【问题描述】:
我在我的 xhtml 页面中使用了 a4j:commandButton。它工作正常。但是在会话超时之后,我可以单击该按钮,但它没有击中支持 bean 的操作方法。我想向用户显示会话已过期。我已经关注了richfaces 网站中的材料,但不知道为什么它不起作用。我将会话超时设置为 1 分钟来测试场景。
web.xml:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<context-param>
<param-name>org.ajax4jsf.handleViewExpiredOnClient</param-name>
<param-value>true</param-value>
</context-param>
<session-config>
<session-timeout>1</session-timeout>
</session-config>
Javascript:
<h:head>
<!-- (...) -->
<script type="text/javascript">
A4J.AJAX.onError = function(req, status, message){
window.alert("Custom onError handler "+message);
}
</script>
</h:head>
xhtml:
<a4j:commandButton id="submitButton"
value="Remediate Data"
action="#{addressManagedBean.submit}"
onclick="return confirm('Are You Sure?')"
styleClass="button-style" render="successMessage failureMessage infoMessage validationTMPMessage validationBOMessage">
</a4j:commandButton>
<a4j:log></a4j:log>
日志:
info [01:16:08.428]: Received 'begin' event from <input id=form12:submitButton class=button-style ...>
info [01:16:08.740]: Received 'beforedomupdate' event from <input id=form12:submitButton class=button-style ...>

我怎样才能实现我的目标?
