Greetings. I've created a package in Python with some basic classes. They work in the ZMI, except for the fact that the ZMI paste and rename functionality fails with the message "The object xxx does not support this operation." I've dug into the source code for standard types ('OFS.Folder', 'OFS.SimpleItem', etc.) and discovered some tantalizing bits (such as 'manage_renameObject' in 'OFS.CopySupport'), but I can't figure out how to put it together to make my classes renameable and pasteable. I'm rather surprised that behavior doesn't come automatically when inheriting from the standard base classes. One of my folderish classes subclasses the following bases: OFS.ObjectManager.ObjectManager Products.ZCatalog.CatalogPathAwareness.CatalogAware OFS.PropertyManager.PropertyManager OFS.SimpleItem.SimpleItem Am I not inheriting from the proper set of base classes? Is there an easier way? According to the ZDG (2.4 edition, vs. my Zope 2.7), OFS.SimpleItem.Item (subclassed by OFS.SimpleItem.SimpleItem) is supposed to provide cut-and-paste functionality. So, how might I be breaking it?
