Mapping interface or abstract class component

Question

Please consider the following simple use case:

public class Foo 
{ 
    public virtual int Id { get; protected set; } 
    public virtual IBar Bar { get; set; }          


        

Answer 1

I haven't tried this myself but i saw an example in the fluent nh source where the lambda is cast to the concrete class:

public class FooMap : ClassMap 
{ 
    public FooMap() 
    { 
        Id(x => x.Id); 
        Component(x => (Bar) x.Bar, m => 
        { 
            m.Map(x => x.Text); 
        }); 
    } 
}

EDIT: Obviously that's exactly the same result as Sly's suggestion so that did no good. I tested it against the trunk version of fluent nh and it didn't work. It does work though if you use a many-to-one mapping:

  public class FooMap : ClassMap
  {
    public FooMap()
    {
      Id(x => x.Id);
      References(x => x.Bar).Cascade.All();
    }
  }

  public class BarMap : ClassMap
  {
    public BarMap()
    {
      Id(x => x.Id);
      Map(x => x.Text);
    }
  }

UPDATE

This was actually an easy fix. I have submitted a patch (link text) that makes Sly's solution to work.
