     value is an array of arrays of objects on the form:

          ({
              ({Same1:1, Same1:2, Same1:3, .... Same1:N }),
              ({Same2:1, Same2:2, Same2:3, .... Same2:N }),
              ({Same3:1, Same3:2, Same3:3, .... Same3:N }),
                            ....
              ({SameM:1, SameM:2, SameM:3, .... SameM:N }),
