    Since you are using flattened relationship (user.id + group.id), will need
    to manage one site (User will manage) of it through the other (Group will be
    managed).

    When the association table has attributes, that means you relationship needs
    an obj-entity to set/get those attributes (in your case: UserGroup)

    Using this design you can set default values to UserGroup. See this
    discussion [1].

    Hope this help,
