[Zope-CMF] You are not allowed to access document_view in this context

[Mark Gibson]

CMF 1.2
Zope 2.5.0

I'm using the Blark threaded discussion product.  This is probably a 
problems specific to this product, but if anyone can point me in the 
right direction, I'd appreciate it.  :)

Blark uses a Document as the basis for 'Articles'.  After it creates the 
Document, it overrides the view method by doing this within the Blark class:

setattr(article,'view',self.document_view)

This seems to work fine when calling the default display method like this:

http://127.0.0.1:9080/BlarkSite/ARTICLE_22121559_1016513192/document_view


However, when I access the article like this:

http://127.0.0.1:9080/BlarkSite/ARTICLE_22121559_1016513192

I get a login prompt, and then the folowing error:

  Error Type: Unauthorized
Error Value: You are not allowed to access document_view in this context

The Blark author said that this problem showed up first in the CMF 1.2 
release.  Anyone have any ideas?

Thanks,
