since then -> closing. |
