Hello,
I want to design 2+ products which all share certain base functionality. So I moved some code into Shared.
Now, when I try to create instances of the products I get the following error:
Error Type: TypeError Error Value: unbound method must be called with class instance 1st argument
I use the following code:
class B(A):
def __init__(self, some, more, parameters): A.__init__(self, some, more)
In my python knowlegde the above should be correct...
This is either caused by ExtensionClass or acquisition, I never bothered to get to the heart of it. It basically confuses the Python interpreter into not seeing the proper class hierarchy, and throwing above tantrum. The solution is simple: call .im_func() to use the unbound method: def __init__(self, some, more, parameters): A.__init__.im_func(self, some, more) -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | T: +31 35 7502100 F: +31 35 7502111 | mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ---------------------------------------------
