Function that loads Questions/Comments

public function loadQuestions():void {
  Ruboss.models.reload(Question, {metadata: {creatorID: N360.models.currentUser.id, building_id: N360.models.currentBuilding.id} });
  mainViewStack.selectedChild=questions;
}

Rails Controller:

@questions = Question.all( :conditions => { :building_id.eql => params[:building_id], :creator_id.eql => params[:creatorID] }, :order => "created_at DESC" )

format.fxml  { render :fxml => @questions.to_fxml(:methods => [:question_asker], :include => {:comments => {:methods => [:comment_creator]}}) }

private function onQuestionSelect():void {
  _question = RubossUtils.clone(questionsList.selectedItem) as Question;
  ... other stuff non-relevant
}

Upon first load _question.comments.length will give the right total.  However once I click on the button again, length goes to 0, even though the log output shows the correct xml being pulled.

Bug or am I doing something wrong?
