Question

由于登录状态（已记录，未记录），我有一个页面加载（在panelGroup中）两个不同的页面。这是主要的开关：

template.xhtml P.S。 selector.page是默认的“主页”

<h:panelGroup layout="block" styleClass="contenitore">
    <h:panelGroup layout="block">
        <h:panelGroup layout="block" styleClass="menu_table" id="login">
            <ui:insert name="login_homepage" />
        </h:panelGroup>

        <h:panelGroup layout="block" id="content">
            <c:catch>
                <ui:include src="/#{selector.page}/#{selector.page}.xhtml" />
            </c:catch>
        </h:panelGroup>
    </h:panelGroup>
</h:panelGroup>

homepage.xhtml

<h:panelGroup rendered="#{!user.loggedIn}">
    <h:panelGroup layout="block" styleClass="content_title">
        Homepage
    </h:panelGroup>
</h:panelGroup>
<h:panelGroup rendered="#{user.loggedIn}">
    <ui:include src="/profile/profile.xhtml" />
</h:panelGroup>

login

<ui:define name="login_homepage">
    <h:form id="formLogin" prependId="false">
        <h:inputHidden value="#{selector.page}" id="page" />

        <h:panelGroup rendered="#{!user.loggedIn}">
            <h:outputScript name="jsf.js" library="javax.faces" target="head" />

            <h:outputLabel styleClass="menu_span" value="Username" />
            <h:inputText value="#{user.nickname}" id="nickname" />
            <h:outputLabel styleClass="menu_span" value="Password" />
            <h:inputSecret value="#{user.password}" id="password" />

            <h:outputLabel styleClass="menu_span">
                <h:commandButton value="Login" action="#{user.checkLogin}">
                    <f:ajax event="action" execute="nickname password page" render=":login :content err"/>
                </h:commandButton>
            </h:outputLabel>
        </h:panelGroup>

        <h:panelGroup rendered="#{user.loggedIn}">
            <h:outputLabel styleClass="menu_title" value="LOGGED" />
        </h:panelGroup>
    </h:form>
</ui:define>

profile.xhtml

<h:panelGroup layout="block" id="profileContent">
    <h:form id="formProfile">
        <h:outputScript name="jsf.js" library="javax.faces" target="head" />

        <h:panelGroup rendered="#{profileSelector.profilePage=='main'}">
            <ui:include src="/profile/profile_main.xhtml" />
        </h:panelGroup>

        <h:panelGroup rendered="#{profileSelector.profilePage=='edit' || profileSelector.profilePage=='editConfirm'}">
            <ui:include src="/profile/profile_edit.xhtml" />
        </h:panelGroup>
    </h:form>
</h:panelGroup>

ProfileSelector是@ViewScope作用域。当我加载页面并记录时，它初始化ProfileSelector bean。否则，如果我没有登录并且我进行登录，它会将内容从主页更改为配置文件，但Bean不会被初始化。那么，当我没有记录时，我怎么能对这个bean进行初始化呢？

我认为上面的代码足以理解这个问题。

Answer 2

  <c:catch>
                <ui:include src="/#{selector.page}/#{selector.page}.xhtml" />
            </c:catch>

问题是你正在使用JSTL元素，它会使@ViewScope使用替代方法。
