Why when messages comes from broadcast the Global Message Listener is not invoked?

Spark plugin example code:

ChatManager chatManager = SparkManager.getChatManager();


GlobalMessageListener listener = new GlobalMessageListener() {


public void messageSent(ChatRoom room, Message message) {



public void messageReceived(ChatRoom room, Message message) {




I need al little help, why “messageReceived” not invoked when comes broadcasted message?

With conference or person to person everything works fine.

nobody don’t know?
