ExtendedPathIndex doesn't need fixing, but we need to stop using it. It's done to support navigation trees from the catalog, but navigation should not be done via the same catalog as you do other things, but a dedicated tool. That would simplify and speed things up a lot. But OK, that's off-topic. -- Lennart Regebro: Zope and Plone consulting. http://www.colliberty.com/ +33 661 58 14 64 _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
