clone(feedback) {
    let cloned  = [];
    for (var i = 0; i < feedback.length; i++) {
      let fb = new Model.OnmsSituationFeedback();
      fb.situationKey = feedback[i].situationKey;

      fb.tags = feedback[i].tags;
      fb.user = feedback[i].user;
      cloned.push(fb);
    }
    return cloned;
  }
