Is there a way to make the generated GUI code from IDEA visible?

I have made an extremely simple project in IntelliJ's IDEA, basically just a form with a JToolBar containing a JButton, and when I try to launch it, I get an NPE in form.$$$setupUI$$$ - but no such thing is reflected in the actual form.java, so I have no way to debug it or track down the bug.

Is there a way to make IDEA show (and maybe even let me change) the 'magically' generated code ?
