Hello, i have the following problem: I created a ZClass within a Product, strictly following the "Zope Developer's Guide (ZDG)". The Product is as simple as the CDProduct mentioned in the ZDG. The Product works for me, the superuser. I can add Instances, manage properties, delete instances and so on. The Product is called "LinkProduct", the ZClass "LinkClass", meta_type "Link". Next i created new folder, a new user account in it, defined a role and added the user to the role. I gave the permisson to "Add Documents, Images, and Files" and the user (role) is able to add these. Now the problem: I gave the Permission "Add Links" to the user (role) and the user can chosse my Class from the "Available Objects" Selection. If he clicks "Add", the Browser ask for a password and the error follwing exception occurs: Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access this resource. Username and password are not correct. Traceback (innermost last): File /usr/local/Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 151, in publish File /usr/local/Zope-2.1.2-src/lib/python/ZPublisher/BaseRequest.py, line 442, in traverse File /usr/local/Zope-2.1.2-src/lib/python/ZPublisher/HTTPResponse.py, line 551, in unauthorized Unauthorized: (see above) Can anyone help me? What goes wrong and which permission is missing? Thanks for your help. Please note that the Product seems to work, also giving permissions to the user (role) works: With "Add External Methods" the user can add them. Why can't he add my Product with the "Add Links" permission? Jan P.S.: I tried my running Zope 2.0.1 and a new 2.1.2 installation, both from source with Linux 2.2.12 and Python 1.5.2 -- Dipl.-Inform.
