Hi, I understand that this can be a performance gain by not using set, but this changes my code because I have a observer that check if a view is inserted, view.addObserver('state', this, this.viewStateDidChange), and now I can't do it, maybe is there another way to do that, but I can't figure out, @wagenet mentioned about using watch, but I can figure out. thx in advance.
