Define how method constraints are declared at parameters and return values -------------------------------------------------------------------------- Key: BVAL-245 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-245 Project: Bean Validation Issue Type: Sub-task Components: spec-general Reporter: Gunnar Morling Fix For: 1.1 Emmanuel: {quote} Constraints on parameters whose type is a subtype of the accepted types by the constraint are declared directly on the parameter void doHarm(@NotEmpty String kittenName); Constrains on parameters whose type is a constrained bean needs an annotation accepting the targeted groups. It was proposed to use @Valid for such case but [recent discussions|https://hibernate.onjira.com/browse/BVAL-208?focusedCommentId...] brought that back on the drawing board. There are a few notions floating around @Valid 1. cascade validation to nested beans 2. translate the validation of group A from the owning bean to validation of the group B on the nested bean (see BVAL-208) 3. define the group to validate in a method level validation About 3., I wonder if this should be part of Bean Validation or be part of the interception framework. In other words: * should it be an annotation provided / proposed by Bean Validation and recognized by interception techs like CDI, @Inject, Spring, AspectJ etc * should each interception tech provide its own annotation to specify the targeted group(s) {quote} -- This message is automatically generated by JIRA.
