I am sorry, I am not able to reproduce this issue. The exception shows that 'designSupport' variable has null value. 
Unfortunately, it is not clear how this can happen. The variable is initialized by 'FormEditor.getBindingSupport
(bindingComponent.getFormModel())' expression that should be always different from null in this context.

Are you still able to reproduce this issue? If so, could you, please, provide exact steps to reproduce? Thank you in 
advance.

I haven't attemted to reproduce this exception. If I recall correctly I had placed a panel on a jframe. I then changed the panel in the gui builder so that it used 
the AppFramework. This provoked the gui builder to fail during load of the jframe form.
