Hi, I was following the 'Howto build a simple ZClass' howto. I didn't change anything with permissions. When this constructor didn't work, I copied and pasted a Python Script constructor from the HOWTO, which is appearantly what Zope 2.6 generates. I renamed the original constructor, created a new Python Script the constructor name, and copied the script from the webpage. That worked, without changing any permissions, and created for me the new ZClass instance. It even created the new ZCatalog instance inside, as it was supposed to. So the constructor code was definately executed, no errors, no permissions changed for anything. Does that help, or does that make it a bigger problem?

Still leaves me with the default DTML Constructor Method for a ZClass not working. The traceback is: ... NameError ... line 61, in render (Object: tbEntry.createInObjectManager(REQUEST['id'], REQUEST)) File C:\Program Files\ZopeSite\lib\python\DocumentTemplate\DT_Util.py, line 159, in eval (Object: tbEntry.createInObjectManager(REQUEST['id'], REQUEST)) (Info: REQUEST) File <string>, line 2, in f NameError: global name 'tbEntry' is not defined Are you sure, the user has the right to create "tbEntry" instances.

Zope sometimes converts "Unauthorized" into "KeyError"s (I am astonished that you get a "NameError"). Check the "Permission" tab of your ZClass. It "Create instances" mapped correctly? Dieter
