Add New Row in Table on click of a button

Question

Hi All,
I am using JDeveloper 11.1.5
I have a af:table with a detailFacet. In this detailFacet there is an af:commandButton. On click of this commandButton I want a new row to be added to the table programmatically.
In my Backing Bean I have following code for my button:
public String cb1_action() {
// Add event code here...
//RowKeySetImpl rowKeySet = new RowKeySetImpl();
CollectionModel tableModel = (CollectionModel)t1.getValue();
JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding)tableModel.getWrappedData();
DCIteratorBinding tableIteratorBinding = adfTableBinding.getDCIteratorBinding();
// DCDataRow rw = (DCDataRow)tableIteratorBinding.getRowSetIterator().createRow();
// tableIteratorBinding.getRowSetIterator().insertRow(rw);
Row lastRow = tableIteratorBinding.getNavigatableRowIterator().last();
Row newRow = tableIteratorBinding.getNavigatableRowIterator().createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
int lastRowIndex = tableIteratorBinding.getNavigatableRowIterator().getRangeIndexOf(lastRow);
tableIteratorBinding.getNavigatableRowIterator().insertRowAtRangeIndex(lastRowIndex+1, newRow);
tableIteratorBinding.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
AdfFacesContext.getCurrentInstance().addPartialTarget(t1);
return null;
On running this ,I get an Exception some thing like UnsupportedOperationException.
Please help me to find where I am wrong.
