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... Any hints... Sascha PS: I know ZClasses, but I want to use pure python for comfort reasons... -- .-> Sascha Matzke - sascha@bespin.de - http://www.bespin.de -. | Das Kapital ist die Flamme, der Faschismus das Benzin | | Anarchist Academy | `-- On this earth for 24 years, 3 days <----------------'
