[Zope] strange permission behaviour

[Ingo Assenmacher]

Hi All!

Ok, just in time for my new nervous-breakdown, read this:

I have a ZClass which does have a "render" method.
The render-method collects items from a catalog and calls these objects'
"render" method.
Unfortunately this raises an Unauthorised Error, whenever I do not use the
super-user account.
(Zope has encountered an error while publishing this resource. 

Unauthorized

You are not authorized to access render.

Ok, so I gave the calling Method the proxy-role of the Manager. No change.
The strange thing about it is, and that is what puzzles me, that it works
for another class (which does only slightly different things).

So, what now, hu?

Regards, Ingo.
