After my question about how to store objects, I blundered across zclasses,
and got some help that pointed me in that direction through email, as well.
I've been learning a lot.

Unfortunately, I'm still having trouble. I've created a
QuoteProduct/QuoteClass combination with person and quotetext as the
properties in the property sheet. I've directed the view to direct toward my
property sheet. Then...

<dtml-var tarheel_header>
<dtml-if "AUTHENTICATED_USER.has_role('Manager',this())">
<dtml-let new_id=get_new_id>
<dtml-call "REQUEST.set('id',new_id)">
</dtml-let>
<dtml-call "REQUEST.set('person','Dave Walker')">
<dtml-call "REQUEST.set('quotetext', 'I have a fat one')">
<dtml-with "manage_addProduct['QuoteProduct']">
<dtml-call "QuoteClass_add(_.None, _, NoRedir=1)">
</dtml-with>
<dtml-else><P>You do not have the proper security to access this resource.
</dtml-if>
<dtml-var tarheel_footer>

This gives me an error:

Zope Error

I played with this thing all night last night, and while I think I'm REALLY
grooving to get some zClasses stuff done, I can't figure out what problem I
have and why, in order to actually start doing.

I'm thinking the key is in the traceback "File <string>, line 0, in ?"
above.  Of course, I'm only guessing.
