Comment 2 Tomas Pavek 2013-08-14 16:36:49 UTC 
The exception indicates that the container created for the GridBagLayout designer actually did not have GridBagLayout set. I have no idea how that could happen. Maybe some custom container with some container delegate magic? There's no preceding error in the log file (would expect e.g. some problem cloning the container for the grid designer). Please reopen if you can find steps to reproduce.
