[Zope] CMF: Fields not available in objects found by catalog search?

[Ian Beatty]

Greetings.

I'm constructing a "schedule" page in Plone, following closely the example
of the news page and events slot. It lists information about Events (CMF
Event type) that meet specified criteria (keyword, start date within a
specified range, etc.) by calling container.portal_catalog(). So far, so
good. I can then iterate over the returned result set, call getObject on
each element, and access fields of the object such as "Title" and
"Description".

However, not all of the Event type's fields seem to be available. If I try
to access "location" or "contact_name" (or "Location" or "ContactName"), I
get a KeyError. No such field.

What gives? Why are some fields not accessible? And where can I hack
something to make them accessible?

Thanks,

..Ian Beatty
