Pseudo code, it's only the concept, it probably doesn't event compile !

TrainingComponentProposal.java

Dialog trainingQuestion = new Dialog(TrainingComponentEvent.TOPIC,
                                     "Do you want to start training?",
                                     new String [] {"Yes", "No"}) {
  public void handleAnswer(int answerId) {
    IWorkingMemory memory = workingMemoryPool.get("demonstrator");
    UserAnswer answer = new UserAnswer(this.getQuestionId(), answerId);
    memory.insert(answer);
    // fact insertion will trigger the rule evaluation ...
  }
}
