When model updated,why SortableDataProvider.size() sometimes does not perform?

[J2EEKevinLIu Liu <j2...@yahoo.com>]

public class SortableUserDataProvider extends SortableDataProvider {
    private static final long serialVersionUID = 295668074163742165L;
    public SortableUserDataProvider() {
   setSort("id", true);
  }
    public Iterator<UserVO> iterator(int first, int count) {
   DetachedCriteria criteria = queryForm.buildCriteria();
   if(this.getSort().isAscending()){
    criteria.addOrder(Order.asc(this.getSort().getProperty()));
   }else{
    criteria.addOrder(Order.desc(this.getSort().getProperty()));
   }
   List<User> users = queryService.list(criteria, first, count);
   return convertToVO(users);
  }
    private Iterator<UserVO> convertToVO(List<User> users) {
   ArrayList<UserVO> userVOs = new ArrayList<UserVO>();
   for (User user : users) {
    if (user != null) {
     userVOs.add(new UserVO(user, publicDataService));
    }
   }
   return userVOs.iterator();
  }
    public int size() {
   return queryService.count(queryForm.buildCriteria());//the queryForm has 4 textFields,create query from user's input. 
  }
    public IModel model(Object object) {
   return new Model((UserVO) object);
  }
 }

abstractpageableview caches the size() of the list - which can lead to this.
try with latest trunk, i believe i just fixed it.
