Well, running 2.5.0 on Madrake 8 something, I can tell you that it can work.
So let's see what's going wrong.
Did you rename your ZClass after building it?
Can you post the contents of the add method? (Which, if Zope created it for
you, will be called ZooExhibits_add, and will be located in the
/Control_Panel/Products/Exhibits)
ZClasses aren't (IMHO) quite as evil as some may tell you -- they have their
place for quickly sketching out prototypes or building a simple data object
that will be easier for a client/coworker to modify. If you don't have CVS
running on your server, getting the versioning and history of your objects
is also plus for ZClasses that Python Products wouldn't give. But Python
Products are certainly preferable in many cases. Don't worry, though--there
are lots of snags to consider once you start learning those, too. ;-)
BTW, while the Zope Book is fine, it's gotten a bit out of date. Keep your
paper copy to share with the grandkids, and use the online copy (which is
much more updated) for learning, if you can. You can download it as a PDF.
