    I also tend to think that less is better. This discussion thread was a
    nice brainstorming on the callbacks use patterns. So we've played with
    a few things and now I am fine if we go a full circle to the minimal
    change suggested earlier, and don't worry about JPA users, extra
    delete callbacks, or symmetry between callback types (in many respects
    there's little symmetry if you look at the object lifecycle - http://cayenne.apache.org/doc/persistent-object-lifecycle.html)
    .

    So here is the change I am going to make:

    1. Call "prePersist" before commit
    2. Introduce "postAdd" instead of current "prePersist".

    This change is minimal and is not incompatible with other ideas.
    Objections?
