  • sortOrder - the order of sorting
  • firstRow - the first data row shown in the data table (corresponds to a page)
  • filter - the active list filter
  • referrerListOptions - the list options sortField, sortOrder, firstRow and filter encoded in a single parameter such they can be restored when navigating back to the list after editing a single entity
