Hi,

I just upgraded to the latest WPF11.2 Service Release 2125.

I have date levels as follows:

HierarchyDescriptor dateTimeDescriptor = new HierarchyDescriptor { AppliesToPropertiesOfType = typeof(DateTime) };
                            int iDates = 1;
                            dateTimeDescriptor.AddLevel<DateTime>(dt => "AllPeriods", "All Periods");
                            if (IncludeYears)
                            {
                                dateTimeDescriptor.AddLevel<DateTime>(dt => dt.Year, "Years");
                                iDates++;
                            }
                            if (IncludeSemesters)
                            {
                                dateTimeDescriptor.AddLevel<DateTime>(dt => dt.SemesterShort(), "Semesters");
                                iDates++;
                            }

                            dateTimeDescriptor.AddLevel<DateTime>(dt => dt.Date, "Dates");

Also I added to default sort directions:

LevelSortDirection d = new LevelSortDirection();
                            d.LevelUniqueName = "AllPeriods";
                            d.SortDirection = ListSortDirection.Ascending;
                            flatDataSource.LevelDefaultSortDirections.Add(d);

What am I doing wrong. 

Thanks
