我正在使用richfaces 4.2并尝试创建推送系统。richfaces push（4.2）
<a4j:push address="[email protected]">
<a4j:ajax event="dataavailable" render="list" execute="@none" />
</a4j:push>
public void push() throws MessageException {
TopicKey topicKey = new TopicKey("topic");
TopicsContext topicsContext = TopicsContext.lookup();
topicsContext.publish(topicKey, "empty message");
System.out.println("push event");
}
，但在客户端上呈现的JavaScript似乎有一个问题：
它尽量的让下面的网址
/rfRes/org.richfaces.resource.PushResource.html?__richfacesPushAsync=1&pushSessionId=1df3c2e1-37a2-4e96-993a-c881597e8cb2&_=1334760087852
但缺少“pushTopic” - 获得PARAM结果如下：

有没有人知道我在做什么错？
编辑： 我使用tomcat7
我试图改变我的bean：
@Autowired
@Push(topic = "topic", subtopic = "subtopic")
// now Topic getting initialized with this.
private Event<String> pushEvent;
public void push() throws MessageException {
pushEvent.fire("hello");
}
但后来我得到
