I get the same errors when I use Override/Implement methods. It will generate multiple "An error has occurred" popups and then display a screen where "object" will show correctly, but other superclasses will just appear as a name with a series of blank check boxes following it. If I select those checkboxes it will produce a set of overriding methods, but none of them will take arguments of any kind. Multiple copies of the NullPointerException will then appear in my console, one for every dialogue I had to dismiss.

System: MacOS X
Eclipse: 3.2.2
PyDev: 1.3.6
