    Cayenne, by default, doesn't map keys from the DbEntity (database
    definition) to the ObjEntity (Java definition), but you can go into
    the ObjEntity and add them and it should be fine. After you do that,
    just call the set/get methods for the keys to set/get them. If you
    set a key on a new object before you commitChanges(), Cayenne will use
    your key instead of trying to generate one.
