Composite-ID Child Cascade all delete-orphan

[save2king]

Ciao a tutti, ho un problema con nhibernate da diverso tempo e non sono mai riuscito a risolvere, provo a descrivere in modo chiaro il problema.
Vorrei salvare e modificare una lista di oggetti collegati tramite FK all'oggetto padre in cascata utilizzando le funzionalità di NHibernate.
Non riesco a capire dove sbaglio, chi può aiutarmi?

Le tabelle sul DB sono:

Ciao Salvatore, 

Con identity "Assigned" c'è sempre qualche grattacapo. :-)
Prova a dare un'occhiata qui: 

https://stackoverflow.com/questions/1070311/how-to-save-a-child-with-assigned-id-in-nhibernate

C'è qualche suggerimento utile perla tua situazione.

HTH,

Alberto
