    Hi Ronald!

    What version of Cayenne are you using? Cannot say for sure without the code
    causing the exception, but I think I suffered something similiar when I
    tried to create a relationship between transient and committed object
    (e.g. Cliente object is commited and Contacto you add is transient and
    not registered in context).
