I have a problem about session.scroll();

when use , the return Object is the first column that type is 'String' ,not 'User' class , it's so strange.

but in hibernate 2.1 ,the return type is 'User' class .

Thanks

Code between sessionFactory.openSession() and session.close():
String sql="select new User(userID,name) from User";
List result=new ArrayList();
ScrollableResults srs= session.createQuery(sql).scroll();
while (srs.next()) {
System.out.println(srs.get(0));
}
