Foreign Key is missing when trying to update List of child entity

Hibernate ORM
1

I have a complex entity with various nested levels of child entities.
Entity A contains a List of Entity B and Entity B contains a List of Entity C. When updating Entity A I get a PSQL Exception because hibernate does not pass the id of Entity B when Updating Entity C (database requires a value). With sql logging I see that it is indeed null.

Before calling Spring’s JPA save I put a breakpoint and verified that Entity C does have an instance of Entity B and Entity B does contain an id.

Any help would be greatly appreciated.

You need to add the entities, the data access code and the logs with SQL statements enabled.
