Changeset 10635 for main/waeup.kofa/trunk/src/waeup/kofa/university/department.py

Message:

Using attrs_to_fields, which we didn't use in the beginning, makes a lot of problems. Many tests have to be changed and also the batch processor has to be adjusted. Thus it seems to be easier to use to update all department objects with the KofaPluggable? utility.
