Customized Top Level Navigation iView

Question

Hello to all
We are using a customized TLN iview. Its source code was modified to admit different URLs, and do the filtering depending of the default framework page which is using the TNL iview,
I mean, the TLN would be copied inside a proyect folder on the Portal Content, where would be a DFPage that contains a copy of TNL iview, and this copy would have a different roleFilter attribute.
Then, the TLN was modified again in order to merge roles that had the same name.
Those changes doesn't seem really important, they have just declared some vars, and each of them added one code line. The first one extended the first part of an IF condition, and the second one extended it with another condition, using OR.
The problem is that after the modifications, our TLN doesn't highlight correctly the first node when accessing or refreshing the Portal, instead of it shows a default start page that doesn't belong to any of our roles
The TLN iview has a procedure named PrintNavNodes, which is called on the event OnClick (I assume), and when we accessrefresh the page too.
The iview works well when clicking its buttons, it's just the first time it is used when the wrong page is shown, that's the problem we need to correct.
This procedure (PrintNavNodes) lodges the code changes. The only var modified is String prefix, so maybe anyone could tell me a default value to it, o a way to catch that mistake in order to show another page when the default page is to appear.
Also, I would appreciate if anyone knows about an API, andor a How to... manual, or any kind of documentation about this subject.
We have no possibility of reject the changes, so we need to find an alternative solution. Here is the code...
Thanks in advance, and regards
    private void PrintNavNodes(IPortalComponentRequest request, IPortalComponentResponse response)
     ILogger loggerArquitectura = request.getLogger(portal_logger);
         String strDataToPrint=;
     NavigationEventsHelperService navHelperService = (NavigationEventsHelperService)PortalRuntime.getRuntimeResources().getService(com.sap.portal.navigation.helperservice.navigation_events_helper);
     NavigationNodes initialNodes = navHelperService.getRealInitialNodes(request);       
!-- Change Heiko Broker for SiteNavigation          
          IPortalComponentContext componentContext = request.getComponentContext();
          IPortalComponentProfile profile = componentContext.getProfile();
          String roleFilter = profile.getProperty(RoleFilter);
        if(initialNodes != null)
     INavigationNode firstChild = null;
     INavigationNode firstContent = null;          
     String prefix=ROLESportal_content;
!-- Change Marta Alberto
     PROBLEM In the new TLN, when using the merge roles feature, the
     url of the merge roles is different (start with the word merge.....).
     This is a wrong implementation because it filters all the nodes that do
     not start with ROLES.
     SOLUTION Compare with the other prefix too.
     String newPrefixThatFixesTheProblem=MERGESportal_content;          
     String newPrefixThatFixesTheProblem=merge(;
            if(initialNodes.size()  0)      
            for(Iterator it = initialNodes.iterator(); it.hasNext();)
                INavigationNode initialNode = (INavigationNode)it.next();
                    strDataToPrint=initialNode.getName(),;
!-- Change Heiko Broker for SiteNavigation          
     if (initialNode.getName().startsWith(prefix+roleFilter)
!-- Change Marta Alberto

      initialNode.getName().startsWith(newPrefixThatFixesTheProblem + prefix + roleFilter))                    
                     firstContent = PrintNode(initialNode, request, response, 0);
                     if(firstChild == initialNode)

                             try
               firstContent = firstChild.getFirstChild();

               ILogger logger = request.getLogger(navigation_logger);
               if(logger != null && logger.isActive())
                    logger.severe(this, e, Exception in Top Level Navigation);
                         HttpSession httpSession = request.getServletRequest().getSession();
                         httpSession.setAttribute(NavFirstContentNode, firstContent);
            }  end FOR
        response.write(););

Hi,
Check authentication related properties of iView. Make sure all of them are set to lowest level or none
