public UserpaginationDTO getUsers(int start,int limit) throws DomainException, SystemException {
logger.info("Entering in :< [AdminDaoImpl][getUsers] >");
Session session = getSession() ;
List<UserpaginationDTO> usersListCount = new ArrayList<UserpaginationDTO>() ;
UserpaginationDTO userpagination=new UserpaginationDTO();
List<User> usersList = null ;
try{
if(limit== -1){
limit=999999999;
}
usersListCount=session.createCriteria(User.class).list();
usersList = session.createCriteria(User.class).setFirstResult(start).setMaxResults(limit).addOrder(Order.desc("id")).list() ;
userpagination.setUser(usersList);
userpagination.setTotalUsers(usersListCount.size());
}catch(Exception e){
logger.error("Exception Occured",e) ;
}finally{
releaseSession(session) ;
logger.info("Exit from :< [AdminDaoImpl][getUsers] >");
return userpagination;

When you remove the records from the store, you could load the store to get an update in the total count and get things back in line.
