Question

When navigating from one page to another the doesn t update in my pages. Can anyone tell me why?

The setup:

页: 1

<html
        xmlns="http://www.w3.org/1999/xhtml"
        xmlns:ui="http://java.sun.com/jsf/facelets"
        xmlns:f="http://java.sun.com/jsf/core"
        xmlns:h="http://java.sun.com/jsf/html"
        xmlns:ice="http://www.icesoft.com/icefaces/component">
    <h:head>
    <ui:insert name="stuffToInclude">
    </ui:insert>
    </h:head>
    <h:body>
    ....
    </h:body>

        </title>
    </ui:define>

    </h:head>

    </ui:define>
        .....
    </h:body>
</html>

浏览到C.jsf页就是这样:

FacesContext.getCurrentInstance().getViewRoot().setViewId("c.xhtml");

The problem is that the "TITLE" element does not update to the new title. It keeps the value from the first page that I was on before going to c.xhtml. It seems that the whole "HEAD" element isn t loaded for the new page. Suggestions?

感谢

We have now change the way we navigate to pages. Now we re using:

FacesContext.getCurrentInstance().getExternalContext().redirect(getViewId());
