Emmanuel Bernard commented on ANN-513:
--------------------------------------

Edwin,
I believe you can implement an untyped version

@GenericValidator( class=..., parameters = @Params(key=, value=) )
Then @Validators(GenericValidator[] value() )

Hibernate Annotations has the ability to "create" annotations (ie recreate the actual validator).

have a look at org.hibernate.test.annotationfactory.AnnotationFactoryTest

>          Key: ANN-513
>          URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-513
>      Project: Hibernate Annotations
>         Type: Improvement

>   Components: validator
>     Versions: 3.2.1
>     Reporter: Edwin van der Elst
>     Priority: Minor

> I have a suggestion for the following problem:
> I created an Validator to check if a 'date'> 'another date'
> The annotation looks like this:
> @After(property="endDate", after="beginDate", message="End should be after begin")
> Since it involves 2 properties, it is a class-level validation.
> Now....
> I want multiple 'after' validations on a single bean.
> But that is not possible (you can only place an annotation once on a class).
> My proposal is to add an annotation 'Validations':
> @Validations( {@After(...), @After(..)} )
> I could do the multiple validations in a single validatorclass, but I want all the messages added to the invalidValues array, not a single message.
> This change would also require changes in the ClassValidator class.
> What do you think of this proposal? Should I add it to Jira (I can propably implement it if there are no objections to the required changes)
