One of my Python Products is not working. It fails with the above error when trying to "from Globals import DTMLFile" File "/home/local/opt/Zope-2.4.3/lib/python/OFS/Application.py", line 563, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/zopeinstancehome/Products/XXX/__init__.py", line 2, in ? from XXX import XXX manage_addSNPSetForm, manage_addSNPSet File "/usr/local/zopeinstancehome/Products/XXX/XXX.py", line 11, in ? import YYY File "/usr/local/zopeinstancehome/Products/XXX/YYY.py", line 13, in ? from Globals import DTMLFile, HTMLFile, InitializeClass File "/home/local/opt/Zope-2.4.3/lib/python/Globals.py", line 95, in ? from Persistence import Persistent, PersistentMapping ImportError: cannot import name Persistent Other products which do exactly the same thing are working fine. This product was also working earlier today. I've tried the "import ZODB" trick, but it doesn't help. Any ideas? Thanks, John Ziniti
