Name and version of the database you are using:
Oracle 9.2i

The generated SQL (show_sql=true):
None

Debug level Hibernate log excerpt:


In general my domain model looks as follows: I have a Class Versicherter with a persistent set of Versicherungsverhaeltnisse, which in turn hav a persistent set of Beitragsgrundlagen. All associations are maped bidirectional, all sets have a cascade of all-delete-orphan

My problem: If I insert a new Versicherungsverhaeltnis into Versicherter (and this Versicherungsverhaeltnis has new Beitragsgrundlagen) everything works as expected. However, if I use an already existing Versicherungsverhaeltnis and add a new Beitragsgrundlage, I get the above exception, when the session is implicitly flushed, when the next query is performed. However, if I explicitly flush the session, with session.flush() everything works fine again. Why do I have to flush the session? Any ideas?

When you add a new Beitragsgrundlagen, do you set both its (many-to-one) vvh and versicherter correctly?

Also, what happens if you enable cascade=save-update on both the <many-to-one> s of Beitragsgrundlagen in the hbm?

Yep, back references are set correctly.

Why would I have to enable the cascading in the reverse direction as well? As far as I understood the cascading I have a persistent Versicherter where the persistent collections are cascaded. Shouldn´t that be enough?

Yes, normally that should be enough. However, it seems that it is trying to save a BeitragsgrundlageBE which has an unsaved VersicherungsverhaeltnisBE. You could check if this is so, by setting the cascade as save-update. This is just for debugging.
