Serial number of PK column for table

Hi Experts,

I hung out and view object to the data control on the page jspx,.


First VO1 as ADF, as master and primary key (PkMaster)

Second VO2 as ADF Table, details and primary key(PkMaster,PkDetail)


I want to add a column autoincrement PkDetail do serial for every PkMaster for the table,

This autoincrements to the value with the number of rows in table

When to insert a new line.


Thanks in advance.

You can call this method after calling createInsert to detail to generate new sno and place it in the column

    /**Method to generate Serial Number for Table     * ***/

    public void generateSerial(String voName, String columnNm) {


        ViewObjectImpl vo = (ViewObjectImpl) this.findViewObject(voName);

       Row curRow = vo.getCurrentRow();

        Integer Srno = 0;

       Integer max = 0;

       vo.setRangeSize(-1);
        Row row[] = vo.getAllRowsInRange();

        for (Row r : row) {

            try {

                Srno = Integer.parseInt(r.getAttribute(columnNm).toString());

           } catch (NullPointerException e) {

                Srno = 0;
            }

       if (Srno > max) {

              max = Srno;

          }

       }
        max = max + 1;

       // System.out.println("Serial No is-" + max);

      curRow.setAttribute(columnNm, max);    }

just pass vo name and name of the pk column detail
