Products that use ZClasses need to be imported from Control_Panel/Products (The error you got is normal when you try to import a ZClass product from some place other than the control panel.)

Hi. What does it mean when a newly installed object fails to show up in the "Available Objects" list of the Zope Contents page? I have been trying to install Ken Manheimer's Tracker. I put the TrackerBase object in the lib/python/Products, copied Tracker.zexp to the import directory, made a symlink from Extensions/TrackerMethods.py to lib/python/Products/TrackerBase/TrackerMethods.py, and restarted zope. The TrackerBase object does not show up in the "Available Objects" list, and attempting to import Tracker.zexp gives the error "The object Tracker does not support this operation" along with an uninformative-looking backtrace. On the other hand, the TrackerBase did turn up when I did a "Find."
