Hi All
I'm attempting to use an HQL query in element to load an entity based on other entities.
My class is as follows
public class ParentOnly
{
public ParentOnly(){}
public virtual int Id { get; set; }
public virtual string ParentObjectName { get; set; }
}
and the
mapping looks like this
<class name="ParentOnly">
<id name="Id">
<generator class="identity" />
</id>
<property name="ParentObjectName" />
<loader query-ref="parentonly"/>
</class>
<query name="parentonly" >
select new ParentOnly()
from SimpleParentObject as spo
where spo.Id = :id
</query>
The class that I am attemping to map on top of is SimpleParentObject, which has its own
mapping and can be loaded and saved without problems.
When I call session.Get(id) the sql runs correctly against the SimpleParentObject table, and the a ParentOnly
object is instantiated (as I can step through the constructer), but only a null comes back, rather than the instantiated ParentOnly
object.
I can do this succesfully using a instead of the HQL, but am trying to build this in a database independent fashion.
Any thoughts on how to get the and elements to return a populated ParentOnly
object...?
Thanks
Matt
