Re: Issue 5801: Handle Validation Groups

dear Jens,

thank you for this link. This was the code I was looking for!
If I my ask you to help me getting the final part of the puzzle (the group validation) to work properly:

I have created my own Validation Group:

public interface PrePersitValidationGroup {}

In persistence.xml I have registered this group to be called only on pre-persist:

<property name="javax.persistence.validation.group.pre-persist" value="javax.validation.groups.Default, com.emajstor.server.persistence.validator.PrePersitValidationGroup" />
<property name="javax.persistence.validation.group.pre-update" value="javax.validation.groups.Default" />
<property name="javax.persistence.validation.group.pre-remove" value="javax.validation.groups.Default" />

In my Entity I have assigned my custom validator to be a part of this group:

@UniqueUserName(groups=PrePersitValidationGroup.class, message="Username is already in use! Please choose another user name.")
private String userName;

How do I say in my CustomServiceLayerDecorator to validate PrePersitValidationGroup on pre-persit only?
Or let say: How do I take the settings from the persistence.xml into account?

class CustomServiceLayerDecorator extends ServiceLayerDecorator {
        @Override
        public <T> Set<ConstraintViolation<T>> validate(T domainObject) {
            return jsr303Validator.validate(domainObject, PrePersitValidationGroup.class);
        }
}

Thank you in advance for your help!

Best regards:

Nermin
