Dynamic Query Refcur comes back empty?

Question

Has anyone seen this problem. I have been using ref cursors to pass back data on procedure calls. When I use static sql and "OPEN <yourrefcursor> FOR", everything works fine. When I use NDS/Dynamic SQL the same query fails to return anything. Anybody know why? I know that the dynamic SQL works because I have tested it with a debugger. It just doesn't return results for ODP.NET calls

TYPE empty_refcursor IS REF CURSOR RETURN dual%ROWTYPE;
FUNCTION getEmptyCursor RETURN empty_refcursor
IS empty_rc empty_refcursor;
BEGIN
OPEN empty_rc
FOR SELECT sysdate
FROM dual;
RETURN empty_rc;
END getEmptyCursor;
PROCEDURE processCursor
(p_grid_resultset OUT NOCOPY empty_refcursor )
IS
BEGIN
p_grid_resultset:=getEmptyCursor ;
END processCursor;
