How to append new row in rowset with parameter?

Question

Hi,
In the data input page in prerender method I have this code to filter rowset with non existing id in the table to show empty table on the page:
try {           
            getSessionBean1().getKoordinatesRowSet().setObject(1, non_existing_id);
        } catch (Exception e) {
            error("klaida koord " + e);
        }After this I have empty table and I want with a button on the page append one or more rows, fill them and save to my db. I try with this code:
public String addBtn_action() {       
        try {           
            RowKey rk = koordinatesDataProvider.appendRow();           
            koordinatesDataProvider.setCursorRow(rk);                           
        } catch (Exception ex) {
            log("Negaliu prideti eilutes ", ex);
            error(ex.getMessage());
        return null;
    }But new row does not appear. When I remove parameter in RowSet and remove code from prerender method all works fine, but I see all data from the table that was entered before. Like I said - I want to have an empty table and be able to append one or more new rows, fills them and save to my db. How can I resolve this?

Rui's answer will create copies of the entire table.  There may be times where thsi is what you want, but you asked about creating new rows.  If your new row is a copy of one of your existing rows, then you could use
_RowName.addInstance(1);
(the underscore at the beginning invokes the instance manager).  Is this what you're looking for?
