[Zope-DB] Trouble with result objects traversal

[John Coleman]

Should have written back with this sooner...Thanksgiving and all.  :)

Here is my traceback from 
http://server:8080/registrar/schedule/course/crn/10002

Traceback (innermost last):
   Module ZPublisher.Publish, line 89, in publish
   Module ZPublisher.BaseRequest, line 358, in traverse
   Module Shared.DC.ZRDB.DA, line 569, in __getattr__
KeyError: _r

Am I misunderstanding a ZOPE fundamental here?  I am trying something 
explicitly stated to work in The ZOPE Book...

Thanks again,

John
