Controller Class Extension Problem

Question

Hi,
I am trying to extending controller class below is the code. When I click "FndGoButtonSubmit" at my page then it does not calling "setSequenceValue(pageContext, webBean)" method and no action take place at processFomeRequest method, although my code at processRequest works fine
super.processRequest(pageContext, webBean);
throw new OAException("Wrong Button Selected", OAException.WARNING);
package oracle.apps.eam.stores.materialissue.webui;
import oracle.apps.fnd.framework.OAException;
import oracle.apps.fnd.framework.webui.OAPageContext;
import oracle.apps.fnd.framework.webui.beans.OAWebBean;
import oracle.apps.eam.stores.materialissue.webui.EAMIssueMaterialMainCO;
import oracle.apps.eam.stores.materialissue.server.EAMMaterialResultTableVORowImpl;
import oracle.apps.fnd.framework.OAApplicationModule;
import oracle.apps.fnd.framework.OAViewObject;
import oracle.apps.fnd.framework.server.OADBTransaction;
import oracle.apps.icx.testapp.emptest.server.EmpTestVORowImpl;
import oracle.cabo.ui.beans.message.MessageTextInputBean;
import oracle.jbo.RowSetIterator;
import oracle.jbo.domain.Number;
public class TestCO extends EAMIssueMaterialMainCO {
public TestCO() {
public void processRequest(OAPageContext pageContext, OAWebBean webBean) {
super.processRequest(pageContext, webBean);
throw new OAException("Wrong Button Selected", OAException.WARNING);
public void processFomeRequest(OAPageContext pageContext,
OAWebBean webBean) {
super.processFormRequest(pageContext, webBean);
if (pageContext.getParameter("EamSubmitButton")!=null) {
setSequenceValue(pageContext, webBean);
else if (pageContext.getParameter("FndGoButtonSubmit")!=null) {
checkButton(pageContext, webBean);
else
throw new OAException("Else if Selected", OAException.WARNING);
public void setSequenceValue(OAPageContext pageContext,
OAWebBean webBean) {
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OADBTransaction transaction = am.getOADBTransaction();
OAViewObject vo =
(OAViewObject)am.findViewObject("EAMIssueMaterialResultTableVO");
System.out.println("Number of Rows are:" + vo.getRowCount());
Number sequencVal = transaction.getSequenceValue("TEST_SEQ_MAT");
EAMMaterialResultTableVORowImpl row = null;
RowSetIterator iterator = vo.createRowSet("iterator");
iterator.setRangeStart(0);
iterator.setRangeSize(vo.getRowCount());
System.out.println("OK!");
for (int i = 0; i < vo.getRowCount(); i++) {
row = (EAMMaterialResultTableVORowImpl)iterator.getRowAtRangeIndex(i);
row.setReference(sequencVal.toString());
public void checkButton(OAPageContext pageContext,
OAWebBean webBean) {
throw new OAException("Go Button Clicked", OAException.WARNING);

Haroon.

Hi Haroon,
You are calling at the start of the PFR super.processFormRequest(pageContext, webBean);//This will alway call your Parent Controller & hence your extended code will not get executed.
Put it at the end of the PFR.
public void processFomeRequest(OAPageContext pageContext,
OAWebBean webBean) {
super.processFormRequest(pageContext, webBean);
if (pageContext.getParameter("EamSubmitButton")!=null) {
setSequenceValue(pageContext, webBean);
else if (pageContext.getParameter("FndGoButtonSubmit")!=null) {
checkButton(pageContext, webBean);
else
throw new OAException("Else if Selected", OAException.WARNING);
public void setSequenceValue(OAPageContext pageContext,
OAWebBean webBean) {
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OADBTransaction transaction = am.getOADBTransaction();
OAViewObject vo =
(OAViewObject)am.findViewObject("EAMIssueMaterialResultTableVO");
System.out.println("Number of Rows are:" + vo.getRowCount());
Number sequencVal = transaction.getSequenceValue("TEST_SEQ_MAT");
EAMMaterialResultTableVORowImpl row = null;
RowSetIterator iterator = vo.createRowSet("iterator");
iterator.setRangeStart(0);
iterator.setRangeSize(vo.getRowCount());
System.out.println("OK!");
for (int i = 0; i < vo.getRowCount(); i++) {
row = (EAMMaterialResultTableVORowImpl)iterator.getRowAtRangeIndex(i);
row.setReference(sequencVal.toString());
