我一直在努力使其工作2周，我正尝试将BalusC的信息从这2个帖子合并到（link1

link2），以通过左侧菜单实现中心内容区域的部分页面渲染。因此，左侧的链接将使用<f:ajax>或可能<a4j:ajax>通过richfaces
通过部分页面渲染来更新中心内容

-------------------------------------------------- ----
| include1链接| |
| include2链接| 中心内容，例如include1.xhtml |
| include3链接| |
-------------------------------------------------- ----

我的page-layout.xhtml（由include1.xhtml，include2.xhtml等使用的主模板）看起来像这样。

<h:body>
    <div id="top" class="top">
        <ui:insert name="top">page-layout default top content</ui:insert>
    </div>
    <div>
        <div id="left">
            <h:form id="navigationFormId">             
                    <f:ajax render=":contentForm">                                        
                        <h:commandLink value="include1" 
                                       action="#{navigationBean.setPage('include1')}" />
                        <p></p>
                        <h:commandLink value="include2" 
                                       action="#{navigationBean.setPage('include2')}" />                    
                        <p></p>
                        <h:commandLink value="include3" 
                                       action="#{navigationBean.setPage('include3')}" />   
                        <p></p>
                    </f:ajax>                                     
            </h:form>
        </div>
        <div id="content">
           <ui:insert name="content">

                <h:panelGroup id="contentPanelGroup" layout="block"> 
                    <h:form id="contentForm">

                        <h:panelGroup rendered="#{navigationBean.page == 'include1'}">            
                            <ui:include src="include1.xhtml" />         
                        </h:panelGroup> 
                        <h:panelGroup rendered="#{navigationBean.page == 'include2'}">            
                            <ui:include src="include2.xhtml" />         
                        </h:panelGroup>
                        <h:panelGroup rendered="#{navigationBean.page == 'include3'}">             
                            <ui:include src="include3.xhtml" />         
                        </h:panelGroup>

                    </h:form> 
               </h:panelGroup>

            </ui:insert>
        </div>
    </div>
</h:body>

NavigationBean.java通过带有@Named的CDI定义为ViewScoped bean

公共类NavigationBean实现Serializable {

public NavigationBean() {}

public String getPage() {return page;}
public void setPage(String p) {page = p;}
private String page = "include1";

}

包含的页面是诸如include1.xhtml和include2.xhtml之类的文件，当单击左侧菜单链接时应将其加载到中心内容中，这是一个示例include2.xhtml

<h:body>

    <ui:composition template="page-template.xhtml">
        <ui:define name="content">

             include2

             <h:form> 
                 form components for include2
             </h:form>

        </ui:define>
    </ui:composition>

</h:body>

我正在获取FileNotFoundException，尽管堆栈跟踪无法确定是哪一个，但是删除了

<h:panelGroup rendered=".....>
    <ui:include src="..." />
</h:panelGroup>

标签可删除异常。我认为这是基于BalusC帖子中的2条来完成此操作的正确实现，但无法使其正常工作。
