Hi,
would like check if anyone has encountered this
before.
i basically want to display menu items in a particular
order. the menu items are stored in a database. I
followed the online example. I deliberatly store the
menu items into the database according to the view
sequence. The resulted list of items show the corrent
sequnce. However, when jsp renders the topMenus, it
seems that it order is not what I stored in the
database (the sub menu items are all correctly
displayed in each top menu).
SQL query menu database:
------------------------
"from Menu p order by p.id asc"
in my StartupListener:
----------------------
MenuRepository defaultRepository = (MenuRepository)
context.getAttribute
(MenuRepository.MENU_REPOSITORY_KEY);
MenuRepository repository = new MenuRepository();
repository.setDisplayers(defaultRepository.getDisplayers());
MenuManager mgr = (MenuManager)
ctx.getBean("menuManager");
List menus = mgr.getMenus();
for (int i=0; i<menus.size();i++) {
MenuComponent mc = new MenuComponent();
Menu m = (Menu) menus.get(i);
BeanUtils.copyProperties (mc, m);
String parent = m.getParentName();
if(parent != null) {
MenuComponent parentMenu =
repository.getMenu(parent);
if (parent == null) {
parentMenu = new MenuComponent();
parentMenu.setName(parent);
repository.addMenu(parentMenu);
}
mc.setParent(parentMenu);
}
repository.addMenu(mc);
}
context.setAttribute("menuRepository", repository);
in my jsp file:
----------------
<menu:useMenuDisplayer name="ListMenu"
repository="menuRepository">
<c:forEach var="menu"
items="${menuRepository.topMenus}">
<menu-el:displayMenu name="${menu.name}"/>
</c:forEach>
</menu:useMenuDisplayer>
I am not sure how to control the <c:forEach> with
menuRepository so that it displays the topMenu in my
intended order.
thanks
li xin
