**[Bob Tiernay](https://jira.spring.io/secure/ViewProfile.jspa?name=btiernay)** commented Okay, that makes a lot of sense. Thanks for explaining

**[Bob Tiernay](https://jira.spring.io/secure/ViewProfile.jspa?name=btiernay)** commented On second thought, shouldn't there be something in the Data REST stack that translates `ConstraintViolationException` s to proper 400 responses with a payload explaining the error? Right...

**[Andrea Ratto](https://jira.spring.io/secure/ViewProfile.jspa?name=aratto)** commented I would like to see this issue accepted and fixed: I refactored a controller to be a `@RepositoryRestController` and lost request validation without any notice. In my...
