Custom validators vs Hibernate validators

[mikael.brodd]

Hi,

I am trying to understand the possible combinations of different validators (to be run simoultaneously).

Adding a custom validator to my xhtml seems to make the Hibernate validator to not be run. Is that so?

Here is an example of my custom validator in xhtml:

<s:decorate id="vpnIdField" template="/view/c_edit.xhtml">
     <ui:define name="label">VPN Id</ui:define>
     <h:inputText id="vpnIdInputText"
               value="#{vpnHome.instance.vpnCounter}" 
               required="true"
               validator="vpnUniqueIdValidator"
               disabled="#{vpnAction.guiDisabled}">
           <a4j:support event="onblur"
                  action="#{vpnAction.generateTechId()}"
                  reRender="vpnIdField, vpnTechIdField" 
                  ajaxSingle="true"/>
     </h:inputText>
</s:decorate>

Now I have enabled Hibernate validation on an entity that is affected by the input field and custom validator

    @Column(name="VPN_COUNTER", nullable=true, precision=3, scale=0)
    @Range(min=1, max=99, message="VPN Id must be between 1 and 99")
    public Long getVpnCounter() {
        return this.vpnCounter;
    }

If I run this code and enter a VPN Id of 101 in the vpnIdInputText, no validation occurs. But if I remove the custom validator from the xhtml, the hibernate validator works. Is it supposed to be that way? Or have I done something wrong in order to make both validators take effect?

Did you add the EntityListener?

@Entity
@Table("USERS")
@EntityListeners({JPAValidateListener.class})

public class User {
    ...
}

No, do I have to in order to get both custom JSF validation and hibernate validation simoultaneously? Removing the custom JSF validator, the hibernate validator works perfectly.

I can't say for sure but I've used Validator pretty extensively on previous projects, always with that annotation, and never ran into that problem.  I believe it pulls Validator into the JSF lifecycle.  Verifying it is pretty simple.  Have a go at it.

Yep, that did the trick!
I'm not sure why, though. The documentation says that the JPAValidator validates the entity at insert or update. But I still get field validation and feedback in the xhtml. Strange.
But thank you anyhow :)
