Need to add a new row at the end of the table

Question

Experts,
working jdev 11.1.1.3.0
i am adding row programetically, my requirement need to add the row at after last row.
i tried different ways.
Row newLastRow = getPWBBidLaneVO().last();
int lastRowIndex = getPWBBidLaneVO().getRangeIndexOf(newLastRow);
getPWBBidLaneVO().insertRowAtRangeIndex(lastRowIndex - 1,
laneRow);
this is giving --- java.lang.ArrayIndexOutOfBoundsException: 0
and
http://kohlivikram.blogspot.com/2008/10/add-new-row-in-adf-table-on-button.html --- its giving index out of bound because vo.getRangeSize() is 25. We set this value at vo for performance improment suggestions.
is there a way to add a new row at the end of the table?

Answer 1

Add this to the view row impl class
       public void insertRow(Row row) {
           //go to the end of Rowset if it has rows
           Row lastRow = this.last();
           if (lastRow !=null){
                //insert new row at the end and make it current
               int indx = this.getRangeIndexOf(lastRow)+1;
               this.insertRowAtRangeIndex(indx,row);
               this.setCurrentRow(row);
           }else { // empty Rowset
           super.insertRow(row);
           }
