页面重新加载后PrimeFaces ViewExpiredException [英] PrimeFaces ViewExpiredException after page reload

问题描述

我有包装 PrimeFaces.ajax.AjaxResponse 来处理ViewExpiredException（重新加载页面）：

I have wrapper PrimeFaces.ajax.AjaxResponse to handle ViewExpiredException (reloading the page):

var handleViewExpired = function (viewId) {
    window.alert('${msg.ajax.viewExpired}');
    window.location.reload();
};

然而，有时我在尝试点击调用AJAX请求的任何内容后反复出现该错误site：

However, sometimes I got that error over and over again after trying to click anything invoking AJAX requests on the site:

javax.faces.application.ViewExpiredException: /tree.xhtmlNo saved view state could be found for the view identifier: /tree.xhtml
    at org.apache.myfaces.lifecycle.RestoreViewExecutor.execute(RestoreViewExecutor.java:128)

我是否以错误的方式刷新？如何调用整页重新加载，例如在浏览器中单击重新加载？我是否需要删除cookie（JSESSIONID，oam.Flash.RENDERMAP.TOKEN）？

Am I doing refresh in wrong way? What should I do to invoke full page reload, such as clicking reload in browser? Do I need to remove cookies (JSESSIONID, oam.Flash.RENDERMAP.TOKEN)?

我正在使用PrimeFaces 3.5和在WebSphere 7.0上运行的MyFaces 2.0.7。 / p>

I'm using PrimeFaces 3.5 with MyFaces 2.0.7 running on WebSphere 7.0.

推荐答案

如果您在会话中同时打开了许多（> 15）页/视图/帧，那么，以下可能很有用。

If you have many (>15) pages/views/frames that are concurrently opened in the session, then, the following may be useful.

您需要查看：

1。 numberOfViewsInSession：定义支持后退按钮操作的（顶级）视图状态（页面）的数量

1. numberOfViewsInSession: defines the number of (top-level) view states (pages) to support back button operation

2。 numberOfLogicalViews：定义页面中可以显示的逻辑视图（帧）的数量（每个顶级视图）

2. numberOfLogicalViews: defines the number of logical views (frames) that can present in a page (per top-level view)

快速操作以确保它是否与将这些数字设置为500，并查看
