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 )
