Re: Receiver method onConstraintViolation not called

Hi,
thanks for your reply.
All my session beans are stateless and i'm using  a persistence unit with jta-transaction and hibernatePersistence provider.
I didn't change the transaction attribute, so it should be 'required' by default. I also don't call transaction methods explicit.
Please correct me if i'm wrong, with request factory validation is done before the business method is invoked right?
I just did a little debugging:
validate method in serviceLayerDecorator is called.
In RelfectiveServiceLayer the validate method checks the jsr303validator ( without hibernate-validator-4.1.0.Final.jar i got log message "Unable to initialize a JSR 303 Bean Validator" when initializing).
Thought, this could be the problem, but after adding the jar the validator was initiated successful.
validate of jsr303validator (org.hibernate.validator.engine.ValidatorImpl) is called, but an empty set of constraintViolations is returned!
When this method is called on server side from the BeanValidationEventListener, the set is not empty.
For the response receiver.onTransportSuccess(text) is called on the created requestCallback in DefaultRequestTransport class.
ProcessPayload checks the constraint violatoins, but its emtpy.

See https://code.google.com/p/google-web-toolkit/wiki/RequestFactoryMovingParts#Flow for the flow on the server-side.

Notably, validation shouldn't happen in a transaction.

How are managing your sessions/transactions? What are their respective lifetimes?

Hello,
any ideas why the Receiver method onFailure is triggered instead of onConstraintViolation when validation fails on server side?
I just have to annotate the entities in my ejb module right? I'm using RequestFactory for communication with server.
On server side i'm getting a rollback exception caused by a constraintViolationException, so everything seems to be right.
I'm using JBoss 6.1.0 Final and gwt 2.4 with requestfactory(also tried gwt 2.5).
I have an extra webapplication for RequestFactory, there i have a class extending DefaultRequestTransport. On my client project i'm
doing requestFactory.initialize(eventBus, <class extending DefaultRequestTransport>.
I also did a post on gwt-validation group (https://groups.google.com/forum/#!topic/gwt-validation/skPpP2kOvaQ) with some more
information.

Thanks in advance.
