Gerhard Petracek commented on BVAL-235:
---------------------------------------

fyi: bv payload is a subset of https://cwiki.apache.org/confluence/display/EXTVAL/Constraint+Aspects
we agreed on discussing about @ParameterKey and @ParameterValue later on.

>             Project: Bean Validation
>          Issue Type: New Feature

> 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;
> }
