Thank you for pointing this out.  If I go into the  DTML method I created in
the "methods" folder of my ZClass and change the Proxy Role to Manager, it
works just like it should!

I have some questions about this, if the object is already in the catalog
and just needs to be updated.  Would I still use this method, or would this
create an additional object in the database?

I found the following python script which mentions how to use the
catalog_object method:

http://www.zopera.org/Members/Caro07/updatecatalog

request = context.REQUEST
catalog = context.Catalog

myobject = getattr (context, id)
catalog.catalog_object (myobject, id)

However, when I try using this, I receive an error saying that "global name
'id' is not defined"

Do you have any suggestions on how to I might implement this correctly?

Thanks!
