    You don't need this line - Cayenne will generate PK for you. Unless you
    have a really good reason to do that, I will go further and recommend
    to remove ID attribute from Java class and let Cayenne handle it all
    the way. If you need to read generated ID, use DataObjectUtils -

    DataObjectUtils.html
