PushAsync from a tab within a TabbedPage

I have a root NavigationPage. I PushAsync to a TabbedPage. One of the tabs is a ContentPage that has a Picker, and on SelectedIndexChanged I need to PushAsync another ContentPage.

This throws exception!! Is there some special way of designing navigation so I am able to push from the tab of TabbedPage that is not the root?
