How to redirect to another page when i click on an item, in my navigation bar
提问by sfrj
I use a navigation tool called dock, from primefaces. I need to redirect to another page when i click on one of the items. The problem is that i need to find an alternative to the url attribute, this is because if i use it, the page gets redirected and the action attribute don't makes a call to the method is supposed to call.
我使用了一个来自primefaces 的名为dock的导航工具。当我单击其中一个项目时，我需要重定向到另一个页面。问题是我需要找到 url 属性的替代方法，这是因为如果我使用它，页面会被重定向并且 action 属性不会调用应该调用的方法。
This is how my nav bar looks like:
这是我的导航栏的样子：
<h:form>
<p:dock position="top">
<!--Some other menu items ...-->
<p:menuitem value="Logout" icon="unsecuredimages/logout.png" action="#{securityController.logOut}" rendered ="#{!securityController.checkLogged}"/>
</p:dock>
</h:form>
This is the backing bean that is called to do the logout. It works good the only problem is that i don't get redirected.
这是被调用以进行注销的支持 bean。它运行良好，唯一的问题是我没有被重定向。
@ManagedBean
@RequestScoped
public class SecurityController {
@EJB
private IAuthentificationEJB authentificationEJB;
public String logOut() {
authentificationEJB.releaseUserState();
return "main.xhtml";
}
...
As you see i tried to return an String form the backing bean method, but doesn't work.
如您所见，我尝试从支持 bean 方法返回一个字符串，但不起作用。
Could you help me find the way to redirect when i click on the p:menuItem?
当我点击 p:menuItem 时，你能帮我找到重定向的方法吗？
