Bug in recurrence pattern?

[Håkan]

Hi!

I have styled some special slots to display saturdays and sundays with a different background color in the month view.
But in the last week of the year, the special slots are not drawn, see attaced image.
It does not matter if the year ends on a sunday or not, its always the last week that is missing.

I have tried with and without the RecursUntil property with no result.

This is my code:

public static ObservableCollection<Slot> SetupSpecialSlots(bool readOnly, DateTime? start = null, DateTime? end = null)
        {
            ObservableCollection<Slot> specialSlots = new ObservableCollection<Slot>();

            if (!start.HasValue)
                start = CalendarUtility.GetFirstDateOfYear();
            if (!end.HasValue)
                end = CalendarUtility.MergeDateAndTime(CalendarUtility.GetFirstDateOfYear(), new TimeSpan(23, 59, 59));

            Slot slot = null;

            slot = CreateSpecialSlot(new SaturdayOccurence(), start.Value, end.Value, readOnly);
            slot.RecurrencePattern = new RecurrencePattern(null, RecurrenceDays.Saturday, RecurrenceFrequency.Weekly, 1, null, null);
            specialSlots.Add(slot);

            slot = CreateSpecialSlot(new SundayOccurence(), start.Value, end.Value, readOnly);
            slot.RecurrencePattern = new RecurrencePattern(null, RecurrenceDays.Sunday, RecurrenceFrequency.Weekly, 1, null, null);
            specialSlots.Add(slot);

            return specialSlots;
        }

        public Style ReadOnlyStyle { get; set; }
        public Style SaturdayStyle { get; set; }
        public Style SundayStyle { get; set; }

        public override Style SelectStyle(object item, DependencyObject container, ViewDefinitionBase activeViewDefinition)
        {
            if (item is DefaultOccurence)
                return this.DefaultStyle;
