Description Jan Stola 2010-10-11 09:58:59 UTC 
Steps to reproduce:
1. Open grid-designer, i.e., invoke Customizer Layout action
   on some container with GridBagLayout
2. Select some component in the grid-designer.
3. Close the grid-designer.
4. Select the same component in the "normal" designer (in main window).
5. Change some property of the component.
   => the following exception is thrown

java.lang.NullPointerException
