ListView Sorting with Custom Groups and Custom Items

Hi,

I am having trouble sorting a ListView with Custom Items and Custom Groups.

I have Created a SortDescriptor and Enabled Sorting. I have also got a ListViewCustomComparer.

My ListViewCustomComparer is being called and it does appear to be comparing items fine but the ListView never appears sorted.

I did find this article http://www.telerik.com/forums/sorting-items which seems to describe my issue perfectly and it was deemed a problem in the ListView.

I am using version 2016.1.216.40 and was wondering if this was ever fixed and if so what might I still be doing wrong?

Thanks
