Hi all, I have a python script (see below) which returns a list of the parents of an object so that I can build a breadcrumbs trail across the top of my page. This works fine - except when adding an instance of any of my ZClasses using http://myserver.com/EMDB/Groups/Group_20/Project_35/Labnotebook/manage_addPr oduct/EMDB/Labnotebook_factory I get the following error message: Error type: Unauthorized Error value: Access denied for 'EM Database' because its container, /EMDB/Groups/Group_20/Project_35/Labnotebook, has no security assertions. If I try to add without the breadcrumbs in my standard html header - it works fine Can anyone help me out here?
