Default value of radio button on first row in table

Question

Hi,
I have created a custom page which includes a table ("SuppliersTable"), the table has a singleSelection table component (radio button) linked to a transient attribute ("SelectFlag") in a VO ("ApSuppliersVO"). The table is populated from a Query region.
I would like to 'select' the radio button on the first row of the table by default when a query is executed (when a user clicks "Go"), I have tried the following but its not setting the value:
In CO:
        if (pageContext.getParameter(go) != null) {
            System.out.println("The GO button was pressed");
            am.invokeMethod("handleFirstRows");
        }In AMImpl:
    public void handleFirstRows() {
        System.out.println("1");
        OAViewObject suppliersVO =
            (OAViewObject)findViewObject("ApSuppliersVO");
        if (suppliersVO != null) {
            System.out.println("2");
            int rowcnt = suppliersVO.getRowCount();
            System.out.println("RowCount:" + rowcnt);
            if (suppliersVO.getFetchedRowCount() != 0) {
                System.out.println("3");
                //OARow supplierRow = (OARow)suppliersVO.first();
                Row supplierRow1 = suppliersVO.first();
                supplierRow1.setAttribute("SelectFlag", "Y");
    }Based on the debug messages I can see that it is calling the procedure, but either not setting the value, or not setting it in a way that renders it on the page and forces the event that goes with it.
Am I missing something/doing it completely wrong? How can I best achieve this?

Hey hi Carl,
Its pretty much correct , well , can you try the below code .
OAViewObject localOAViewObject1 = (OAViewObject)am.findViewObject("ProjectDatesVO");
if(localOAViewObject1!=null) {
Row DateVoROw = localOAViewObject1.first();
RowSetIterator iterator = localOAViewObject1.createRowSetIterator("iterator");
iterator.setRangeStart(0);
iterator.setRangeSize(localOAViewObject1.getRowCount());
for(int i=0; i<iterator.getRowCount(); i++)
DateVoROw=iterator.getRowAtRangeIndex(1); // represents first row
if(DateVoROw!=null)
// set the value here .
Kindly Let me know the update .
