Wonderful! Thank you *so* much for your help--it worked like a charm. --- Chris -----Original Message----- From: Hannu Krosing [mailto:hannu@tm.ee] Sent: Thursday, February 24, 2000 5:30 PM To: Carlson, Christopher W.

Following your recommendation, I get the following:
Zope has encountered an error while publishing this resource.
Error Type: AttributeError Error Value: __getslice__
after I added the __getslice__ operator to lib/python/Shared/DC/ZRDB/Results.py it started working both the def __getslice__(... and self._brains=brains in __init__ are needed the start of class Results would look like this: class Results: """Class for providing a nice interface to DBI result data """ _index=None def __getslice__(self,start_index,end_index): return Results((self.__items__,self._data[start_index:end_index]), self._brains, self._parent) def __init__(self,(items,data),brains=NoBrains, parent=None): self._data=data self.__items__=items self._parent=parent self._brains=brains self._names=names=[] There could be better solutions, but if there are none, I would urge the DC folks to consider adding something similar to Zope. ------------------ Hannu
