WELD-001303：Websphere 上没有范围类型 javax.enterprise.context.SessionScoped 的活动上下文
WELD-001303: No active contexts for scope type javax.enterprise.context.SessionScoped on Websphere
我们已升级我们的应用程序以使用 CDI bean。当我们在 Wildfly 10.x 上部署我们的应用程序时，这种变化非常顺利，但是当我们尝试在 Websphere Classic 和 Liberty 上部署相同的应用程序时，出现了一些问题。
我们已经寻找了几个已经发布在这里的问题，例如 this, this, this or this，但是 none 的答案能够解决我们的问题。
在我的本地主机上，我使用带有 webProfile-7.0 的 Websphere Liberty Profile，即 CDI-1.2、EL-3.0、JSF-2.2 和 servlet-3.1。
我们的应用程序还使用 Primefaces 6.0.
phaseListener 出现问题。在其上，我们正在注入一个同时注解了 @Named (javax.inject.Named) 和 @SessionScoped (javax.enterprise.context.SessionScoped) 的 Bean。
当在 phaseListener 上调用注入的变量时，会抛出以下错误。

我也试过添加
FacesContext context = event.getFacesContext();
WebSession webSession = context.getApplication().evaluateExpressionGet(context, "#{ws}", WebSession.class);
在 if 语句之前，使用 webSession 而不是 ws，但得到了同样的错误。
我想再次指出，这在 Wildfly 中运行良好，这让我们假设我们正确地实现了代码。此外，我们确定我们正在使用 Java 8 并且服务器支持 JEE7，因此，从我们看过的所有地方来看，我们假设这应该在我们的 Websphere 版本上得到支持。
在 Websphere Classic 9.0 上部署应用程序时，我们遇到了完全相同的问题。
到目前为止我们发现的唯一区别是 Websphere 使用 Myfaces 而 Wildfly 使用 Mojarra。这可能是 Myfaces 中的某种错误吗？我们需要使用任何特定的配置或代码来支持这种事情吗？
如果您需要有关我们实施的更多信息以帮助查明此问题的原因，请告诉我。
跟进这个问题已经晚了 4 年，但是，如果其他人发现它，解决方案应该是在 WebSphere 上将 deferServletRequestListenerDestroyOnError 设置为 true。
或者，如果您使用的是 Liberty，只需将此添加到 server.xml：
