Hi,
I'm trying to write an external ZClass base class which inherits from CatalogAware and another external ZClass base I've written.
I'm trying to call CatalogAware's manage_afterAdd function from within my new class's manage_afterAdd function, but whenever I try it, I get
Error Type: TypeError Error Value: unbound method must be called with class instance 1st argument
My code looks like this:
class BasicGroup(CatalogAware, LogAware): meta_type = 'BasicGroup'
def manage_afterAdd(self, item, container): CatalogAware.manage_afterAdd(self, item, container) ...
Any ideas?
This is because of ExtenionClasses, the python interpreter is confused about wether or not you are passing in a proper Class instance. To work around this check, call the unbound method: CatalogAware.manage_afterAdd.im_func(self, item, container) -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
