title: Flux: Where should the intermediate, errors be stored?
body: <p>Flux documentation states that state should be stored in Stores. Should then the loading, saving, error messages related a entity be stored in Stores. Since View is going to get its initial State from Store hence only way to know whether its loading/saving comes from a Store.</p>
  
  <p>Also when editing a form user decides to cancel editing hence these intermediate form values should be stored in Views states rather then sent to Store?</p>
