I was able to eliminate a fatal error when loading HTMLDocument 0.2 in Zope 2.4.0b3 by commenting # __implements__ = IHTMLDocument # XXX ??? in HTMLDocument.py The alternative is to have Util.py check "interfaces" before trying to iterate over it. I don't know enough about it to judge where the fix should go. --kyler ------ 2001-07-07T19:26:34 PROBLEM(100) Init Ambiguous name for method of Products.HTMLDocument.HTMLDocument.HTMLDocument: "manage_editForm" != "manage" ------ 2001-07-07T19:26:34 PROBLEM(100) Init Ambiguous name for method of Products.HTMLDocument.HTMLDocument.HTMLDocument: "manage_editForm" != "manage_main" ------ 2001-07-07T19:26:34 PROBLEM(100) Init Ambiguous name for method of Products.HTMLDocument.HTMLDocument.HTMLDocument: "manage_editForm" != "manage_main" ------ 2001-07-07T19:26:34 PROBLEM(100) Init Ambiguous name for method of Products.HTMLDocument.HTMLDocument.HTMLDocument: "manage_editForm" != "manage" initializing PurdueUserFolder ------ 2001-07-07T19:26:41 ERROR(200) Zope Couldn't install HTMLDocument Traceback (innermost last): File /home/www/Zope.6/src/Zope-2.4.0b3-src/lib/python/OFS/Application.py, line 657, in install_product (Object: ApplicationDefaultPermissions) (Info: HTMLDocument) File /var/www/Zope.6/Zope/lib/python/Products/HTMLDocument/__init__.py, line 20, in initialize File /home/www/Zope.6/src/Zope-2.4.0b3-src/lib/python/App/ProductContext.py, line 233, in registerClass File /home/www/Zope.6/src/Zope-2.4.0b3-src/lib/python/Interface/Util.py, line 66, in instancesOfObjectImplements (Object: HTMLDocument) File /home/www/Zope.6/src/Zope-2.4.0b3-src/lib/python/Interface/Util.py, line 72, in _wi (Object: IHTMLDocument) TypeError: loop over non-sequence
