How to skip validation using serverListener

Question

Hi,
I am using Jdev 11.1.2.3.0
My requirement was to called some action using the keyboard key.
I tried with Access key first but its behaving differently in different browser.
Crome: allowing action on access key press.
IE : setting the focus on commandLink.
Note : I have defined accessKey for RichCommandLink.
Then i used the different approach which is as follows:
1- Register the keyBoard handler to document. on beforePhase Event.
2- Added the js file as follows :
Javascript file:
var keyRegistry = new Array();
keyRegistry[0] = "alt 1";
keyRegistry[1] = "alt 2";
keyRegistry[2] = "alt 3";
keyRegistry[3] = "alt 4";
keyRegistry[4] = "alt 5";
keyRegistry[5] = "alt 6";
keyRegistry[6] = "alt 7";
keyRegistry[7] = "alt 8";
keyRegistry[8] = "alt 9";
keyRegistry[9] = "alt 0";
function registerKeyBoardHandler(serverListener, afdocument) {
  _serverListener = serverListener;
  var document = AdfPage.PAGE.findComponentByAbsoluteId(afdocument);
  _document = document;
  for (var i = keyRegistry.length - 1; i >= 0; i--) {
    var keyStroke = AdfKeyStroke.getKeyStrokeFromMarshalledString(keyRegistry);
AdfRichUIPeer.registerKeyStroke(document, keyStroke, callBack);
function callBack(keyCode) {
var activeComponentClientId = AdfPage.PAGE.getActiveComponentId();
// Send the marshalled key code to the server listener for the developer
// To handle the function key in a managed bean method
var marshalledKeyCode = keyCode.toMarshalledString();
AdfCustomEvent.queue(_document,
_serverListener, {keycode:marshalledKeyCode,
    activeComponentClientId:activeComponentClientId}, true);
// indicate to the client that the key was handled and that there
// is no need to pass the event to the browser to handle it
return true;
*jspx page:*
        <f:view beforePhase="#{KeyboardHandler.registerKeyboardMapping}">
<f:loadBundle basename="properties/Labels" var="labels"/>
<af:document id="adfDocument">
<af:resource type="javascript" source="/js/keyboard.js"/>
<af:serverListener type="keyboardToServerNotify" method="#{KeyboardHandler.handleKeyboardEvent}" />
</af:document>
</f:view>
*Java Code :*
        public class KeyboardHandler {
public KeyboardHandler() {
super();
public void registerKeyboardMapping(PhaseEvent phaseEvent) {
if (phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExtendedRenderKitService extRenderKitService =
Service.getRenderKitService(facesContext,
ExtendedRenderKitService.class);
List childComponents = facesContext.getViewRoot().getChildren();
//First child component in an ADF Faces page - and the only child - is af:document
//Thus no need to parse the child components and check for their component family
//type
String id =
((UIComponent)childComponents.get(0)).getClientId(facesContext);
StringBuffer script = new StringBuffer();
script.append("window.registerKeyBoardHandler('keyboardToServerNotify','" +
id + "')");
extRenderKitService.addScript(facesContext, script.toString());
public void handleKeyboardEvent(ClientEvent clientEvent) {
String keyCode = (String)clientEvent.getParameters().get("keycode");
System.out.println("KeyCode ::"+keyCode);
//Here on basis of numeric key 0-9 i will decide different action
This is working fine and launching the first action successfully.
*Now problem is that when i invoked second action its asking me enter data for required fields.*
If i was invoking serverlistener from button than I can control immediate property of command button. but here serverListener is getting called form document. How can I avoid validation here.
Can anybody please me?
Thanks a lot in advance.
