    Hmm... primary key is -956712157. Do you have primary key generation
    table setup per User Guide?

    Anyway, this may or may not be related to the error below.. Stack trace
    shows that the error occurs when trying to resolve PLZ->Address to-many
    relationship. Could you send me your XML Data Map file directly. I want
    to see how this particular relationship and both entities are mapped.
