[jboss-user] [JBoss Seam] - s:validateAll PersistentClassConstraint

[marthoff]

Hello,

I have a problem when using a Hibernate Validator with PersistentClassConstraint and the s:validateAll Tag.

When accessing a property of a class which uses this validator within a JSF Page an error occurs due that the Validation Exception is not handled by the s:validateAll Tag. The exception is thrown when the entityManager tries to commit the entity.

Is there a way to validate the whole entity before commiting?

I tried to solve the problem by using a custom JSF validator but in that case it seams that I'm losing some state, because the EntityHome instance returns false for the mehod isManaged after a wrong validation.


I'm using jBoss SEAM 1.2.1.GA and code generated by "seam generate-entities".

The custom hibernate validator annotation:

  | @ValidatorClass(SerialValidator.class)
  | @Target(value = ElementType.TYPE)
  | @Retention(RetentionPolicy.RUNTIME)
  | @Documented
  | public @interface Serial {
  | 	String message() default "Wrong Serial";
  | }
  | 

The entity class:

  | @Entity
  | @Table(name = "machine")
  | @Name("machine")
  | @Serial
  | public class Machine implements java.io.Serializable
  | ...
  | 

JSF code of one property, which is checked by the validator:

  | <s:decorate id="serialDecoration" template="/layout/edit.xhtml">
  |   <ui:define name="label">#{messages.serial}</ui:define>
  |   <h:inputText id="serial" value="#{machineHome.instance.serial}" 
  |     required="true">
  |     <a:support event="onblur" reRender="machine" />
  |   </h:inputText>
  | </s:decorate>
  |
