How to set a default text to a Keyflexfield

Question

I need to set a text value to a Key flex field. This text value will be decided at runtime based on other field value. Can any one help me to default a text value to a Key flex field

Before deafulting a value in KFF on my custom page, I did a exercise given in the devguide tutorial. And The code as follows. Can you please help me by placing required code.
Controller:ItemDetailsCO
public void processRequest(OAPageContext pageContext, OAWebBean webBean) {
// Always call this first.
super.processRequest(pageContext, webBean);
// Get the itemNumber parameter from the URL
String itemNumber = pageContext.getParameter("itemNumber");
// Now we want to initialize the query for our single item
// with all of its details.
OAApplicationModule am = pageContext.getApplicationModule(webBean);
Serializable[] parameters = { itemNumber };
am.invokeMethod("initDetails", parameters);
OAKeyFlexBean flexBean =
(OAKeyFlexBean)webBean.findIndexedChildRecursive("KeyFF");
flexBean.setStructureCode("FWK Item Flexfield");
flexBean.setCCIDAttributeName("FwkitemId");
flexBean.setDynamicInsertion(true);
flexBean.mergeSegmentsWithParent(pageContext);
// Now check to see if our "Results" VO has been queried so we can set the
// region header text accordingly.
System.out.println("Flex bean text"+flexBean.getText());
Serializable[] params = { "ItemDetailsVO1" };
if ("Y".equals(am.invokeMethod("isVOQueried", params))) {
System.out.println("Flex bean text"+flexBean.getText());
flexBean.setRendered(true); // Render Key FF only after VO Queried }
AM : FlexfieldAMImpl.java
* Initializes the item details query.
public void initDetails(String itemNumber) {
ItemDetailsVOImpl vo = getItemDetailsVO1();
if (vo == null) {
MessageToken[] errTokens =
{ new MessageToken("OBJECT_NAME", "ItemDetailsVO1") };
throw new OAException("AK", "FWK_TBX_OBJECT_NOT_FOUND", errTokens);
// First, construct an oracle.jbo.Key object as required in the Key constructor
// Javadoc. Then, call findByKey indicating that we're looking for a single
// row. BC4J tries to find the entity object(s) for this row in its cache, and failing
// that, will query from the database using the given key.
String[] keys = { itemNumber };
Row[] rows = vo.findByKey(new Key(keys), 1);
// You must set the current row, or the Details page won't display any
// data. When you explicitly query data, you don't have to do this
// because the OA Framework automatically invokes vo.first() in the
// result set, thereby establishing a current row.
if (rows != null) {
// rows[0].setAttribute("ItemId","1");
vo.setCurrentRow(rows[0]);
} // end initDetails()
public String isVOQueried(String viewUsageName) {
OAViewObject vo = (OAViewObject)findViewObject(viewUsageName);
if (vo == null) {
MessageToken[] tokens =
{ new MessageToken("OBJECT_NAME", viewUsageName) };
throw new OAException("AK", "FWK_TBX_OBJECT_NOT_FOUND", tokens);
return (vo.isPreparedForExecution()) ? "Y" : "N";
} // end isVOQueried(}
Thanks in Advance
