Bonjour,

J'ai une collection Rights (ISet) dans l'objet racine User et je cherche désespérément à récupérer l'objet User avec un champ supplémentaire qui est le nombre d'élément de la Collection associée.

La requête suivante ne marche pas, nhibernate impose apparemment que l'objet "usr" soit décrit via ses champs.

le HQL suivant :
Code:
select usr, count(rights) from User usr left join usr.Rights rights where usr.Name='myuser'
group by usr

ne marche pas et me donne l'exception :

System.ArgumentException: Item has already been added. Key in dictionary: 'usr' Key being added: 'usr'

Une idée ?

Merci.

Jérome
