    Denna,

    You'll have to check "to dep pk" checkbox on the Deal (master) side of the
    relationship -
    http://objectstyle.org/cayenne/modelerguide/modeling-db-layer/to-dep-pk.html

    This way Cayenne will know which table is master (so a PK is generated for
    it) and which one is dependenct (i.e. its pk is taken from master).
