If I needed to do that, I guess I would do something like the following:

$artist->remove_from_object_index();
$artist->discard_changes() unless $artist->autoupdate;
$artist = Music::Artist->retrieve($artist->id);

Obviously, you can skip the discard_changes() if you know you definitely
haven't made any changes to the object or if you are using autoupdate mode.
It's only real purpose is to avoid the warning message you get when an
altered, uncommitted CDBI object is DESTROY'ed.

It should be simple enough to devise a generic "refresh" method which does
the above steps (and handles MCPKs!) that you can put in your CDBI base
class. If you do come up with a generic method like that, please add it to
the wiki!

Hope this helps,
