It seems Weld proxy has the same annotations as the proxied class. However this conflicts with Bean validation spec as far as @Valid is concerned. This section of the bean validation spec is ending up in violation due to the duplicated annotation: • One must not mark a method return value for cascaded validation more than once in a line of a class hierarchy. In other words, overriding methods on sub types (be it sub classes/interfaces or interface implementations) cannot mark the return value for cascaded validation if the return value has already been marked on the overridden method of the super type or interface. "The @Valid annotation is used to declare that a cascaded validation of the given method/constructor parameters or return values is performed by the Bean Validation provider. " Here is some debug added to the apache bean validation code that shows which two classes have the @Valid on the createValidEvent method: $$$$$$$$$$$$DEBUG clazz = class org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue$Proxy$_$$_WeldSubclass method = public org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.Event org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue$Proxy$_$$_WeldSubclass.createValidEvent() $$$$$$$$$$$$DEBUG clazz = class org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue method = public org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.Event org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue.createValidEvent() $$$$$$$$$$$$$$$$$DEBUG returnValid = 2 // number of hits having @Valid If I understand correctly, I think this annotation needs to be treated differently. -- Thanks Emily ================= Emily Jiang ejiang(a)apache.org <mailto:ejiang@apache.org> _______________________________________________ weld-dev mailing list weld-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/weld-dev
