Hi, I have a this model :

class Question{
  Set components
  static hasMany = [components: QuestionComponent]
}

class QuestionComponent{
  static belongsTo = Question
}

class QuestionComponentStatus extends QuestionComponent{

}
class QuestionComponentOther extends QuestionComponent{

}

I want to get only QuestionComponentStatus from Set components :

questionInstance.components. ?

Thanks a lot
