Error calling BeginEdit on Entity with a DateTimeOffset? Field

We have an Entity with a DateTimeOffset? field, when we call BeginEdit we are getting an error that DBNull.Value cannot be converted to DateTimeOffset? I noticed in the source code that there is no code to handle DateTimeOffset or DateTimeOffset? in CreateValueGetter() (FieldModel.cs Line 527) and CreateValueSetter (FieldModel.cs Line 715); could this be the cause of the error? There are special cases for DateTime, DateTime?, TimeSpan, and TimeSpan?

DateTimeOffset as a struct is handled as a value type (as is Nullable) so unless you are directly assigning DBNull.Value somehow there shouldn't be a problem here. Are you able to send us through a repro of this behaviour and we can have a look at whats occurring.

Thanks!

I'll try to isolate it in a project, but adding the following code resolved the issue (The same thing was done to CreateValueSetter).

 protected virtual ValueGetter CreateValueGetter()
   {
      ...
      if (typeof(DateTimeOffset?).Equals(_fieldInfo.FieldType))
      {
        var fieldGetter = Reflection.CreateGetFieldDelegate<DateTimeOffset?>(_fieldInfo);

        return target => fieldGetter(target);
      }
      ...
   }

Is there a reason that DateTime? is handled here, but DateTimeOffset? is not?

No I believe the only reason this wasn't added was because it wasn't needed, if I can confirm the problem via the repro I can look at adding this in to cover - Id like to understand the nature of the problem though first :)
