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
