Navigation Crash

[jamesmontemagno]

So the issue is with:

private async void editClicked(object sender, EventArgs args)
        {
            NavigationPage editPage = new NavigationPage(new Editor(displayBody));
            //await Navigation.PushModalAsync(editPage);
            await Navigation.PushAsync(editPage);
        }

When you wrap the "Editor" in a Navigation page there is a new navigation stack.

So technically you would have to do:

var topNav = ((NavigationPage)this.Parent.Parent).Navigation;

So I would recommend just not having another navigationpage there.

I have updated a bunch of things in the final exercise 3 --. #1

Thanks James. I had been a bit over-zealous in creating new NavigationPage objects and didn’t spot what I had done. I have corrected the exercise and solution code.
