Removing TimeSpan Filter from UI throws NullReferenceException

[Radiation]

Hi,

I have a RadDataFilter whose Source property is bound to ObservableCollection and AutoGenerateItemPropertyDefinitions is set to false:

            <telerik:RadDataFilter Name="radDataFilterSessions" Margin="-15,0,0,0"
                               MaxWidth="600" AutoGenerateItemPropertyDefinitions="False"
                               Source="{Binding DomainContext.Sessions}">
            </telerik:RadDataFilter>
            
Properties to filter are manually defined:
            
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Name", typeof(string), "Name"));
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Description", typeof(string), "Description"));
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Recorded", typeof(DateTime), "Recorded"));
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Duration", typeof(TimeSpan), "Duration"));
            
There seems to be problem with Duration (TimeSpan) property. I can add filter item with this property. I can change value and filter, but when I try to remove this filter item (remove a filter by using RadDataFilter's UI remove button), I got NullReferenceException:

No problems with String and DateTime properties. I am using 2013.2.611.45 build.

Hi,

We have fixed this issue right away. It will be working properly with the next Latest Internal Build.
