WPF RadScheduleView RecurrenceRule

[Ohad]

Hi, 

I would be happy if you could explain to me why a regular appointment opens for editing when clicked twice but an appointment that has a recurrence does not open for me by double-clicking.
what could be the problem?

        <telerik:RadScheduleView 
            SelectedAppointment="{Binding SelectedAppointment, Mode=TwoWay}"
            EditAppointmentDialogStyle="{StaticResource CustomEditAppointmentDialogStyle}"
            AppointmentsSource="{Binding Appointments}"
            DragVisualTemplate="{StaticResource DragVisualContentTemplate}"
            DragDropHighlightStyle="{StaticResource CustomDragDropHighlightStyle}">

        public CustomAppointment SelectedAppointment { get; set; }

        public class CustomAppointment : Appointment

Would appreciate help.
