Hia Zopers, I'm totally confused and I couldn't figure it out in 2 working days so here it is: I have a Zope Product that makes use of different nested classes. When I create an instance of this product I always get an "unauthorized" error when clicking the instance in the management interface (=accessing <instance>/manage) even if I am logged in as a manager or superuser. The strange thing is that for example <instance>/manage_access works fine for me. I tried all stuph with permissions, switched acquisition on and off, added 'manage' to my permission tuple, gave everyone the right to view management-screens and so on. The error message says only "unauthorized" and the traceback points to Management.py Any Ideas? (btw: it worked fine in 2.1.6) thanx a lot philipp dunkel, zReal Productions, The Hague _______________________________________________ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
