Only the default validation group is supported GWT at this time. I have no good solution for using another validation group because if you throw a validation exception from an handler, it triggers the wrong method of the Receiver<T> on the client side (onServerFailure instead of on constraint violation)

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).
