NullReferenceException setting ContentView

[Marco]

Hi everybody,

I keep getting a NullReferenceException when setting the ContentView property from a navigation drawer. In my case the ContentView has to be the Content of a ContentPage. I'm getting the reference to the Content of the page, instantiating it and then passing the Content property of the page to the ContentView property of the NavigationDrawer.

I tried getting rid of the ViewModel of the content page and it seems to be working but, as you know, I need. Does anyone experienced tha same issue? Is there any workaround?

Thanks.
