I thought this would switch the order correctly but as you said I should be returning a SortOrderEnum.ASCENDING when sort=asc and SortOrderEnum.DESCENDING when sort=desc. Many thanks for your help, two heads are better than one! John. Hoying, Ken wrote: > Thank you, John!!! > > The tip on sortProperty was instrumental.
