Summary: problem with Session.ModelObjects() ERwin COM API

Initial Comment:
I'm hoping this is a coding error on my part, but I've
encountered a problem with interface that I cannot
understand. I try to use pywin32 (build 210 for Python 2.4) on WinXP for access to AllFusion ERwin Data Modeler 7.1 (Computer Associates) via ERwin COM API:

------------------------- begin erwin.py
import win32com.client
ERwin = win32com.client.dynamic.Dispatch('AllFusionERwin.SCAPI')
PersistenceUnit = ERwin.PersistenceUnits.Add(r'D:\s\model.erwin')
Session = ERwin.Sessions.Add()
ModelSet = PersistenceUnit.ModelSet()
Session.Open(ModelSet)
ModelObjects = Session.ModelObjects()
------------------------- end erwin.py

Traceback (most recent call last):
  File "D:\Project\erwin\src\root\nested\erwin.py", line 7, in ?
    ModelObjects = Session.ModelObjects()
  File "C:\Python24\Lib\site-packages\win32com\client\dynamic.py", line 172, in __call__
    return self._get_good_object_(self._oleobj_.Invoke(*allArgs),self._olerepr_.defaultDispatchName,None)
pywintypes.com_error: (-2147352562, '\xcd\xe5\xe4\xee\xef\xf3\xf1\xf2\xe8\xec\xee\xe5 \xf7\xe8\xf1\xeb\xee \xef\xe0\xf0\xe0\xec\xe5\xf2\xf0\xee\xe2.', None, None)



Any insight into this problem would be most appreciated.

Regards,
Denis V. Komarov
