[Zope] - how to validate access to an object..

[Simon Michael]

Thank you for Zope. Yea! It is a thing of beauty!

I have created a simple file repository with an explorer-style interface,
search form and access control. It's like a much-simplified version of the
management UI, whose code I have been staring at. This has helped a lot, as
have the mailing list archives.

My search form uses an external method which is similar to
FindSupport.PrincipiaFind(). It has one problem - it lists files for which
the user does not have view permission.

The tree tag handles this well and I want to add a similar validate() check
to my find method, but I cannot find the right magic! I am confused about
the arguments and have found debugging difficult. Eg I cannot step into the
external method.

Any tips would be most welcome..
