Hi I have this class;

[Table("tblRegions")]
   public class Region : MasterEntity
   {

public string Code { get; set; }
public string Description { get; set; }
public Region ParentRegion { get; set; }
public Country Country { get; set; }
public RegionType RegionType { get; set; }
    }

it turns out ParentRegion, Country RegionType fieds are created as foreign key fields in DB and ID values saved correctly.

Problem is on retrieving a region, the ParentRegion, Country and RegionType are returned with null values.

Any ideas why am facing this? Its frustrating me.
