[hibernate-dev] [HV] Ability to apply constraint on elements of an Iterable instance

Hi there, Emmanuel and I had a discussion regarding a use case given in http://opensource.atlassian.com/projects/hibernate/browse/HV-264 What if you have a list of strings and want to make sure that each string is a valid email. Something like this (@Valid is not helping here either): @Email List<String> emails ; Initially I thought the problem could be quite easily solved by a custom ConstraintValidator<Email, Iterable<String>>, but as it turns out there are issues with generating the right property path for invalid emails using the current ConstraintValidatorContext API. Besides a custom ConstraintValidator would only be a specific solution for a general problem. Hence, Emmanuel and I discussed some solutions and summarized them on http://opensource.atlassian.com/projects/hibernate/browse/BVAL-202 and http://opensource.atlassian.com/projects/hibernate/browse/HV-296 It would be great to get some feedback. --Hardy
