[hibernate-issues] [Hibernate-JIRA] Issue Comment Edited: (BVAL-202) Apply constraints on the elements of an iterator

[ http://opensource.atlassian.com/projects/hibernate/browse/BVAL-202?page=c... ] Emmanuel Bernard edited comment on BVAL-202 at 3/15/10 10:41 AM: ----------------------------------------------------------------- Use a specific group as a marker to define that a constraint should be applied on the elements {code} @NotNull @Size(max=30) @Size(max=50, groups=OnElements.class) @Email(groups=OnElements.class) Collection<String> emails;{code} @NotNull and @Size(30) are applied on the collection and @Size(50) and @Email are applied on the elements of the collection This solution reads extremely well but is kind of a hack of groups as this special group does not convey the semantic of groups. An alternative approach is to use Payloads {code} @NotNull @Size(max=30) @Size(max=50, payload=OnElements.class) @Email(payload=OnElements.class) Collection<String> emails;{code} but I am reluctant to use payload for some core behaviors of Bean Validation was (Author: emmanuel): Use a specific group as a marker to define that a constraint should be applied on the elements @NotNull @Size(max=30) @Size(max=50, groups=OnElements.class) @Email(groups=OnElements.class) Collection<String> emails; @NotNull and @Size(30) are applied on the collection and @Size(50) and @Email are applied on the elements of the collection This solution reads extremely well but is kind of a hack of groups as this special group does not convey the semantic of groups.
