Comment 2 MackSix 2012-03-19 18:59:31 UTC

I had just checked "Visualize Additional Layout Information" in Options>>Java>>GUI Builder. Then I opened a new project (with a form). I was closing some Java source files in the editor for a project already opened (that had a form) and this NullPointerException occurred. 

I can't reproduce it now.
