postUserInput

public void postUserInput(java.lang.String id,
                 java.lang.Object value,
                 UserInfo ui)

Post the user Input. If there hasn't any message for this user info yet, one hashmap to hold this kind of messages will be created. Since there shouldn't be two threads trying to post for the same user info at the same time, we don't need to synchronize this.
