使用MenuModel支持的菜单进行Primefaces布局导航

Question

Using PrimeFaces, I want to update/refresh a pages central layout unit based on user interaction with a menu (programmatically created MenuModel) that's included in the same pages east layout unit. From what I can tell, this is not possible, but very well could be wrong. Thanks!

subMenu = new Submenu();
subMenu.setLabel("Sales");  
subMenu.setIcon("ui-icon ui-icon-home");

-

private String currentPage; //holds identifier of current content panel

-

<!-- navigation panel -->
<p:layoutUnit position="west" resizable="false" size="216">
    <ui:include src="./includes/navigationMenu.xhtml" />
</p:layoutUnit>  

<!-- content panel -->
<p:layoutUnit position="center">
    <ui:include src="/views/#{navigationBean.currentPage}.xhtml" />         
</p:layoutUnit>

Thanks!

Answer 1

It's just a question: Why do you create a menu programmatically?

Other than that almost everything it's possible: try to include the ui:include into a form component with an id (let's say myFormId ) and try to update this form every time a submenu item is selected; Ok so let's do that programmatically:

MenuItem item = new MenuItem();
item.setValue("Dynamic Menuitem");
item.setUrl("#");                    //add whatever attribute you want to menuItem
item.setUpdate("myFormId");
subMenu.getChildren().add(item);     //then add the menuItem object to subMenu as a child.

You can find here the menuItem API

I implemented a listener..

MenuItem thisItem = (MenuItem)event.getComponent();
String navigateTo = thisItem.getId();
BeanManager beanManager = new BeanManager();
NavigationBean navBean = (NavigationBean)beanManager.get("navigationBean");
navBean.setCurrentPage(navigateTo);

added it to the MenuItem as well as a call to the the templates refresh()...

item.addActionListener(new MenuItemListener());
item.setOnsuccess("refresh()");

added the refresh method...

function refresh(){
    document.location="#{request.contextPath}/faces/views/main.xhtml";
}

I really don't care for this solution, but it's better than the alternative, having untestable menu creation logic in markup.
