Closing as not a Hibernate Validator issue; a corresponding ORM issue is opened under https://hibernate.atlassian.net/browse/HHH-16921

Hey thanks for reporting the issue.
We wouldn’t be able to do much on the Validator side since a test based on your example:
works fine. I have also checked if the issue can be reproduced within Hibernate ORM by running a simple test:
Works OK as well. And if Collections.singleton( b ) is replaced with a null or an empty collection – the validation is triggered and results in a constraint violation.
Hence, it seems that the problem might be in how Spring integrates Hibernate ORM.
I see that you’ve already created an HHH issue, so could you try to create a reproducer using this template and attach it to that HHH ticket so that the ORM team can look into that. If you’ll have trouble creating a reproducer using that template, you could also make your reproducer with Spring.

Hi.
I’ve a problem with entity, collection and validation.
My entities are (Getter and setter in the entities class are omitted):
I want to save the entity A.
Before saving it, i put in the bs collection some data.
I also call the validate method on A before the save and it validates without problem.
Next, i call the save method but it failes because the validation @NotEmpty on bs.
I’ve look at DefaultMergeEventListener code and i presume that the problem is at method entityIsTransient:
The first copyValues call (line 7) does not copy the bs collection from entity to copy object.
When the saveTransientEntity is called (line 9) the validation is triggered but the collection is empty.
It is a bug or a wanted behaviour?
What can i do?
Thanks
