Trying out an test app, I get the following error: unhandled TypeError "__init__() takes exactly 2 arguments (1 given)" Datei: /usr/local/lib/python2.6/dist-packages/dip/model/meta_model.py, Zeile: 113 I get this error, when I run meta_model.py itself, too. Is it a bug or is something wrong with my settings eg.? Does anybody know? Thanks, Achim
