James, Does your PagingQueryResult returned by your DAO by any chance wrap a Hibernate Criteria? Later the Criteria methods setMaxResults(), setFirstResult(), addOrder() and list() are invoked from the HibernateTableModel on request?
Or where do you invoke the criteria (or similar) methods? Marcus Matèrn On 7/24/06, James Carman <[EMAIL PROTECTED]> wrote:
Chris, Well, some of the code uses other classes that are part of the project I'm on. I need to refactor it out so that it can stand alone. I'll try to do that soon. Sorry for the delay.
