java - Richfaces 4 と a4j:push in Seam

Question

JBoss AS 7 で Richfaces 3.3.3 から 4.2.2 に、Seam 2.2.2 から Seam 2.3 にアップグレードしました。

しかし、タグ: a4j:push を使用する必要があり、これに seam コンポーネントをバインドする方法がわかりません。

私が持っているもの:

@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<String> 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;
}
}

これらは、最終的にプッシュ作業を開始した後、Richfaces フォーラムに書いたメモです。ざっと目を通して、これが役立つかどうかを確認してください。

サーブレット v3 コンテナー (web.xml: web-app version="3.0") を使用しているため、プッシュサーブレットを web.xml で明示的に宣言する必要はありません。
web.xml で PushFilter の例をいくつか見たことがありますが、これは間違いなく問題の原因であり、これを削除して初めて機能しました。

これを web.xml で使用することが提案されているのを見てきましたが、必要はありませんでした:

<context-param>
   <param-name>org.richfaces.push.handlerMapping</param-name>
   <param-value>/__richfaces_push</param-value>
</context-param>

0.8.0-RC1 より後の (含まれていない) Atmosphere バージョンに問題があるようで、WebSocket の NoClassDefFound エラーが発生します (とにかくそのようなもの)。最新バージョン 0.8.2 は動作しません。
java ファイル内の topicContext に関連する行が必要です。これが原因で、「トピック 'トピック名' が構成されていません」というエラーが発生します。これらはショーケースの例にはありませんが、コンポーネントガイドで参照されています。

        Log.log("sendMessage");
        pushEvent.fire("a test message");
    }

    // add getters & setters
