首先生病解释我尝试做什么,我有一个index.xhtml页面,其中我包含menu.xhtml与菜单的菜单,在menu.xhtml中有一个面板id = contenido,我想根据menuitem点击更新,我已经获得更新该面板,但问题是,当我更新到另一个页面,例如在默认情况下是home.xhtml和我更新到enviarsol.xhtml然后enviarsol.xhtml的命令按钮不起作用,我新的在这和我已经尝试了一些不同的更新面板的方法,我认为问题是enviarsol.xhtml的bean没有被管理或类似的东西,我也这样做,因为我想只刷新那个面板,而不是所有的页面,有人帮我请。

index.xhtml:

<h:form>
    <img src="resources/homeheader.jpg" width="300" height="113" alt="homeheader"/>
    <div style="background-color: white">
    <img src="resources/Logos.jpg" width="1024" height="166" alt="homeheader"/>
    </div>
     <p:panel id="centerpage" >
        <ui:include src="WEB-INF/menu.xhtml"/>
    </p:panel>
</h:form>`

menu.xhtml:

<p:menuitem value="Contactos" icon="ui-icon-arrowreturnthick-1-w" actionListener="#{bnmenu.btnEditarContacto(e)}" update="contenido"/>  
<p:panel id="contenido" >
    <ui:include  src="#{bnmenu.url}"/>
</p:panel>

bnmenu.java:

private String url;

public bnmenu() {
    url="home.xhtml";
}

 public void btnEditarContacto(ActionEvent e)
{
  url="enviarsol.xhtml";
}

home.xhtml:

<p:panelGrid columns="2" style="border-width: 0px">
        <p:commandButton  value="Consultar" actionListener="#{bnhome.btnlogin(e)}" update="txt1"/>
    <p:inputText id="txt1" value="#{bnhome.txtUsuario}"/>
    </p:panelGrid>

enviarsol.xhtml:

<p:panelGrid columns="2" style="border-width: 0px">
        <p:outputLabel for="txtcorreo" value="Correo: "/>
        <p:inputText id="txtcorreo" value="#{bnSolicitud.correo}"/>
         <p:outputLabel for="txtmensaje" value="Mensaje: "/>
         <p:inputText id="txtmensaje" value="#{bnSolicitud.mensaje}"/>
         <p:commandButton  value="Enviar" actionListener="#{bnSolicitud.btnSolicitar(e)}" update="messages"/>        
</p:panelGrid>`

i included this:

我包括这个:

<context-param> 
    <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name> 
    <param-value>false</param-value> 
</context-param>

and now it is working but i dont know what more effects will this cause well now it works but only once when i click in commandbutton from enviarsol.xhtml Finally it appears working fine, i changed @RequestScoped by @SessionScoped in bnmenu

现在它正在工作,但我不知道更多的效果将导致现在它的工作,但只有一次,当我从enviarsol.xhtml点击命令按钮最后它似乎工作正常,我改变@RequestScoped由@SessionScoped在bnmenu

Are you sure that you really want ajax navigation? It is very frustrating for a user not being able to use the browsers urlfield or navigation buttons, and it will be harder for you to code aswell. Consider transforming index.xhtml into a template file as described at http://www.mkyong.com/jsf2/jsf-2-templating-with-facelets-example and using normal navigation.
