[Zope-CMF] Custom metadata editing

[Troy Farrell]

Good day/evening/morning/etc.

I cannot seem to figure out how to edit the custom metadata elements 
that the portal_metadata tool allows me to create.  I've created an 
element that I cannot reach called 'ConferenceYear'.  I've tried

item.editMetaData({'ConferenceYear':'2003'})
item.manage_editProperties({'ConferenceYear':'2003'})

Do you have any ideas before I start hacking CMF sources?

I'd search cmf.zope.org except that ZEO is acting up and the search 
isn't working...

Thanks.
Troy
