Closing this as the issue is most likely out of date already as generators have been completely reworked in Hibernate ORM 6. If this is still an issue for you, please create a new Jira and attach a test case working against the latest Hibernate ORM version that reproduces the problem.

Sure, Vlad. I will go a little deeper and come back with an analysis.

@Ganapathi Basimsetti I'm not sure whether it's easy to implement. You should try it anyway as it's going to be a very useful experience anyway.

Hi Vlad,

I too got the same exception and the usage is also the same. I am looking at the EntityMetaModel class where the exception is occurring. I want to work on this one if someone else is not working. I consider myself a beginner in Hibernate, so do you think this can be done by a beginner?

Thanks. You could also try to implement it if it’s urgent to you.

Otherwise, you could use @PrePersist and @PreUpdate to emulate the @CreationTimestamp and @UpdateTimestamp behavior. Check out this article for more details.
