Insert New Row in ADF ViewObject Programatically

Here I am showing how to insert new row in ADF view object programmatically.

For this create a method in managed bean for your button on that you want to insert row.
and call this AMImpl method that makes use of ViewObjectImpl createRow method to add new row in RowSet

Created a method in AMImpl class and it'll be called in managed bean using binding layer

This method creates a row in ViewObject , and you can set(Insert) this row with some values using this simple snippet of code 

//Get ViewObject Instance
    ViewObjectImpl demoVo = this.getEmployeesDemo1();

// Creates a row in ViewObject
    Row r = demoVo.createRow();  
// You can set attribute values in this new row
    r.setAttribute("EmployeeId", 001); 

//Insert that row in ViewObject
//Commit the changes, If you need

This is how you can create row in ViewObject

  •     BigDecimal to Integer
  •     Integer to BigDecimal
  •     Double to Integer
  •     Integer to double

package practiceJava;

import java.math.BigDecimal;

public class TypeConversion {
    public static void main(String[] args) {
        /*Convert String to Integer*/
        String name = "1234";
        Integer nm = Integer.parseInt(name);
        System.out.println("Name in Integer-->" + nm);

    /*Convert Integer to String*/

    Integer a = 23;
    String num = a.toString();
    /*BigDecimal to Integer*/
    BigDecimal nom = new BigDecimal(450.9);
    Integer nomInt = nom.intValue();

    /*Integer to BigDecimal*/

    Integer cm = 45;
    BigDecimal cmBd = new BigDecimal(cm);
    /*Double to Integer*/

    double sys = 3;
    Integer sysInt = new Integer((int)sys);
   /*Integer to double*/
    Integer sd = 456;
    double sdDb = sd.doubleValue();
