Implement ConstraintValidator<Email, Collection<String>> -------------------------------------------------------- Key: HV-264 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-264 Project: Hibernate Validator Issue Type: New Feature Components: validators Affects Versions: 4.0.1 Environment: Linux Reporter: Michenaud Laurent Fix For: 4.1.0 Hi, I have a list of String in my bean : These strings are email and i want to validate them. So, i did in my bean : @NotEmpty @Email //@Valid <= uncommenting that line doesnot change anything. List<String> emails ; At execution, i've got the error : Exception in thread "main" javax.validation.UnexpectedTypeException: No validator could be found for type: java.util.List<java.lang.String> at org.hibernate.validator.engine.ConstraintTree.verifyResolveWasUnique(ConstraintTree.java:236) at org.hibernate.validator.engine.ConstraintTree.findMatchingValidatorClass(ConstraintTree.java:219) at org.hibernate.validator.engine.ConstraintTree.getInitializedValidator(ConstraintTree.java:167) at org.hibernate.validator.engine.ConstraintTree.validateConstraints(ConstraintTree.java:113) at org.hibernate.validator.metadata.MetaConstraint.validateConstraint(MetaConstraint.java:121) at org.hibernate.validator.engine.ValidatorImpl.validateConstraint(ValidatorImpl.java:334) at org.hibernate.validator.engine.ValidatorImpl.validateConstraintsForRedefinedDefaultGroup(ValidatorImpl.java:278) at org.hibernate.validator.engine.ValidatorImpl.validateConstraintsForCurrentGroup(ValidatorImpl.java:260) at org.hibernate.validator.engine.ValidatorImpl.validateInContext(ValidatorImpl.java:213) at org.hibernate.validator.engine.ValidatorImpl.validate(ValidatorImpl.java:119) at com.adeuza.movalys.validation.hibernate.TestMain.main(TestMain.java:75) I don't know if it is a bug in hibernate validator. I have looked at the JSR303 and i have not seen anything about List of primitives. You can validate per example List<Person> with @Valid and it works well because the validator knows about Person class. I have used a little the Oval framework and with it, you can tell if the check applies to the container, or the values inside, or the keys(for map). I don't know if you can do that with JSR303. I'm interesting with your point of view.
