Need more info. Is your next page loading, or are you getting a null
pointer exception on the first page. If your next page is loading, are you
getting a null pointer exception, or is it that the field that is supposed
to display the value is empty. And have you turned on terse (I think)
debugging in the rdbms service to see what actual SQL is being generated to
retrieve the row that contains the value.
