Description

John Hall opened DATAREST-807 and commented

Hello, we setup spring Validation for our domain (data) objects in the following way with the previous SDR release:

@Configuration
public class RepositoryConfiguration implements RepositoryRestConfigurer {

    @Autowired
    private Validator validator;

    @Override
    public void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener validatingListener) {
        validatingListener.addValidator("beforeCreate", validator);
        validatingListener.addValidator("beforeSave", validator);
    }
}

This worked well because it basically turned on validation for all of our domain objects with just a few lines of code. Now it's possible that this is not the proper way to setup validation of our domains, but the documentation in this area is sparse, we found something that worked and we went with it. If this is not the proper way to setup validation for our domains, please let us know. Now with the latest Hopper release, we're seeing the following exceptions thrown with the root cause being an NPE:
