Hi all,
I'm writing Custom Validators (server side I mean) in order to validate an entity before a persist() call (and only in this specific case). Actually my final goal is to display localized messages when users want to insert a duplicate entry in my CRUD Webapp. To do this, i have tried to play with validation groups and validation triggers. In Hibernate you can associate Custom ValidationGroup (Here com.test.cis.server.validator.PreRemove , com.test.cis.server.validator.PrePersist, com.test.cis.server.validator .PreUpdate) and validation triggers. * * *persistence.xml* <property name="javax.persistence.validation.group.pre-remove" value=" com.test.cis.server.validator.PreRemove"/> <property name="javax.persistence.validation.group.pre-persist" value= "javax.validation.groups.Default,com.test.cis.server.validator.PrePersist"/> <property name="javax.persistence.validation.group.pre-update" value= "javax.validation.groups.Default,com.test.cis.server.validator.PreUpdate"/> On my bean, I've put my custom annotation with com.test.cis.server.validator.PrePersist.class as validation group. @MyConstraint(groups=com.test.cis.server.validator.PrePersist.class) So my problem turns around the GWT validation with requestfactory : the validation is done *before* (so the validation will not execute my custom validator at this time ) the call to persist (which will trigger myConstraint validator) so GWT can't handle Constraint Violation exception that occurs during a method call(i.e during method execution). In this case, the exception is catch by the standard ExceptionHandling mechanism and every informations / Localized messages are lost. javax.validation.ConstraintViolationException: validation failed for classes [com.test.domain.entity.CatalogueEntity] during persist time for groups [javax.validation.groups.Default, com.test.cis.server.validator.PrePersist, ] Have you ever been in this case ?
