[Pyobjc-dev] Formal protocol and extra methods

[Johan R. <joh...@gm...>]

I try to implement a format protocol in python.  Everything works fine
as long as my class only
has methods that are defined by the protocol.  When I extend my class
with something else,
I get an error:

    class MasterListScopeBar(MGScopeBarController):
objc.internal_error: PyObjCClass_BuildClass: Cannot fetch key in keylist

For example, if I add a awakeFromNib method this happens.

Why is this?
