org.omnifaces.cdi.push.SocketChannelManager$ViewScope 无法转换为 com.sun.faces.push.WebsocketChannelManager$ViewScope
org.omnifaces.cdi.push.SocketChannelManager$ViewScope cannot be cast to com.sun.faces.push.WebsocketChannelManager$ViewScope
它是 my previous question 的后续，可能是由于 Mojarra 2.3.9 中的错误，我无法使 f:websocket 工作。
我想再试一次 o:socket。
我的依赖项包括：
- Tomcat 8.5.42
- Mojarra 2.3.9
- OmniFaces 2.7.5
- 焊接 2.4.8.Final
连接已打开，但是当我从 bean 发送消息时，没有任何反应。

如果您在 bean 中将 javax.faces.push.Push instead of org.omnifaces.cdi.Push 作为 @Push 导入，就会发生这种情况。
仔细检查您的导入。在 JSF 2.3 环境中使用 OmniFaces <o:socket> 时，确保 @Push 和 PushContext 是从 org.omnifaces.* 包而不是 javax.faces.* 包导入的，因为 @Push 和 PushContext 是从 javax.faces.* 包导入的，因为 class 名字。
