Hi, I noticed that zope.app.file.File does not inherit from zope.app.container.contained.Contained. This does not stop a file from, e.g., getting added to a folder (and the File type does appear in the ZMI add menu). It does, however, stop you from getting at the File's parent. Currently, File cannot be used as a proper content type, though it looks like it is supposed to be one. IMO File should inherit from Contained; am I wrong for some reason, or is this an issue that should be fixed? If the latter, I'd look into it. -- Thomas
