I'm still getting a "ComponentLookupError".  I'll just include the  
example I'm trying to make work at the bottom, it's pretty short.   
I'm beginning to think there may be something in your explication  
that I need to understand.

Also, from looking at your example I'm guessing your using the SVN  
version of zope3, is that true and do you happen to know if that  
would make a difference?  I'm currently using Zope-3.2.1.

thanks
