WELD-001303作用域类型javax.faces.view.ViewScoped没有活动上下文

问题描述

我已经切换到javax.enterprise.context.SessionScoped到javax.faces.view.ViewScoped将Face 2.1从2.1升级到2.2，以便可以将ViewScoped与我的CDI注入配合使用.

I have switched to javax.enterprise.context.SessionScoped to javax.faces.view.ViewScopedUpgraded faces 2.1 to 2.2 to be able to use ViewScoped with my CDI injections.

切换到ViewScoped后，我开始出现此错误，我不知道为什么！您认为这里有问题吗?

After I switched to ViewScoped I have started getting this error and I can't figure out why! Do you think there is something wrong here?

Glassfish 3.1.2，Primefaces 3.4.2，JSF 2.2

推荐答案

JSF 2.2需要对CDI支持进行其他更改，应使用EE 7服务器.

JSF 2.2 requires additional changes for CDI support, an EE 7 server should be used.
