Updating Multiple Tables per Single Root Object

[Mississippi John Hurt]

Hi,
Is there a way to update multiple tables for a single object in ibatis?  Say you have a Auction object with a List of Bid objects. Could you do a mapping for an update similar to a resultmap for select?  I'm thinking that even using ibatis, you'd just use individual updates as if you weren't using ibatis. Is that true?  Thanks.
