Well, you can pass a variable in the call of the previous view, and than check that value in the updateView for knowing if you came from a back button or not using the this.persist.yourvalue. If you use this you have to remenber that everytime that view is loaded from another view you have to pass that value since now the this.persist.youvalue must always be defined for not having problems, or you could cache a value with KONtx.messages.store and check that in your update view.
