Is it possible to create a table that has no 'id'? For example, this is my domain:

class SnbrActVector {

    int nid
    String term
    double weight

    static mapping = {
        version false
        id generator: 'identity'
    }

    static constraints = {
    }
}

When I run this SQL statement, it fails:

insert into snbr_act_vector values (5, 'term', 0.5)

I checked the table and 'id' is already set to autoincrement. I'm thinking that another option is to remove the 'id' itself. Or is there another workaround for this? Please assume that it is not an option to change the givent SQL statement.
