錯誤頁面沒有顯示FullAjaxExceptionHandler

Question

我幾乎搜索了關於FullAjaxExceptionHandler的所有問題，他們都沒有解決我的問題。

那麼，我已經實現了FullAjaxExceptionHandler，但它不處理Ajax請求。如果要求不是AJAX它的工作原理確定並重定向到過期的頁面，但如果是阿賈克斯，網頁一片空白，我得到：

FullAjaxExceptionHandler: An exception occurred during processing JSF ajax request. Error page '/view/errorpages/expired.faces' will be shown. 
javax.faces.application.ViewExpiredException: viewId:/view/main.faces - A exibição de /view/main.faces não pôde ser restaurada.

附：我確定我沒有在別處手動重定向。

編輯：我嘗試過的方法與自定義ViewExpiredException

public class ViewExpiredException extends ExceptionHandlerWrapper { 

private ExceptionHandler wrapped; 

public ViewExpiredException(ExceptionHandler wrapped) { 
    this.wrapped = wrapped; 
} 

@Override 
public ExceptionHandler getWrapped() { 
    return this.wrapped; 
} 

@Override 
public void handle() throws FacesException { 

    for (Iterator<ExceptionQueuedEvent> iter = getUnhandledExceptionQueuedEvents() 
      .iterator(); iter.hasNext();) { 
     ExceptionQueuedEvent evt = iter.next(); 
     Throwable exception = evt.getContext().getException(); 
     FacesContext fc = evt.getContext().getContext(); 
     if (exception instanceof javax.faces.application.ViewExpiredException) { 

      try { 
       fc.getExternalContext().redirect("/sino/view/main.xhtml"); 
       fc.responseComplete(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } finally { 
       iter.remove(); 
      } 
     } 
    } 
    getWrapped().handle(); 
    } 

} 

它同時適用於Ajax和非Ajax請求。但我還是想用omnifaces接近

UPDATE改變一些日誌之後，我當頁面重定向後變成空白，得到了這個消息：

Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.    main.js.53 

我不認爲這是問題，但我也不知道爲什麼用FullAjaxExceptionHandler它發生並且ViewExpiredException不會。

EDIT2：現在expired.xhtml是：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml" 
    xmlns:ui="http://java.sun.com/jsf/facelets" 
    xmlns:t="http://myfaces.apache.org/tomahawk" 
    xmlns:f="http://java.sun.com/jsf/core" 
    xmlns:h="http://java.sun.com/jsf/html" xml:lang="pt" lang="pt"> 
<ui:composition> 
    <h:form> 
     <h:outputText value="View Expired" /> 
    </h:form> 
</ui:composition> 
</html> 

而且我還沒有重定向，但現在的頁面不會變成空白。該頁面停留在同一頁，我得到：

Uncaught TypeError: Cannot read property '0' of null    primefaces.js.faces?ln=primefaces:1 

也許是重定向之前的問題？

Answer 1

我刪除了一些標籤元素後，出現同樣的問題。嘗試重定向到沒有使用名稱空間的標籤來查看它是否有效的頁面。
