我已经切换到 javax.enterprise.context.SessionScoped 到 javax.faces.view.ViewScoped 升级的 faces 2.1 到 2.2 以便能够在我的 CDI 注入中使用 ViewScoped。

切换到 ViewScoped 后，我开始收到此错误，我不知道为什么！你觉得这里有什么问题吗？

Glassfish 3.1.2、Primefaces 3.4.2、JSF 2.2

org.jboss.weld.context.ContextNotActiveException：WELD-001303 范围类型 javax.faces.view.ViewScoped 没有活动上下文

JSF 2.2 需要对 CDI 支持进行额外更改，应使用 EE 7 服务器。
