JSR 303 Wicket integration
Hi all,
I'm Ophélie @ Zenika !
As the subject states, i've got a few questions regarding the JSR 303 (bean validation) integration with wicket. That's something a lot of people at Zenika are eager to see evolving from the current "yes, it'd be great!" project to a real concrete one. I know it's part of the wicket 1.5 wishlist too, so i assume you might be interested as well ;)
To be fair, this idea came up with this blog post : http://magnus-k-karlsson.blogspot.com/2009/10/integrate-jsr-303-bean-validation-and.html
but what we really want first, is to make bean validation available as a form Behavior. Although it's still an open discussion.
As i was searching the nabble archive, i noticed that the same subject came up regularly, but i can't seem to find an ongoing project. However, i stumbled upon the wicketstuff-hibernate-behavior made by Ryan Sonnek, which is based on the Hibernate Validator framework. Unfortunately, this project has moved to the attic due to lack of updates. So i was thinking about starting over with this as a base project or inspiration, then to make it fully compatible with wicket 1.4.x and of course the JSR 303.
I know some people already did some blog posts, sharing their own code as an answer to the JSR 303 integration, but what we want here, is to make it available to a wider audience of wicket users, say, as a wicket stuff component first and, why not, as part of wicket core later on.
So, before starting anything, i need to know if someone is already taking charge of a similar project ? If not, we're ready to dig into this matter here at Zenika. So let me hear some feedback about this idea, what do you think ?
Regards.

Hi all,
As promised, here is our attempt at providing a JSR-303 (Bean
Validation) integration to Wicket. The source is for the moment stored
on GoogleCode:
http://code.google.com/p/wicket-jsr303-validators/
It comes with unit tests that cover all the situations we thought about,
and a very basic sample.
It consists of two validators which can be added either on a form
component for single field validation, or on a form as a whole to
validate all of its children components.
You can find the project announcement at our blog here:
http://blog.zenika.com
Our final goal would be to contribute the code if it is deemed worthy.
Maybe in Wicket Stuff or directly in the core if there's interest?
Please let us know what you think of it, either by mail or using the
GoogleCode issue tracker.
Cheers!

@ Rodolfo : thanks for the tip, i'll try to check this out today.
actually the name of the project is databinder-valid-hib, and you can find it on the databinder maven repo. (that's a tip for anyone having a hard time finding this project ;)
@ Igor : that's exactly what i started with, a simple validator that can be added to any TextField, that's a starter but it's not enough.
Now IMHO it would be more convenient to have something like a global form validator, just like the HibernateFormValidator of the old hibernate-validator project. Or even better, an IComponentOnBeforeRenderListener.
The idea is to only specify validation in the model objects and you're done ! I'm tired of having to repeat myself to add the exact same validation both on the server side and the client side.
So, i'll try to have something up by the end of the week (hopefully) and share it with you. Basically, i'll focus on adapting the wicketstuff hibernate-validator.
Regards.

does it need a full blown project?
BeanValidator<T> implements IValidator<T>
{
@Dependency
private transient Validator validator;
private final Class< ? > beanClass;
private final String beanProperty;
public BeanValidator(Class< ? > beanClass, String beanProperty)
{
this.beanClass = beanClass;
this.beanProperty = beanProperty;
}
public void validate(IValidatable<T> validatable)
{
Object value = validatable.getValue();
Set< ? > errors = validator.validateValue(beanClass,
beanProperty, value);
for (Object error : errors)
{
ConstraintViolation< ? > violation = (ConstraintViolation<
? >)error;
ValidationError ve = new ValidationError();
ve.setMessage(violation.getMessage());
validatable.error(ve);
}
}
}

Have you checked out databinder-validator ?
It uses Hibernate Validator, but is a great place to start
I would be interested in throwing ideas arround.
