Question

我收到一些抱怨，我的应用程序的p：工具栏无效。亲自查看问题发生的其中一个工作站，Firefox 49控制台出现以下错误：

SyntaxError: missing ) after argument list[Learn More]components.js.jsf:21:18950

打开components.js我可以看到文件不完整，它在这一行停止加载：

PrimeFaces.widget.Menu=PrimeFaces.widget.BaseWidget.extend ...

PrimeFaces版本是6.0.5。

我想了解两件事：

为什么会发生
如果它发生了，如何解决它应用

1）我的应用程序不向一般公众开放，因此用户将看到的第一页是登录。当我更新PrimeFaces版本时，将在登录页面上触发新版本的components.js的下载吗？我最好的猜测是用户已将他的凭据保存在浏览器上，并且他的连接速度很慢，因此当他提交登录表单时，页面甚至没有完成加载，中止components.js下载，但由于该文件存在于本地浏览器尝试使用它。

考虑到问题上存在一种模式（文件大约在中间停止加载），是否会出现服务器问题？我正在使用Apache TomEE 7.0.1（Tomcat 8.5.3）。服务器日志多次出现以下异常：

2）考虑到至少加载了jQuery，我附带了以下脚本，但它没有替换损坏的缓存文件。

    <script type="text/javascript">
        //<![CDATA[
        $(document).ready(function()                     
        {                  
            try
            {
                var ctx = "#{request.contextPath}";

                if(typeof PrimeFaces == 'undefined')
                {
                    $.getScript(ctx + '/javax.faces.resource/core.js.jsf?ln=primefaces')
                }

                if(typeof PrimeFaces.widget.TriStateCheckbox == 'undefined') // last component on the file
                {
                    $.getScript(ctx + '/javax.faces.resource/components.js.jsf?ln=primefaces')
                }       
            }
            catch(e)
            {
                console.log(e);
            }       
        });             
        //]]>   
    </script>       
</h:body>

有什么想法吗？

提前致谢

我遇到了同样的问题，因为我收到了相同的错误跟踪，并且仅在Firefox中才发生。该错误表明未加载某些字体或样式的Primefaces，但是验证了应用程序，尽管显示了此错误，但似乎一切都加载正确。经过大量研究，我发现了问题here。

日志消息与HTTP请求相对应，在服务器发送响应之前，HTTP消息在提交后立即被取消。在Firefox 59（3月13日发布）中激活了“与红色竞争”功能，这似乎是原因。

借助此功能，Firefox会同时将对缓存资源的请求发送到本地磁盘缓存和实际的网络服务器。无论使用哪个先到达的结果，都会取消另一个请求（与其他连接异常终止一样，这将导致有关“管道破损”的日志消息。）

可以通过将about:config设置为network.http.rcwn.enabled在Firefox的false中禁用此功能。因此，将其设置为false后，我停止获取日志消息。就我而言，日志消息似乎是无害的，因此可以忽略。

我希望这可以帮助遇到相同问题的其他人。
