Romaric S ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiY2YzYTViOGQx... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16957?atlOrigin=eyJpIjoiY2YzYT... ) HHH-16957 ( https://hibernate.atlassian.net/browse/HHH-16957?atlOrigin=eyJpIjoiY2YzYT... ) Embeddable cannot have only one @generated field ( https://hibernate.atlassian.net/browse/HHH-16957?atlOrigin=eyJpIjoiY2YzYT... ) Issue Type: Bug Affects Versions: 6.2.6 Assignee: Unassigned Attachments: hibernate-orm-6.zip Created: 20/Jul/2023 03:45 AM Priority: Major Reporter: Romaric S ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) Using an @Embeddable with a @generated field causes the following error : org.hibernate.tuple.entity.CompositeValueGenerationException: Property of on-execution generated embeddable is not generated: child.prop1 Using the following code : @Entity public class Parent { @Id private String id; @Embedded private Child child; } @Embeddable public class Child { private String prop1; @Generated(event = {EventType.INSERT, EventType.UPDATE}) private String prop2; } Hibernate seems to be expecting all attributes (or none) to be @generated. This used to work on previous versions (tested OK on 6.1.7).
