    Depends on what you are trying to accomplish. Overriding
    CayenneDataObject.setPersistenceState(..) is useful for a number of
    things, but if you want to make modifications that need to be
    committed to the database, validateFor* should be a more appropriate
    place.

    I don't know the details of what you are trying to do, but there is
    nothing wrong with such approach too.
