Hi all, I'm trying to determine whether this is a Zope problem or a bug in mxDateTime: Whenever Zope reloads the module with my tiny and dumb ExternalMethod "splitDate()", which imports mxDateTime, I get the following error: <error> Error Type: TypeError Error Value: copy_reg is not intended for use with classes ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File /var/lib/Zope-2.4.0-linux2-x86/lib/python/DocumentTemplate/DT_Util.py, line 204, in eval (Object: REQUEST.set('m',utils.splitDate(odd))) (Info: utils) File <string>, line 2, in f (Object: guarded_getattr) File /var/lib/Zope-2.4.0-linux2-x86/lib/python/Products/ExternalMethod/ExternalMet hod.py, line 229, in __call__ (Object: splitDate) File /var/lib/Zope-2.4.0-linux2-x86/lib/python/Products/ExternalMethod/ExternalMet hod.py, line 207, in getFunction (Object: splitDate) File /var/lib/Zope-2.4.0-linux2-x86/lib/python/App/Extensions.py, line 167, in getObject (Info: ('/var/lib/Zope-2.4.0-linux2-x86/Extensions/BELOG.py', 'BELOG')) File /var/lib/Zope-2.4.0-linux2-x86/Extensions/BELOG.py, line 7, in ? File /usr/lib/python2.1/site-packages/mx/DateTime/__init__.py, line 7, in ?

The part in mx/DateTime/__init__.py reads: <code> class modinit: ### Register the two types import copy_reg def pickle_DateTime(d): return _DT,(d.absdate,d.abstime) def pickle_DateTimeDelta(d): return _DTD,(d.seconds,) copy_reg.pickle(DateTimeType, pickle_DateTime, _DT) copy_reg.pickle(DateTimeDeltaType, pickle_DateTimeDelta, _DTD) </code> I'm using: Zope 2.4.0 (binary release, python 2.1, linux2-x86), python 2.1.1, linux2) Python 2.1.1 (#1, Aug 30 2001, 09:43:56) [GCC 2.95.3 20010315 (SuSE)] on linux2 Thanks, H. -- Heiko Stoermer Project Manager Login & Solutions AG heiko.stoermer@login-solutions.de http://www.login-solutions.de
