I didn't find any place where you create your __ls_demanded_links-list. So - how do you expevct it to be found, __-semantics or not? But I _did_ find a self.__ls_demandedLinks. So I guess you got confused in your variable names. After changing that, I got some other errors. So basically this boils down to some simple spelling errors. You migt want to think about using pychecker or pylint or both, and a auto-completion-capable editor like eric or (x)emacs. Diez -- http://mail.python.org/mailman/listinfo/python-list
