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

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:
