I'm adding MSAF using Google Analytics to a current WP7 app and I'm getting a NullReferenceException when I attempt to leave a View upon the 2nd visit. For example, I'm on a view listing items, I click on one to view the details and then hit the Back
button to return to the item list view. If I click on another item (or the same one) I get a NullReferenceException.
I can't see where the exception is happening and I get a 'No Source Available' message but the call stack location is System.Windows.Interactivity.dll!System.Windows.Interactivity.Interaction.GetBehaviors(System.Windows.DependencyObject obj) + 0x6 bytes.
The tracking is working in GA.
