Richfaces push CDI

[carabou]

Hello,

I'm trying to reproduce Richfaces showcase about CDI push :

http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=push&sample=pushCdi&skin=blueSky

I've copied the given source code but I'm getting the following exception when I launch the consumer xhtml page :

java.lang.IllegalArgumentException: Subtopic name '' does not match pattern ([a-zA-Z0-9_]+|#\{.+\})

          at org.richfaces.application.push.TopicKey.<init>(TopicKey.java:76)

          at java.lang.Thread.run(Thread.java:619)

And nothing is displayed.

Why the subtopic name is found empty ? It is initialized like this :

      @Inject

    @Push(topic = PUSH_CDI_TOPIC, subtopic = "#{pushBean.userIdentifier}")

    Event<String> pushEvent;

    @PostConstruct

    public void initialize() {

        if (userIdentifier == null) {

            userIdentifier = getUUID().replace("-", "");

        }

    }

Thanks for your repplies.
