Hi, When saving a new model object that has child objects (corresponding to a child table), activerecord cleverly does the save as an implicit transaction and saves the model object and the children objects. However, after reading the model object from the database and updating it and it''s children, activerecord does not do an implict transaction when saving the model object. The modified object does get saved but the modified children do not get saved. Why not? Major pain for my current application. Thanks, Peter
