Question

I have an abstract base class which inherits Sharp Arch’s Entity class:

  /// <summary>
  /// defines an entity that will ne indexed by a search crawler and offered up as full-text searchable
  /// </summary>
  public abstract class IndexedEntity : Entity
  {
    [DocumentId]
    public override int Id
    {
      get { return base.Id; }
      protected set { base.Id = value; }
    }
  }

This is to a legacy db and actually the Id column is called “HelpPageID”, so I have some mapping override as:

mapping.Id(x => x.Id, "HelpPageID");

The generated sql for querying HelpPage works fine when I simply inherit Entity. But inheriting IndexedEntity, when translated to sql, the column name override is ignored and instead Id is used for the column, thus failing.

Edit
Seems a general issue with an override as placing the override directly in the class has the same net effect

Answer 1

mapping overrides are only executed for the exact type not types which subclass the type in the mappingoverride. you have to specify an override for the subclass.
