Hi Fabio,
Thanks for the reply. As I've said, its a very simple entity with just
an id and description. I'm converting it to a DTO object with the same
properties. So there are no relations to any other object. Below is a
sample entity and its map file that i'm trying it on.
Thanks and Regards,
Aldrich
//Entity
Public class MyEntity
{
public Guid Id {get;set;}
public string Description {get;set;}
}
//Map File
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace="Test.Domain"
assembly="Test" >
<class name="MyEntity">
<id name="Id">
<generator class="guid" />
</id>
<property name="Description" />
</class>
</hibernate-mapping>
Regards,
Aldrich
