Hi, are you referring to this Feeds example:
http://dev.karlproject.org/tutorials/t2-contentandcataloging/feedentries.html If that's the case, note that both Feed and FeedEntry inherit from repoze.folder.Folder, which in fact does inherit from Persistent: http://svn.repoze.org/repoze.folder/trunk/repoze/folder/__init__.py So you, see, the feed objects are actually inheriting from Persistent, just not directly. The consequence of not doing so would be that the data would not be saved at all.
