This is my Controller code for the Newly created page....
package oracle.apps.fnd.employee.webui;
import oracle.apps.fnd.common.VersionInfo;
import oracle.apps.fnd.framework.webui.OAControllerImpl;
import oracle.apps.fnd.framework.webui.OAPageContext;
import oracle.apps.fnd.framework.webui.beans.OAWebBean;
import oracle.apps.fnd.framework.OAApplicationModule;
import oracle.apps.fnd.framework.webui.OADialogPage;
import oracle.apps.fnd.framework.webui.TransactionUnitHelper;
* Controller for ...
public class EmployeeCreateCO extends OAControllerImpl
public static final String RCS_ID="$Header$";
public static final boolean RCS_ID_RECORDED =
VersionInfo.recordClassVersion(RCS_ID, "%packagename%");
* Layout and page setup logic for a region.
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
// If isBackNavigationFired = false, we're here after a valid navigation
// (the user selected the Create Empoyee button) and we should proceed
// normally and initialize a new employee.
if (!pageContext.isBackNavigationFired(false))
// We indicate that we are starting the create transaction (this
// is used to ensure correct Back button behavior).
TransactionUnitHelper.startTransactionUnit(pageContext, "empCreateTxn");
// This test ensures that we don't try to create a new employee if
// we had a JVM failover, or if a recyled application module
// is activated after passivation. If this things happen, BC4J will
// be able to find the row that you created so the user can resume
// work.
if (!pageContext.isFormSubmission())
OAApplicationModule am = pageContext.getApplicationModule(webBean);
am.invokeMethod("createEmployee", null);
// Iniitalize the ApplicationPropertiesVO for PPR.
am.invokeMethod("init");
else
if (!TransactionUnitHelper.isTransactionUnitInProgress(pageContext,"empCreateTxn", true))
// We got here through some use of the browser "Back" button, so we
// want to display a stale data error and disallow access to the page.
// If this were a real application, we would probably display a more
// context-specific message telling the user she can't use the browser
// "Back" button and the "Create" page. Instead, we wanted to illustrate
// how to display the Applications standard NAVIGATION ERROR message.
OADialogPage dialogPage = new OADialogPage(NAVIGATION_ERROR);
pageContext.redirectToDialogPage(dialogPage);
* Procedure to handle form submissions for form elements in
* a region.
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
