Re: pretty url -- wrong name in js

to make it short and sweet: isn't there a working example of a custom  
viewhandler where i can look into the code?
my english isn't that good and i am not sure about the terminologies -- so  
i am afraid it will become a long and straining discussion ...

the long part:
i wrote a servlet that catches all urls of the type  
http://host/app/document/* (configured in web.xml)

public void doGet(HttpServletRequest req, HttpServletResponse res) throws  
IOException, ServletException
{
        LifecycleFactory lFactory = (LifecycleFactory)  
FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
        Lifecycle lifecycle =  
lFactory.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
        FacesContextFactory fcFactory = (FacesContextFactory)  
FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
        FacesContext facesContext =  
fcFactory.getFacesContext(getServletContext(), req, res, lifecycle);
        Application application = facesContext.getApplication();
        if(viewHandler==null) viewHandler = new  
MyViewHandler(application.getViewHandler());
        viewHandler.setActionURL(req.getRequestURI());
        application.setViewHandler(viewHandler);

        UIViewRoot view = viewHandler.createView(facesContext,  
"/presentation/document.jsf");
        facesContext.setViewRoot(view);
        TeuchosSearchBean myBean = (TeuchosSearchBean)  
application.getVariableResolver().resolveVariable(facesContext,  
"teuchosSearchBean");
        String id=req.getRequestURI();
        myBean.setObjectID(id.substring(id.indexOf("documents/")+10));

        try
        {
             
req.getRequestDispatcher(facesContext.getViewRoot().getViewId()).forward(req,  
res);
        }
        catch (Exception e)
        {
            LOGGER.error(e.getMessage(), e);
            return;
        }
}

MyViewHandler is:
class MyViewHandler extends ViewHandlerImpl
{
     private final ViewHandler myViewHandler;
     private String myActionUrl;

     public MyViewHandler(ViewHandler vh)
     {
        super(vh);
        myViewHandler=vh;
     }
     @Override
     public String getActionURL(FacesContext context, String viewId)
     {
        if(myActionUrl!=null && myActionUrl.split("/").length>4)
            return myActionUrl.replace("/documents", "");
        return myActionUrl;
     }

     public void setActionURL(String au)
     {
        myActionUrl=au;
     }
}


now every attempt to navigate from this page (by jscookmenu or  
t:commandButton) ends  with a blank page and no error.
it's most probably something very stupid -- but usually the more stupid  
the longer it takes to find out ....
