Did this ever get resolved? I had similiar problem with a custom Product extending Folder. Noticed when I commented the following lines of code, the error went away: #security.setDefaultAccess("deny") #__roles__ = () ------------------------------------------------------ Thanks for the response Dieter, On 5 Feb 2004, at 18:51, Dieter Maurer wrote:

Looks like "RESPONSE" is "None".

I do not see how this can happen...

Exactly! - this is why I said I'd never seen this before. It's a 2.6.1 Data.fs that's been dropped into a stock 2.7.0rc2 release and I get this error. I have no idea why this is happening, so I was hoping that it was an artifact of the 2.7.0rc2 release itself.

Probably, I would start debugging.

Quite likely, but I have *no* idea where to start with this. All the modules mentioned in the trackback are Zope supplied ones, not third party ones, so I'd assumed it might be the core software.
