Question

使用BalusC回答有关处理JSF ajax异常的多个问题我尝试过：

omnifaces.FullAjaxExceptionHandler
自定义处理程序

结果始终相同 - 对ajax事件期间的任何异常的响应是页面如下所示：
常规h:commandButton重定向到登录页面的例外情况。这很奇怪，因为应该重定向到404.xhtml

反正：这是我的web.xml：

<error-page>
        <error-code>404</error-code>
        <location>/errors/404.xhtml</location>
    </error-page>
    <error-page>
        <error-code>500</error-code>
        <location>/errors/404.xhtml</location>
    </error-page>
    <error-page>
        <exception-type>javax.faces.application.ViewExpiredException</exception-type>
        <location>/errors/404.xhtml</location>
    </error-page>

这是我的customExceptionHandler：

@Override
    public void handle() throws FacesException {

        final Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator();

        while (i.hasNext()) {
            ExceptionQueuedEvent event = i.next();
            ExceptionQueuedEventContext context
                    = (ExceptionQueuedEventContext) event.getSource();

            // get the exception from context
            Throwable t = context.getException();

            final FacesContext fc = FacesContext.getCurrentInstance();

            //here you do what ever you want with exception
            try {

                //log error ?
                logger.info("error thrown {}", t);

                //redirect error page
                fc.getExternalContext().redirect("http://www.o2.pl");
                fc.renderResponse();

                // remove the comment below if you want to report the error in a jsf error message
                //JsfUtil.addErrorMessage(t.getMessage());
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                //remove it from queue
                i.remove();
            }
        }
        //parent hanle
        getWrapped().handle();
    }

加上我的服务器（wildfly 9.0.0）日志只有从customExceptionHandler记录的这条消息： (default task-104) error thrown {}: javax.faces.application.ViewExpiredException: viewId:/login.xhtml - View /login.xhtml could not be restored. at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:212) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:123) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:198) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:658) at io.undertow.servlet.handlers.ServletHandler.handleRequest(ServletHandler.java:86)

我再次切换到omnifaces.FullAjaxExceptionHandler，这是服务器日志： [org.omnifaces.exceptionhandler.FullAjaxExceptionHandler] (default task-27) FullAjaxExceptionHandler: An exception occurred during processing JSF ajax request. Error page '/errors/404.xhtml' will be shown.: javax.faces.application.ViewExpiredException: viewId:/login.xhtml - View /login.xhtml could not be restored.

所以问题是一样的。
另外这是页面的样子：

据我所知，两个处理程序都被正确解雇，但不知何故，他们的响应已被破坏所以最大的问题是 - 我做错了什么？我错过了什么？

编辑BalusC的项目描述

这是我的项目结构：

和我的web.xml的另一部分定义安全性：

 <security-constraint>
        <web-resource-collection>
            <web-resource-name>Secure assets</web-resource-name>
            <url-pattern>/secure/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>WRITER</role-name>
        </auth-constraint>
    </security-constraint>

    <login-config>
        <auth-method>FORM</auth-method>
        <form-login-config>
            <form-login-page>/login.xhtml</form-login-page>
            <form-error-page>/login.xhtml</form-error-page>
        </form-login-config>
    </login-config>

编辑错误来源

将错误附加到按钮的ajax：

<h:commandLink value="#{msg.add}">
   <f:ajax render=":addingModalBody"
           execute="@this"
           listener="#{myBean.setFields()}"
           onevent="renderAddModalBody"/>
</h:commandLink>

此按钮的目标是在模态（渲染）的值渲染体上显示辅助bean（侦听器）的值，并显示模态（onevent）。

JSF ajax异常处理程序无法正常工作
