Nullable property in SetSortProperty

[skttl]

Describe the bug
In the process of migrating from Konstrukt to UI Builder, it is no longer possible to use a nullable property as the sort property.

Eg. I have this collection:

                    .AddCollection<SentMailsPoco>(x => x.Id, "Sent Mail", "Sent Mails", "Sent Mails", "icon-message", "icon-message",
                        collectionConfig => collectionConfig
                            .SetNameProperty(p => p.Subject)
                            .DisableCreate()
                            .DisableUpdate()
                            .AddDataView("Sent Emails", p => p.IsSent)
                            .AddDataView("Outbox", p => !p.IsSent)
                            .AddSearchableProperty(p => p.FromName)
                            .AddSearchableProperty(p => p.FromEmail)
                            .AddSearchableProperty(p => p.ToName)
                            .AddSearchableProperty(p => p.ToEmail)
                            .AddSearchableProperty(p => p.Body)
                            .SetSortProperty(p => p.SentUtcDate, SortDirection.Descending)
                            .ListView(listViewConfig => listViewConfig
                                .AddField(p => p.FromEmail)
                                .AddField(p => p.FromName)
                                .AddField(p => p.ToEmail)
                                .AddField(p => p.ToName)
                                .AddField(p => p.CreatedUtcDate)
                                .AddField(p => p.SentUtcDate)
                                .SetPageSize(100))

It complains that SentUtcDate is nullable.

This used to work in Konstrukt. How can I make it work in UI Builder (13.1.7)?

Additional context
Add any other context about the problem here.

Same thing for nullable fields when adding fieldsets to an editor eg.

                            .Editor(editorConfig => editorConfig
                                .AddTab("General", tabConfig => tabConfig
                                    .Sidebar(sidebarConfig => sidebarConfig
                                        .AddFieldset("Metadata", fieldsetConfig => fieldsetConfig
                                            .AddField(p => p.Id).MakeReadOnly()
                                            .AddField(p => p.IsSent).MakeReadOnly()

Hi @skttl ,

Could you give me more details on the issue you're experiencing? I've tried replicating locally, and both sorting and editor use cases were fine.

Thanks,
Adrian
