---------------------------------------

Sorry Segey,

I should've known better and learn how to type. I made a mistake in the mapping and this was causing it not to work. Isn't the saying "Never blame the compiler"? ;)

> Hibernate 3 has an attribute on the relation mapping elements (many-to-one, etc) called "not-found".  This attribute specifies how NHibernate should handle orpaned relationships.
> A link to Hibernate 3 docs regarding not-found:
> http://www.hibernate.org/hib_docs/v3/reference/en/html/mapping.html#mapping-declaration-manytoone
> From the docs:
> --- 
>  
> not-found (optional - defaults to exception): Specifies how cached identifiers that reference missing rows will be handled: ignore will treat a missing row as a null association.  
> --- 
>  
> I've got a ton of legacy data with orphaned relationships, and it would be _wonderful_ if I could have NHibernate NOT throw an exception and just set the reference to null.
