I am building a small application based on the "Build a simple ZClass (CatalogAware, non-default Catalog, Folderish)" how-to, but entirely using ZPT - I don't want to learn dtml! The objectManager constructor works fine with the lines as follows: instance = container.Directory.createInObjectManager(request['id'], request) instance.manage_addDTMLMethod('index_html','',instance.def_index) When I try to replace the dtml with: instance.manage_addProduct['ZopePageTemplate'].manage_addZopePageTemplate('memberIndex.pt') I get:Error Type: AttributeError Error Value: ZopePageTemplate when creating an instance of the ObjectManager ZClass. I have read many of the how-tos available, including the DTML to ZPT Conversions and hacked a lot but I can't find my error. Can someone help me please? Regards
