Problem after migrating to Xamarin.Forms 1.3

[tkowalczyk]

Hi,

According to this article: http://developer.xamarin.com/guides/cross-platform/macios/updating-xamarin-forms-apps/

I would like to use LoadApplication (new App ()); instead off SetPage(App.RootPage()); but after this
public static Action SuccessfulLoginAction { get { return new Action (() => { _NavPage.Navigation.PopModalAsync(); }); } }
application crashes because of _NavPage is probably null.

Any workarounds?

Best,
Tomek
