Zopists, When I start up Zope with my .zexp of my ZClass based product from 2.0 I get this message. 2000-10-27T23:36:46 ERROR(200) Zope Couldn't install Staff Traceback (innermost last): File /home/jason/Zope-2.2.0/lib/python/OFS/Application.py, line 478, in install_products (Object: ApplicationDefaultPermissions) (Info: Staff) File /home/jason/Zope-2.2.0/lib/python/App/Product.py, line 435, in initializeProduct (Object: Products.Staff) File /home/jason/Zope-2.2.0/lib/python/ZODB/ExportImport.py, line 208, in importFile SystemError: Failed to import class _ZClass_for_CatalogAware from module Products.ZCatalog Everything works, I can get my data in and out. Only I get some strange behavior from the CatalogAware zclasses (they don't pay attention to the "sort" attribute of searches for example) Is there anything I can do to make the move to 2.2.2 100%? Put a phantom class in the ZCatalog folder? All my best, Jason Spisak
