Had a fun week recovering from a hack attack. Ok, so DTMLFile.absolute_url() should return its container. Except... DTMLFiles simply don't have absolute_url - their own or inherited. They return an attribute error. I was going to post a feature request to the collector, but if absolute_url on a DTMLFile will return the container, then it's pretty useless.

My product inherit does have implicit acquisition. But HTMLFile doesn't - that's the whole problem. Replacing HTMLFile with DTMLFile solves the problem, as DTMLFile derives from Acquisition.Explicit. Thanks for pointing me in the right direction. P.S Now that aq_parent is working... why can't I do absolute_url() on DTMLFiles :-( -- -- Itai Tavor -- "Je sautille, donc je suis."-- [EMAIL PROTECTED]-- - Kermit the Frog -- -- "What he needs now is understanding... and a confederate victory" -- -- Dr. Jacobi, Twin Peaks -- ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
