Hi, does anybody know why the import of a ZClass-based product does not work? I'm trying to import a product from 2.5.1 into 2.6.1 and always get the traceback below. Any suggestions? Other Products will import fine, just this one fails because it needs a class called 'iclass'. What is this class supposed to do? Thanks in advance, Jens. ------ 2003-03-19T15:36:07 ERROR(200) Zope Couldn't install DocumentPool Traceback (innermost last): File /home/jens/zope/Zope-2.6.1-src/lib/python/OFS/Application.py, line 637, in install_product (Object: Zope) (Info: DocumentPool) File /home/jens/zope/Zope-2.6.1-src/lib/python/App/Product.py, line 512, in initializeProduct (Object: Products.DocumentPool) File /home/jens/zope/Zope-2.6.1-src/lib/python/ZODB/ExportImport.py, line 79, in importFile File /home/jens/zope/Zope-2.6.1-src/lib/python/ZODB/Transaction.py, line 235, in commit File /home/jens/zope/Zope-2.6.1-src/lib/python/ZODB/Transaction.py, line 349, in _commit_objects File /home/jens/zope/Zope-2.6.1-src/lib/python/ZODB/Connection.py, line 286, in commit File /home/jens/zope/Zope-2.6.1-src/lib/python/ZODB/ExportImport.py, line 147, in _importDuringCommit ImportError: No module named iclass
