Hi. I have upgraded Python 1.52 and Zope 2.2.2 to Python 2.1 and Zope 2.4.1. The Product Photo-0.4.3 and ZPhotoAlbum worked fine with python 1.52 and zope 2.2.2, but now the ZPhotoAlbum ojects appears broken: This object is broken because the unknown product that created it is no longer installed or is installed incorrectly. Please contact the product maintainer for assistance. Also, when I trie to add a ZPhotoAlbum in a folder, I get the following error Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: Catalog addIndex now requires the index type to be resolved prior to adding; create the proper index in the caller. and the error at the end of the message. Does anybody know if the Photo-0.4.3 works with Zope 2.4.1 or how I can fix the problem? I have seen that Photo-0.4.3 is no longer maintained and that there is a new Photo-0.9.2 product. It is possible to upgrade to Photo-0.9.2 with existing photos and zphotoalbums installed with Photo-0.4.3? Thanks. <!-- Traceback (innermost last): File /ma2/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /ma2/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /ma2/zope/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: RoleManager) File /ma2/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /ma2/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: ZPhotoAlbum_add) File /ma2/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: ZPhotoAlbum_add) File /ma2/zope/lib/python/OFS/DTMLMethod.py, line 194, in __call__ (Object: ZPhotoAlbum_add) File /ma2/zope/lib/python/DocumentTemplate/DT_String.py, line 546, in __call__ (Object: ZPhotoAlbum_add) File /ma2/zope/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: ZPhotoAlbum.createInObjectManager(REQUEST['id'], REQUEST)) File /ma2/zope/lib/python/DocumentTemplate/DT_Util.py, line 231, in eval (Object: ZPhotoAlbum.createInObjectManager(REQUEST['id'], REQUEST)) (Info: REQUEST) File <string>, line 2, in f (Object: guarded_getitem) File /ma2/zope/lib/python/ZClasses/ZClass.py, line 522, in createInObjectManager (Object: LockableItem) File /ma2/zope/lib/python/ZPublisher/mapply.py, line 161, in mapply (Object: ZPhotoAlbum) File /ma2/zope/lib/python/Products/Photo/Photo.py, line 595, in __init__ (Object: LockableItem) File /ma2/zope/lib/python/Products/ZCatalog/Catalog.py, line 348, in addIndex TypeError: (see above) -->
