[Zope] Product unable to be called

[Zachery Bir]

A coworker and I developed a product for our customers handling 
minimal content management, and the mangement side works pretty 
flawlessly. We can add new content items, edit them, etc. But now, 
when we go to publish them, I'm getting errors about __call__ not 
being found. We used the Boring Product tutorial as our guide, and 
it never mentions making a __call__ method in the Product's Class 
definition, so we never did. I see that many other Objects use 
__call__, but I'm not sure where to proceed with ours.

Any pointers?
