RE: On the fly menu configuration ?

userMenusSorted is an ArrayList of menus that a logged in user will see.

Here is the AppUtils.createUserMenuRepository() code:

    /**
     * Return a MenuRepository, after adding the menus that user is
authorized to see.
     * Any nulls or conversion error returns null.
     * @param userMenus The List of menus that the user is authorized to
see.
     * @param mrp The application scoped MenuRepository.
     * @returns MenuRepository The MenuRepository created with user menus.
     */
    public static MenuRepository createUserMenuRepository(List userMenus,
MenuRepository mrp) {
      //Create Menu Repository and stuff it using menus that the user is
authorized and
      //application scoped MenuRepository.
      MenuRepository userMenuRep = new MenuRepository();

      logDebug.debug("AppUtils: Menu - LoadParam: "  + mrp.getLoadParam() );
      logDebug.debug("AppUtils: Menu - Name: "  + mrp.getName() );

      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("DropDown") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("Simple") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("CoolMenu") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("CoolMenu4") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("MenuForm") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("ListMenu") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("TabbedMenu") );
      userMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("Velocity") );

      Set menuNames = mrp.getMenuNames();
      for( int k = 0; k < userMenus.size(); k++ ) {
        String roleName = (String) userMenus.get(k);
        Iterator iter = menuNames.iterator();
        while( iter.hasNext() ) {
   	      String menuName = (String) iter.next();
      	  if( roleName.equalsIgnoreCase(menuName) ) {
      	  	userMenuRep.addMenu( mrp.getMenu(menuName) );
            logDebug.debug("AppUtils: MenuNames: "  + menuName );
            break;
      	  }
        }
      }

      return userMenuRep;
    }

I did not find a way to get displayers from existing (default)
Menu_Repository at application scope.
That's why, I had to hard code all displayers names and add them to new
Menu_Repository like:
newMenuRep.addMenuDisplayerMapping(
mrp.getMenuDisplayerMapping("TabbedMenu") );
