校验基于EO的VO中的字段是否发生变化

I have a table region and there are multiple records fetching from a Entity based VO. Now I have updated one row or any of row, I require to display once changed records on next page. How can I display? I want to capture row status type thing while pressing the save button.

if(row.getEntity(0).getPostState()==2){

　　//your logic

}

xxPerPhonesVORowImpl updatedRow = (xxPerPhonesVORowImpl)EmpContactsVO.getCurrentRow();

System.out.println("Row Status : " + updatedRow.getxxPerPhonesEO().getEntityState());

if(updatedRow.getxxPerPhonesEO().getEntityState() == EntityImpl.STATUS_NEW  ) {

System.out.println("Row Status : Row # " + i + " : Modified value : "  + updatedRow.getEntity(0).getEntityState());

}

最佳答案：

ssue resolved by creating a new field (IS_SUBMITTED) in database table to Flag the record status with the default value as N (update all the existing records if there are any in the table);

Step 1 : Go to properties on your EO and navigate to Java and check Data Manipulation

Step 2 : Go to your EOImpl class and search for doDML method

Step 3 : Under doDML method add below code to set EO Attribute value;

if (getIsSubmitted().equals("N")) {

setIsSubmitted("M"); //where as M stands for Modified

}

Step 4 : Under your Controller Class @ PFR, write code for loop and set the attribute status like below;

OAApplicationModule am = pageContext.getApplicationModule(webBean);

if (pageContext.getParameter("SubmitButton") != null ) {

am.invokeMethod("apply");   //saving the records so the EOImpl will set the is_submitted to 'M' wherever the record modified state found

OAViewObject EmpPhoneVO = (OAViewObject)am.findViewObject("xxPerPhonesVO1");

int empPhoneRowCnt = EmpPhoneVO.getRowCount();

EmpPhoneVO.first();

for (int i=1; i<=empPhoneRowCnt; i++){

OARow empPhoneRow = (OARow)EmpPhoneVO.getCurrentRow();

String lPhoneValidated = "Y";

// your validation if any

if (lPhoneValidated.equals("Y")) {

System.out.println("IsSubimtted After Get : " + empPhoneRow.getAttribute("IsSubmitted"));

if (empPhoneRow.getAttribute("IsSubmitted").equals("M")){

empPhoneRow.setAttribute("IsSubmitted","S");

}

System.out.println("IsSubimtted After Set : " + empPhoneRow.getAttribute("IsSubmitted"));

OAException submitMessage = new OAException("Employee Contact Details : Row # " + i +  " : Submitted for Approval to Employee Relation Officer.",

OAException.CONFIRMATION  );

pageContext.putDialogMessage(submitMessage);

}

EmpPhoneVO.next();

}

}
