Inkove method after close window with unload

Question

Hi guys,
I'm trying create a way the invoke a method in a BackingBean after close the window of browser for this I'm using the event unload of 'af:document'.
I used the Frank's sample ( http://blogs.oracle.com/jdevotnharvest/entry/responding_to_the_page_unload_in_a_managed_bean ) but it doesn't work.
Can anybody help me?
I'm using JDeveloper 11.1.2.0.0
This a part of my code :
Page
<f:view afterPhase="#{backingBeanScope.backing_mainPage.afterPhase}"
          beforePhase="#{backingBeanScope.backing_mainPage.beforePhase}">
    <af:document id="d1"
            binding="#{backingBeanScope.backing_mainPage.d1}"
            title="CTBC - Algar Telecom"
            smallIconSource="imgs/favicon.png imgs/favicon.ico"
            onunload="performUnloadEvent"
            clientComponent="true">
    <af:resource type="javascript">
            window.addEventListener('beforeunload', function (){performUnloadEvent()},false);
            function performUnloadEvent(){
              var eventSource = AdfPage.PAGE.findComponentByAbsoluteId('d1');
              var x = AdfCustomEvent.queue(eventSource,
                                           "handleOnUnload", {}, true);
              var y = 0;
    </af:resource>
    <af:serverListener type="handleOnUnload" method="#{sessaoLogoff.onUnloadHandler}"/>
      <af:form id="f1" binding="#{backingBeanScope.backing_mainPage.f1}">
.ManageBean
public class ControlaLogoff {
    public void onUnloadHandler(ClientEvent clientEvent) {
        System.out.println("good bye");
}Regards,

I just tested the code Frank provided (as is) and it worked for me. the only thing to mention is when I closed browser completely the bean isn't called. If I close the tab running the page all works as expected.
I strong feeling is that you simply can't catch the event if someone closes the browser (or use task kill). So if that is what you need you are out of luck.
Again, the other case works for me. So if it's not working for you I guess there is some kind of coding error in your app.
