New Revision: 5333

Modified:
   base/trunk/mpulsweb/model/case.py
Log:
Port Case model methods getHashFields and is_hashable from WASKU to
mpulsweb. The getHashFields method is only a stub here which always
raises NotImplementedError, because it cannot be implemented fully in
mpulsweb as it doesn't know how to extract the needed information from
the case. The is_hashable method is copied unchanged from WASKU web
412:2988cbbf9f39, though.
