Most of all times (not all), I need to tap on the screen somewhere to force the rebuild of my page...
I have a listview. I select an element of the listview, do some stuffs, update database, update appstate...
Go back from element to listview. Force rebuild the page of the listview. I see with visual studio that it's updating the appstate and pageState... but if I don't touch my screen, it's not updating
