对象不支持此属性或方法，其中primefaces omnifaces超时组合 [英] Object doesn't support this property or method with primefaces omnifaces timeout combination
问题描述
设置：
JSF，PrimeFaces 3.2，Omnifaces 1.1，JBoss AS 7.1.1，Final，Mojarra 2.1.7
Setup: JSF, PrimeFaces 3.2, Omnifaces 1.1, JBoss AS 7.1.1, Final, Mojarra 2.1.7
我有一个简单的页面（我已经设置了omnifaces来处理ajax调用的ViewExpiredExceptions。当下面列出的页面到期并且我点击IE8上的primefaces按钮（ajax）时，过期的错误页面会显示但是出现以下javascript错误：
I have a simple page (listed below) and I have set up omnifaces to deal with ViewExpiredExceptions for ajax calls. When the listed below page expires and I click on a primefaces button (ajax) on IE8, the expired error page shows up but with the following javascript error:
消息：对象不支持此属性或方法，行：1个字符：5500代码：0 URI：blah blah / mywebapp / javax.faces.resource / primefaces.js.xhtml？ln = primefaces& v = 3.2
Message: Object doesn't support this property or method, Line: 1 Char: 5500 Code: 0 URI: blah blah/mywebapp/javax.faces.resource/primefaces.js.xhtml?ln=primefaces&v=3.2
它似乎不会在其他浏览器上产生错误。
It doesn't seem to produce an error on other browsers.
我的页面（home.xhtml）：
My page (home.xhtml):
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
template="/WEB-INF/templates/layout.xhtml">
<ui:define name="body">
<h:form id="form_search">
<p:commandButton id="idbtn1"
actionListener="#{bean.doSomething}"
value="Do something (ajax)!">
</p:commandButton>
<p:commandButton id="idbtn2" ajax="false"
actionListener="#{bean.doSomething}"
value="Do something!">
</p:commandButton>
</h:form>
</ui:define>
</ui:composition>
超时错误页面：expired.xhtml
The timeout error page: expired.xhtml
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="/WEB-INF/templates/layout.xhtml">
<ui:define name="body">
Your session has timed out.
</ui:define>
</ui:composition>
模板layout.xhtml

Web.xml还有其他位：
Web.xml has among other bits:
<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>/WEB-INF/errorpages/expired.xhtml</location>
</error-page>
<filter>
<filter-name>facesExceptionFilter</filter-name>
<filter-class>org.omnifaces.filter.FacesExceptionFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>facesExceptionFilter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
当我在到期后点击第二个按钮时，过期的页面显示没有javascript错误。
When I click on the second button after expiration, then the expired page shows without javascript errors.
任何想法？
推荐答案
这是PrimeFaces的已知问题<$在基于IE的浏览器中c $ c> update =@ all。整个视图已被 document.write（）取代，但基于IE的浏览器无法正确加载/初始化任何< script> 资源。另请参阅此 PrimeFaces论坛主题。这将针对 PrimeFaces 3.4.2版进行解决。
This is a known issue of PrimeFaces update="@all" in IE based browsers. The entire view is been replaced by document.write(), however IE based browsers doesn't properly load/initialize any <script> resources. See also this PrimeFaces forum topic. This will be addressed for PrimeFaces version 3.4.2.
在此之前，您可以使用以下JavaScript解决方法
Until then, you can workaround it using the following JavaScript
var originalPrimeFacesAjaxResponseFunction = PrimeFaces.ajax.AjaxResponse;
PrimeFaces.ajax.AjaxResponse = function(responseXML) {
var newViewRoot = $(responseXML.documentElement).find("update[id='javax.faces.ViewRoot']").text();
if (newViewRoot) {
$('head').html(newViewRoot.substring(newViewRoot.indexOf("<head>") + 6, newViewRoot.indexOf("</head>")));
$('body').html(newViewRoot.substring(newViewRoot.indexOf("<body>") + 6, newViewRoot.indexOf("</body>")));
}
else {
originalPrimeFacesAjaxResponseFunction.apply(this, arguments);
}
};
需要在 PrimeFaces拥有JS资源后加载;这可以通过在< h：body> 中引用它来完成，其中 target =head。
which needs to be loaded after PrimeFaces own JS resources; this can be done by referencing it in <h:body> with target="head".
<h:body>
<h:outputScript name="script.js" target="head">
...
</h:body>
请注意，这假设当前视图使用的是PrimeFaces组件，而这些组件又会强制自动包含 primefaces.js 和 jquery.js 脚本。否则你必须手动声明它们。
Note that this assumes that the current view is using PrimeFaces components which should in turn force auto-inclusion of primefaces.js and jquery.js scripts. Otherwise you've to manually declare them.
