Unable to Clear VO Cache : Tutorial Create-Part2.

Question

I am tring to create a new record using the steps in create - Part2 of the toolbox tutorial in Jdev.I am facing issue at step: Step 3.5 .
When I run EmpSearchPG-->(Button)Create Employee -->EmployeePG
on this page it picks teh first row from the table and displays the data in the respective fields.
And error I get is :
Error
EmployeeId - Employee number cannot be updated.
Although I have set the attribute property of EmployeeID to updateable when new ,
and am doing vo.clearcache().
I have gone through many threads but coudnt find the solution. I am hoping someone will give me a clue.
My code in EmployeeCreateCO:
    if (!pageContext.isFormSubmission())
       OAApplicationModule am = pageContext.getApplicationModule(webBean);
       am.invokeMethod("createEmployee", null); 
     }EmployeeAM:
  public void createEmployee()
    OAViewObject vo = (OAViewObject)getEmployeeFullVO1();
    if (!vo.isPreparedForExecution())
     vo.clearCache();
    vo.executeQuery();  
     Row row = vo.createRow();  
    vo.insertRow(row);   
    row.setNewRowState(Row.STATUS_INITIALIZED);
  } // end createEmployee()EmployeeEO :
  public void create(AttributeList attributeList)
    super.create(attributeList);
   System.out.println( "EmployeeEOImpl- create() method " );
    OADBTransaction transaction = getOADBTransaction();
    Number employeeId = transaction.getSequenceValue("FWK_TBX_EMPLOYEES_S");
   System.out.println("employeeId = " + employeeId); //generates unique id for each run
    setEmployeeId(employeeId);  //cant set it though
public void setEmployeeId(Number value)
    setAttributeInternal(EMPLOYEEID, value);
  System.out.println("EmployeeEOImpl");
  System.out.println("1 value = " + value);       //--------------this gets printed
  System.out.println("2 getEmployeeId() = " + getEmployeeId());      //--------------this gets printed
    if (getEmployeeId() != null)
    System.out.println("3 value = " + value);  //////--------------this gets printed
    System.out.println("4 getEmployeeId() = " + getEmployeeId());    //--------------this gets printed
      throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
                                   getEntityDef().getFullName(), // EO name
                                   getPrimaryKey(), // EO PK
                                   "EmployeeId", // Attribute Name
                                    value, // Attribute value
                                   "AK", // Message product short name
                                   "FWK_TBX_T_EMP_ID_NO_UPDATE"); // Message name
    if (value != null)
      System.out.println("5 value = " + value);  ////--------------doesnt get printed
      System.out.println("6 getEmployeeId() = " + getEmployeeId());           //doesnt get printed
      OADBTransaction transaction = getOADBTransaction();
      Object[] employeeKey = {value};
      EntityDefImpl empDefinition = EmployeeEOImpl.getDefinitionObject();
      EmployeeEOImpl employee =
        (EmployeeEOImpl)empDefinition.findByPrimaryKey(transaction, new Key(employeeKey));
      if (employee != null)
        throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
              getEntityDef().getFullName(), // EO name
              getPrimaryKey(), // EO PK
              "EmployeeId", // Attribute Name
              value, // Attribute value
              "AK", // Message product short name
              "FWK_TBX_T_EMP_ID_UNIQUE"); // Message name
    setAttributeInternal(EMPLOYEEID, value);
  } // end setEmployeeId()

Answer 1

In your setEmployeeId method, you are having setAttributeInternal(EMPLOYEEID, value); as the first line. This is leading to the issue. Move it to the end of the method and your problem will be solved.
As you are calling this in the first line, all the validations which should be fired before setting the Employee Id are getting fired after setting the Employee Id.
