Hello everyone,
When does the CreateNew() method return null? This strange behavior happens regardless, whether the AppointmentsSource property is bound to a non-null collection in my ViewModel or the property is explicitly instantiated somewhere along the way (both scenarios create an instance of ObservableCollection<Appointment>).
Maybe you could give me some insight, before i start digging into my code? :)
Thanks in advance.
