Hi all !

Like the title said , i need some help about binding Observable model :( This is what i have :

A model with INotifyPropertyChanged ( i tried before with ObservableObject from MvvmHelper James Montemagno ) image

3 buttons binded on a command that modify the properties image

The commands image

What i did : GotoAsync("ScanWorking") , select PowerKm , validate , await Shell.Current.Navigation.PopAsync(); GotoAsync("ScanWorking") , Selected button is still selected , and when i'm try to select another PowerKw , i get this error.

First time on screen , modify value , validate => ok pop Go to the screen a second time. Data seems to still be there. Click to chose another value Crash 👎
