I have a Zclass which inherits from ObjectManager and have a property sheet set on the ZClass. I created a view associated with an index_html method that is defined for the ZClass. When I try to access the view, I get a pop up window asking for authorization (which always fails) and then when I cancel the authorization dialog I get Error Type: Unauthorized Error Value: You are not allowed to access title_or_id in this context Here is index_html: <dtml-var standard_html_header> This is a test <dtml-var standard_html_footer> The problem is coming from the standard_html_header, because if I take out the header and footer, I display 'This is a test' as plain text without error. I as assuming that my ZClass should have inherited title_or_id and that something is not working right. Can anyone advise? I don't think this is really an authorization problem because I am logged in as a user that has Manager and Owner privileges in root. Thanks, John Hunter Zope-2.5.2
