重定向作爲響應Ajax請求結束返回空

Question

我們使用Primefaces 3M4和我們的頁面中的一個具有p：dataTable的，它使用的事件Ajax調用：

<p:ajax event="rowSelect" update=":newsForm:newsDlg" oncomplete="newsDlg.show();"/> 

當會話超時頁面被重定向到/login.xhtml，它適用於非ajax動作（菜單項等），但是當我在數據表中選擇一行後會話過期，頁面不會更改爲登錄頁面，並且在Firebug中，我看到以下內容：

根據dashboard.xhtml螢火蟲的標題部分

在dashboard.xhtml響應

<?xml version='1.0' encoding='ISO-8859-1'?> 
<partial-response><changes><update id="javax.faces.ViewState"><![CDATA[-3728406524126180805:2441995557020829808]]></update></changes></partial-response> 

在dashbaoard.xhtml後

在login.xhtml的XML部分

XML Parsing Error: no element found Location: moz-nullprincipal:{6ccf85cf-5c69-438c-a9bb-e66423a36a48} Line Number 1, Column 1: 

^

響應代碼

HttpServletResponse servResponse = (HttpServletResponse) response;     
servResponse.sendRedirect("login.xhtml"); 
servResponse.setHeader("Access-Control-Allow-Origin", "*"); 

Answer 1

我找到了這個問題的答案in this blog

與在doRedirect方法的博客文章底部的相關代碼。

Answer 2

只是guess--

如果你想重定向從ajax響應，你可以不這樣做301/302風格 - 你必須發回消息給瀏覽器，並通過JavaScript重定向瀏覽器。

可能非阿賈克斯人的工作，因爲他們使用301/302s。
