删除或更新项目后数据表未刷新

我试图在primefaces上实现排序功能dataTable.Sorting正在运行。但是当我删除时,更新dataTable项,dataTable没有任何影响(没有任何变化)。那就是dataTable没有被清除或刷新。但是在数据库删除中,更新没有发生任何问题。当我退出并重新登录时,新列表(dataTable)没问题。

employeeView.jsf:

<p:dataTable id="employees" value="#{employeeList.employees}"
     var="employee" emptyMessage="No Employees found" rows="10"
     paginator="true"
     paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink}  {PageLinks}      {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
     rowsPerPageTemplate="5,10,15" rowIndexVar="rowIndex">

        <p:column sortBy="#{employee.firstName}">
           <f:facet name="header">
           <h:outputText value="First Name" />
           </f:facet>
           <h:outputText value="#{employee.firstName}">
           </h:outputText>
        </p:column>
            <p:column sortBy="#{employee.lastName}">
           <f:facet name="header">
           <h:outputText value="Last Name" />
           </f:facet>
           <h:outputText value="#{employee.lastName}" />
        </p:column>
    </p:dataTable>

EmployeeList.java:

@Component("employeeList")
@SessionScoped
@Repository
public class EmployeeList implements Serializable {
    private static final long serialVersionUID = -2417394435764260084L;


    public static HibernateTemplate hibernateTemplate;
   private List<Employee> employees = new ArrayList<Employee>();

    @Autowired
    public void setSessionFactory(SessionFactory sessionFactory)
    {       
        this.hibernateTemplate = new HibernateTemplate(sessionFactory);     
    }



   public List<Employee> getEmployees() {
    if(employees.isEmpty()){
       employees.addAll(empList());
    }
    return employees;
}


    @SuppressWarnings("unchecked")
    public List<Employee> empList() {       
        try
        {           
            List <Employee> result =  hibernateTemplate.find("from Employee"); 
            return result;
        }
        finally { 
            //close the session and user-supplied JDBC connection 
        }

    }

}

我曾尝试使用@RequestScope,@ ViewScope等但没有效果。我哪里出错了?

使用JSF2和Google Cloud SQL的Primefaces-3.0.M3
