Hi Guys.
As you can see I've followed "Table per subclass, using a discriminator" pattern for my mapping class.
I have 2 table in my UI: first load only the RichIndagineAI records, with only the Richiesta variables. Here no problems.
The second one load RICH_SEGNALAZIONE records with Richiesta variables plus first element of istitutoDest collection.
here what hibernate write with lazy=true
Code:
