这是问题： 我们有包含xhtml包含表单的主页面。 commandButton调用action，但是scoped bean没有按inputText的值填充。代码如下：
welcome_file.xhtml
<h:head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>XHTML Page</title>
<h:outputStylesheet name="CSS/style.css" />
</h:head>
<h:body>
<f:facet name="last">
<link rel="stylesheet" type="text/css" href="#{facesContext.externalContext.requestContextPath}/resources/CSS/style.css" />
<h:outputStylesheet name="CSS/style.css" />
</f:facet>
<f:view contentType="text/html" id="fview">
<p:layout fullPage="true" resizeTitle="resize">
<p:layoutUnit position="north" size="68" id="north" style="font-size: 100%; text-align: center;" header="КРАУДСОРСИНГОВАЯ ПЛАТФОРМА MEPHORCE">
<h:outputText value="#{clientBean.clientFIO.get(0)} #{clientBean.clientFIO.get(1)} #{clientBean.clientFIO.get(2)}" style="font-size: 100%; text-align: left;"/>
</p:layoutUnit>
<p:layoutUnit position="west" id="west" resizable="false" header="Меню" style="height:580px;overflow:hidden;" size="225">
<h:panelGroup id="menu" layout="block">

<f:ajax render=":content">

<li><h:commandLink value="Сообщество" action="#{beanClient.setPage('community')}" /></li>
<li><h:commandLink value="Выход" action="#{clientBean.logout()}" /></li>
</ul>
</f:ajax>
</h:form>
</h:panelGroup>
</p:layoutUnit>
<p:layoutUnit styleClass="layoutUnitCenter" position="center">
<h:panelGroup id="content" layout="block">

<p:layoutUnit position="south" resizable="true" id="south">

</p:layout>
</f:view>
</h:body>

答案 0 :(得分：0)
您使用的是clientBean和beanClient，哪一个是正确的？我相信这会导致您的JSF页面混淆并可能启动两个不同的bean（或至少抛出一些未发现的异常）。结果导致页面控制/数据问题。
