Adding a new row programatically

Question

I have the following use case :
1) I have a jsf page having adf table which displays all the records from the employees table of hr schema.
2) pagination was implemented on this table and this table contains two buttons "Add New Row" and "Save".These buttons will be displayed in every page.
3) when the "Add New Row" is clicked,a new row has to be inserted as the last record of adf table in jsf page.
i.e suppose if the employees table contains 45 records,the adf table in my .jspx page displays 5 pages(each page contains 10 records).If i click "Add new row" button in page 2,the new record should be inserted as the 46th record in the 5 th page and the control should transfer to 5th page to enter the values for the new row.
4)After entering the values and save button is clicked,all the values of newly inserted rows should be inserted into the database.
How to acheive this functionality.
I did the following :
1)created the entity and view objects.
2)written a bussiness method in AMImpl to insert a new row when the 'Add new row" button is clicked.But this method is inserting the new row as the last record in the same page that I performed the operation.
Below is my code snippet :
public void addNewRow(){
Row newRow=getEmployeeObj().createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
EmployeeUVOImpl vo = (EmployeeUVOImpl)getEmployeeObj();
int res=vo.getFetchedRowCount()/vo.getRangeSize();
int remin=vo.getFetchedRowCount()%vo.getRangeSize();
if((vo.getFetchedRowCount()%vo.getRangeSize())>0){
vo.insertRowAtRangeIndex(vo.getRangeSize(),newRow);
else{
vo.insertRowAtRangeIndex(vo.getRangeSize()-1,newRow);
Thanks in Advance,

Hi,
the code below works in JDeveloper 11g. However, it works similar for 10.1.3 so you may want to have a look
    public String newRowAction() {
        CollectionModel tableModel = (CollectionModel) table1.getValue();
        JUCtrlHierBinding adfModel = (JUCtrlHierBinding) tableModel.getWrappedData();
        DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
        Row lastRow = dciter.getNavigatableRowIterator().last();
        Row newRow  =  dciter.getNavigatableRowIterator().createRow();
        newRow.setNewRowState(Row.STATUS_INITIALIZED);
        int lastRowIndex = dciter.getNavigatableRowIterator().getRangeIndexOf(lastRow);
        dciter.getNavigatableRowIterator().insertRowAtRangeIndex(lastRowIndex+1, newRow);
        dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
        //table should have its displayRow attribute set to "selected"
        AdfFacesContext.getCurrentInstance().addPartialTarget(table1);
        return null;
    }Frank
