Sort an array

if(
  rule!GBL_isNull(
    ri!arrayValues
  ),
  {},
  reject(fn!isnull(_),a!flatten(
    todatasubset(
      a!forEach(
        items: ri!arrayValues,
        expression: {
          value: fv!item
        }
      ),
      a!pagingInfo(
        1,
        - 1,
        a!sortInfo(
          field: "value",
          ascending: or(
            ri!ascending
          )
        )
      )
    ).data.value
  ))
)
