Turns out that's exactly the way you do it. I had to make my validator class
implement Serializable. For reference, here's the code:
@Name("prefixValidator")
| @Validator
| public class PrefixValidator implements javax.faces.validator.Validator,
Serializable {
|
| @In
| EntityManager entityManager;
|
| @Transactional
| public void validate(FacesContext context, UIComponent component, Object
value)
| throws ValidatorException {
|
| entityManager.joinTransaction();
|
| String prefix = (String) value;
|
| Query q = entityManager.createQuery("from Organization o where o.prefix
= :prefix");
| q.setParameter("prefix", prefix.toUpperCase());
| if (q.getResultList().size() > 0) {
| throw new ValidatorException(makeMessage("Prefix is being used
already"));
| }
| }
|
| private FacesMessage makeMessage(String s) {
| FacesMessage message = new FacesMessage();
| message.setDetail(s);
| message.setSummary(s);
| message.setSeverity(FacesMessage.SEVERITY_ERROR);
| return message;
| }
| }
<s:decorate id="prefixDecorator" template="decorateField.xhtml">
| <ui:define name="label">Prefix</ui:define>
| <h:inputText id="prefix" size="4"
value="#{organizationEditor.instance.prefix}" required="true"
disabled="#{!organizationEditor.new}">
| <f:validator validatorId="prefixValidator"/>
| <a:support event="onblur" reRender="prefixDecorator"/>
| </h:inputText>
| </s:decorate>
