[Sebastian Thomschke (JIRA)]

Support parameterized payload attributes
----------------------------------------

                 Key: BVAL-235
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-235
             Project: Bean Validation
          Issue Type: New Feature
          Components: spec-general
    Affects Versions: 1.0 final
            Reporter: Sebastian Thomschke


JSR303's payload attribute values are limited to class references. 

The idea is to allow the specification of an additional String value for each payload declaration allowing more flexible configurations.

For example:

public @interface Payload {
    Class< ? > type();
    String value();
}
 
@interface MinLength {
  Payload[] payload() default {};
  // ...
}
 
class Account
{
  @MinLength(value=4, payload = {
     @Payload(type=ErrorCode.class, value="1234"),
     @Payload(type=When.class, value="groovy:this.owner != null && this.foobar > 3")
  })
  String name;
}
