I found that add listener method all types of SessionTopicListener2(SessionTopicListenerWrapper).

In AbstractTopic.java

 public void addTopicListener(TopicListener topicListener) {
TopicListener listener = topicListener;  
if (listener instanceof SessionTopicListener) {
listener = new SessionTopicListenerWrapper((SessionTopicListener) listener);
}
listeners.add(listener);
}

and trigger it use this method.

    public void publishEvent(TopicEvent event) {
        for (TopicListener listener : listeners) {
            if (event.isAppropriateListener(listener)) {
                try {
                    event.invokeListener(listener);
                } catch (Exception e) {
                    logError(e);
                }
            }
        }
    }

the method marked blue in SessionTopicEvent.java returns false.

    @Override
    public boolean isAppropriateListener(EventListener listener) {
        return (listener instanceof SessionTopicListener);
    }

so custom listener not work, maybe "SessionTopicListener"  should be replaced by "SessionTopicListener2". I don't test it.

Richfaces guys please take a look at this. Thanks.
