Jsf org.primefaces.context.PrimeFacesContext.release上的java.lang.NullPointerException

我的应用程序部署到生产服务器后，总是会出现错误。在我的测试环境中，一切正常

以下是glassfish日志中的stacktrace：

我正在使用JSF2.2和PrimeFaces4.0。谢谢你的提示

看看这两个框架：

at org.primefaces.context.PrimeFacesContext.release(PrimeFacesContext.java:26)
at org.primefaces.context.PrimeFacesContext.release(PrimeFacesContext.java:28)

和源代码：

24 @Override
25 public void release() {
26     RequestContext.getCurrentInstance().release();
27
28     wrapped.release();
29 }

（参考资料：）

在我看来，好像有什么东西创建了一个

PrimeFacesContext

包装

null

，然后用另一个

PrimeFacesContext

包装它。显然，这样包装

null

是错误的，因为如果调用

release

，NPE是不可避免的

检查你的应用程序代码，看看它是否对此负责。

如前所述，JSF2.3尚未发布。Primefaces的哪个版本？Primefaces 4.0。我的意思是2.2。（输入错误）是否有faces-config.xml文件？如果是，请将这个和你的web.xml添加到问题中。。。检查它们我没有人脸配置，我在问题中添加了我的web.xml
