FindComponent in pagetemplate ??

Question

Hi,
I have a pagetemplate in which I would like to put some javascript functionality.
Therefore I need the AdfPage.PAGE.findComponent function.
The problem is that in my other pages the reference to the page template has different ids (sometimes the
pagetemplate - which is a naming container - is called templateID, sometimes chickenID, or testID,...whatever).
I have read that it is possible to "search" within containers using several colons, but this does not (seem to) work in my case.
Here is some info on what I am trying to achieve :
I wish to have a dialog box asking the user if he wishes to save changes before he exits. Not too much asked I guess.

Hi,
I think in the upcoming R1 release there is an automated option for this (though not customizable. I am not aware of anything in the current build of JDeveloper 11g . What about using an af:clientListener in an unload event to call a serverListener to check the state of the transaction ?

Re: how to popup confirm dialog trying to navigate away with unsaved change
Now that looks like a good idea, but here's the hick-up.
When using a custom event AdfCustomEvent.queue(...) you NEED a valid source UIComponent or the framework will never deliver the event to the serverlistener.
Now it seems pretty clear to me that that user, and myself, did not intend to write this same code over and over in each and every page...
Lets put the code in our template...oh..hell..the (triple) colons in AdfPage.PAGE.findComponent(":::comp1") don't work in a template!
EDIT : Using ADF 11g

Thanks a lot, and sorry for the crude way of putting it..but I had been looking for an answer for some time now
and got kinda frustrated ;D
But thanks a lot!
No it did not work.
Well at least what I thought you meant did not work.
Here is what I have now :
template
        <af:commandButton text="commandButton 1" immediate="true" partialSubmit="true" action="#{Bb_Common_Template.testbis}"/>
        <af:inputText visible="false" id="dummyInputTextForOnBeforeUnloadClientListener">
                <af:serverListener type="saveBeforeLeaveEvent" method="#{Bb_Common_Template.test}"/>
            </af:inputText>
        <f:verbatim>           
      <script>
      var targetUIComponent = "";
      window.onbeforeunload = function(event)
             * Todo : add dialog logic here, in case the user wants to save
             * we do so. Else we just continue navigating.
            // if we want to save, tell the server
            var source = AdfPage.PAGE.findComponent(targetUIComponent);           
            AdfCustomEvent.queue(source,
                         "saveBeforeLeaveEvent",
                         {doSave:1},
                         true);
      </script>
      </f:verbatim>html source code in firefox
<input id="templateID:dummyInputTextForOnBeforeUnloadClientListener::content" name="templateID:dummyInputTextForOnBeforeUnloadClientListener" class=...backing bean
    public void testbis()
        FacesContext fctx =  FacesContext.getCurrentInstance();
        UIComponent uic = fctx.getViewRoot().findComponent("dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 0 " + uic );
        uic = fctx.getViewRoot().findComponent(":dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 1 " + uic );
        uic = fctx.getViewRoot().findComponent("::dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 2 " + uic );
        uic = fctx.getViewRoot().findComponent(":::dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 3 " + uic );
        uic = fctx.getViewRoot().findComponent("::::dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 4 " + uic );
        uic = fctx.getViewRoot().findComponent(":::::dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 5 " + uic );
        uic = fctx.getViewRoot().findComponent("::::::dummyInputTextForOnBeforeUnloadClientListener");
        System.out.println("With 6 " + uic );
        if (uic != null)
            String clientid = uic.getClientId(fctx);
            ExtendedRenderKitService extendedRenderKitService = Service.getRenderKitService(fctx,ExtendedRenderKitService.class);
            extendedRenderKitService.addScript(fctx,"targetUIComponent = '"+clientid + "';");
        } else {
            System.out.println("Nope didnt work...");
    public void test(ClientEvent cl)
        System.out.println(cl);
    }console output when pressing commandButton1
