OK, that did the trick! It was a bit counterintuitive
to me at first to have to use low-level data access on
objects that are just fetched from the database, but

I've put a little thing in the CDBI Wiki about this
subject, that hopefully will prevent people like me
asking this question again on the mailinglist.
