How to use both Navigation Rule and f:ajax

问题

Here's my scenario: I'd like to update a page via Ajax in some cases, in other cases, execute a navigation rule. My use case is a login form. I'd like them to receive an error message via ajax if their uname/password fails, but navigate to a new page if it succeeds.

Has anyone done this using JSF2.0 f:ajax apis? I'm not really interested in solutions that go outside standard facelets, jsf2.0, etc.

回答1:

It's not different from when doing it without ajax. Just return the next view ID as String the usual way via <h:commandXxx action> (and thus not <f:ajax listener>).

So, just

<h:commandButton value="Login" action="#{bean.login}">
    <f:ajax execute="@form" render="@form" />
</h:commandButton>

with

public String login() {
    // ...

    return "nextpage";
}

will work as good as without <f:ajax>. It'll just go to nextpage.xhtml.
