    Cayenne always requires a reverse *Db* relationship, but not *Obj*
    relationship. So from the object model perspective you are OK: your Java
    classes will only have the required methods, and no artificial "reverse"
    properties are needed.

    This is just the way inner working is done in Cayenne. In the future we
    will most likely implement DbRelationships to be bidirectional by
    definition to avoid such confusion.

    Thanks for the compliment. Doing our best :-)
