Using Projections.Concat inside a Projections.Conditional

[xanatos]

I want to use a Projections.Concat inside of a Projections.Conditional. The problem is that Projections.Concat returns a string instead of a IProjection. ** I DO KNOW I COULD USE Projections.SqlFunction ** . I have tried using Projections.Property but it didn't work:

var name = s.QueryOver<Person>(() => person)

            .Where(p => p.Name == "p1")

            .Select(Projections.Conditional(

                Restrictions.Where(() => person.Name != ""),

                Projections.Property(() => Projections.Concat(person.Name)),

                Projections.Property(() => person.Name)

            ))

            .SingleOrDefault<string>();

I even tried Projections.Constant but it didn't work.

Thanks
