[python-win32] "Property '%s.%s' can not be set" on read/write attribute

[Tim Johnson]

So I'm trying to automate some tasks with SMS, and I've run into a roadblock
when creating new collection membership rules.  The code below is a method
of a Collection object.  It's a rough draft, so don't worry too much about
the top half unless you think it might be screwing something up.  My problem
is that I go to create a new SMS_CollectionRuleDirect object (at the bottom
of the code provided) and I get the following error:

>>> coll.AddMembershipRule(rule)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "H:\p4rootw\lib\ops\sms.py", line 495, in AddMembershipRule
    rule_obj.RuleName = name
  File "C:\Python24\Lib\site-packages\win32com\client\dynamic.py", line 550,
in __setattr__
    raise AttributeError, "Property '%s.%s' can not be set." %
(self._username_, attr)

If you look in the SMS 2003 SDK v3.1 or here (
http://www.microsoft.com/technet/prodtechnol/sms/sms2003/opsguide/ops_854m.mspx?mfr=true)
you can see that the property is indeed Read/Write.  Is there any way to
override this or some workaround that I can use to fix this?  I'm about
ready to start hopping up and down in my office chair like an angry
chimpanzee.





# This is a method of an sms.Collection object.
#
# self.parent.wmi_connection is an object created via wmi.WMI() with the
#   namespace set to
\\server\root\sms\site_S01<file://server/root/sms/site_S01>,

#   and I can retrieve information fine, as well as add/edit Collection,
#   advertisement, and other objects just fine.
#
# self.parent.db_connection is an object created via odbc.odbc(), connected
to the SMS database
