关于adf中的DataControl

Question

我正在使用Oracle EBS开发一个ADF Web应用程序作为调用该过程的后端（Jdeveloper 12 c）。

我调用了一个调用EBS过程的方法（返回类型为list），结果存储在arraylist中。该列表用于创建数据控件。 我的问题是我为数据控件设置了值但是当我添加dc来查看它时什么都没有显示。但是在调试时它会显示所有值都在数组列表中设置。

Bean类在ApplicationModule中调用EBS过程

    BindingContainer bindings = getBindings();        
    OperationBinding operationBinding = (OperationBinding) bindings.getOperationBinding("getIexpenseLogin");
    List<EmployeePojo> result = (List<EmployeePojo>) operationBinding.execute();
    System.out.println("Result= " + result); 
    employeeDC.getEmployeeLogin(result);  // Here the list is passed to the Employee DC class to create data controll.

包含自定义过程的ApplicationModule

    public List getIexpenseLogin(String username,String password){

   CallableStatement cs=null;
   List<EmployeePojo> empList=new ArrayList<>(); 

   try{

   cs=getDBTransaction().createCallableStatement("begin xx_oie_mob_login.oie_mob_login(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?); end;",0);
   cs.setString(1,username);
   cs.setString(2, password);    
   cs.registerOutParameter(3, Types.NUMERIC);
   cs.registerOutParameter(4, Types.VARCHAR);
   cs.registerOutParameter(5, Types.VARCHAR);
   cs.registerOutParameter(6, Types.NUMERIC);
   cs.registerOutParameter(7, Types.VARCHAR);
   cs.registerOutParameter(8, Types.NUMERIC);
   cs.registerOutParameter(9, Types.VARCHAR);
   cs.registerOutParameter(10, Types.NUMERIC);
   cs.registerOutParameter(11, Types.VARCHAR);
   cs.registerOutParameter(12, Types.NUMERIC);
   cs.registerOutParameter(13, Types.BLOB);
   cs.registerOutParameter(14, Types.VARCHAR);
   cs.registerOutParameter(15, Types.VARCHAR);
   cs.executeUpdate();
   if(cs!=null)
   {

       EmployeePojo ePojo=new EmployeePojo();
       ePojo.setEmployeeId(cs.getString(3));
       ePojo.setEmployeeName(cs.getString(4));
       ePojo.setEmployeeNumber(cs.getString(5));
       ePojo.setManagerId(cs.getString(6));
       ePojo.setManagerName(cs.getString(7));
       ePojo.setJobId(cs.getString(8));
       ePojo.setJobName(cs.getString(9));
       ePojo.setOrgId(cs.getString(10));
       ePojo.setOrgName(cs.getString(11));
       ePojo.setImgId(cs.getString(12));
       ePojo.setImage(cs.getBlob(13));
       empList.add(ePojo);

   }


   return empList;

   }catch(SQLException e){

   throw new JboException(e);

   }

   }

用于创建Data controll的EmployeeDC类

public class EmployeeDC {
public EmployeeDC() {
    super();
}
BindingContainer bindings = null;
private List<EmployeePojo> employee_data_controll=null;
private PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport(this);

public void setEmployee_data_controll(List<EmployeePojo> employee_data_controll) {
    List<EmployeePojo> oldEmployee_data_controll = this.employee_data_controll;
    this.employee_data_controll = employee_data_controll;
    propertyChangeSupport.firePropertyChange("employee_data_controll", oldEmployee_data_controll,
                                             employee_data_controll);
}

public List<EmployeePojo> getEmployee_data_controll() {
    return employee_data_controll;
}

public void setPropertyChangeSupport(PropertyChangeSupport propertyChangeSupport) {
    PropertyChangeSupport oldPropertyChangeSupport = this.propertyChangeSupport;
    this.propertyChangeSupport = propertyChangeSupport;
    propertyChangeSupport.firePropertyChange("propertyChangeSupport", oldPropertyChangeSupport,
                                             propertyChangeSupport);
}
public PropertyChangeSupport getPropertyChangeSupport() {
    return propertyChangeSupport;
}

public void getEmployeeLogin(List<EmployeePojo> result) {
    setEmployee_data_controll(result);
    getEmployee_data_controll();
    System.out.println("DataControl=>"+getEmployee_data_controll().get(0));
}

public void addPropertyChangeListener(PropertyChangeListener l) {
    propertyChangeSupport.addPropertyChangeListener(l);
}

public void removePropertyChangeListener(PropertyChangeListener l) {
    propertyChangeSupport.removePropertyChangeListener(l);
}

}
