I had to add the ActivityTypeId property to make it work. I would
rather be able to do this:
public class ActivityMappingOverride :
IAutoMappingOverride<Activity>
{
public void Override(AutoMap<Activity> mapping)
{
mapping.UseCompositeId()
.WithKeyProperty(x => x.Id)
.WithKeyProperty(x => x.ActivityType,
"ActivityType_id");
mapping.PropertiesMapped.Add(typeof(Activity).GetProperty
("Id"));
mapping.PropertiesMapped.Add(typeof(Activity).GetProperty
("ActivityType"));
}
}
... and just remove the ActivityTypeId property altogether since I
shouldn't really need it.
