我已将javax.enterprise.context.SessionScoped切换为javax.faces.view.ViewScoped 升级面2.1至2.2,以便能够使用ViewScoped进行CDI注射。
切换到ViewScoped后,我开始收到此错误,但我无法弄清楚原因!你认为这里有什么问题吗?
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

JSF 2.2要求对CDI支持进行其他更改,应使用EE 7服务器。
