title: Richfaces 4 and a4j:push in Seam
body: <p>I just upgraded from Richfaces 3.3.3 to 4.2.2 and from Seam 2.2.2 to Seam 2.3 on my JBoss AS 7. At the moment it works good.</p>
  
  <p>But I must use the Tag: a4j:push and I have no idea how to bind a seam component to this one.</p>
  
  <p>What i have:</p>
  
  <pre><code>@Name(TestBeanInterface.NAME)
  @JndiName(value=TestBeanInterface.JNDI_NAME)
  @Scope(ScopeType.SESSION)
  public class TestBean implements Serializable {
  
  private static final String CDI_PUSH_TOPIC = "pushCdi";
  
  private String userIdentifier;
  
  @Inject
  @Push(topic = CDI_PUSH_TOPIC, subtopic = "#{testBean.userIdentifier}")
  private javax.enterprise.event.Event&lt;String&gt; pushEvent;
  
  @PostConstruct
  public void init() {
      System.out.println("hey");
  
      if (userIdentifier == null) {
          userIdentifier = UUID.randomUUID().toString().replace("-", "");
      }
  
      TopicsContext topicsContext = TopicsContext.lookup();
      topicsContext.getOrCreateTopic(new TopicKey(CDI_PUSH_TOPIC, userIdentifier));
  }
  
  public void sendMessage() throws Exception {
      System.out.println("Send Message");
      pushEvent.fire("a test message");
  }
  
  public String getUserIdentifier() {
      return userIdentifier;
  }
  
  public void setUserIdentifier(String userIdentifier) {
      this.userIdentifier = userIdentifier;
  }
  }
