I have a MasterDetailPage and the detail of it is a tabbedpage. I am navigating to the tabbed page with the uri "MasterDetailPage/NavigationPage/TabbedPage". In the tabbed page I invoke the OnNavigatingTo Event for all of its children with PageUtilities.OnNavigatingTo. In a page of the tabbedpage i navigate to another page via the uri "SecondPage" and useModalNavigation to false. My problem is that while the OnNavigatingTo Event of the "SecondPage" is invoked, the OnNavigatedFrom is never called. May i messed up with the navigation or is there something else i could try?
