问题 I just updated to Nativescript 2.2.0, everything built fine and runs fine through most of my app. When loading a specific view though I get the below unhandled exception along with the stack trace. This was not occuring before updating the core platform and modules. When I search for the 'disableNotifications' property mentioned in the stack trace I find nothing of the sort in my project.
