<o:validateBean>: превращает List<DemoData> в List<String>?

Я хочу использовать <o:validateBean> для проверки моего компонента на уровне класса. Боб это:

@Named
@ConversationScoped
public class ValidateClassLevelBean implements Serializable {
   ...
   @Inject
   private Conversation con;

   @Min(value = 2)
   @Max(value = 5)
   private int objectCount;

   @Valid
   private List<DemoData> listData;

   public String reInit() {
     if (!con.isTransient()) {con.end();}
     con.begin();

     listData = new ArrayList<>(objectCount);
     for (int i = 0; i < objectCount; i++) {
        listData.add(new DemoData("bbb", 3));
     }
    
    return "validProduct_2";
  }

  public String action() {
    for (DemoData d : listData) {
      logger.info("[listData: <" + d.toString() + ">]");
    }
    con.end();
    return "index";
  }
  ...
}

Фейслет выглядит так:

 <h:form id = "classLevelFormCustomCopier">
  ...
  <table>
   <ui:repeat value = "#{validateClassLevelBean.listData}" var = "data" varStatus = "loop">
    <tr>
     <td>
      <h:inputText id = "dataInput"
                   value = "#{validateClassLevelBean.listData[loop.index]}"/>
     </td>
    </tr>
   </ui:repeat>
  </table>

  <h:commandButton value = "submit" action = "#{validateClassLevelBean.action}">
   <f:ajax execute = "@form" render = "@form"/>
  </h:commandButton>

  <o:validateBean value = "#{validateClassLevelBean}"
                  validationGroups = "de.test.wholebeanvalidation.validProduct.DemoDataGroup" />

В DemoData нет ничего особенного (существует forClass-конвертер):

@ValidDemoData(groups = DemoDataGroup.class)
public class DemoData implements Serializable {
  ...
  private String strData;
  private int intData;
  
  public DemoData() {
    this.strData  = "";
    this.intData=0;
  }

  public DemoData(DemoData d) {
    this.strData =d.getStrData();
    this.intData = d.getIntData();
  }
  ...
}

Аннотация ограничения проверки:

@Constraint(validatedBy = { DemoDataValidator.class })
@Documented
@Target({ TYPE, METHOD, FIELD })
@Retention(RUNTIME)
public @interface ValidDemoData {
  String message() default "Invalid product";
  Class<?>[] groups() default {};
  Class<? extends Payload>[] payload() default {};
}

Валидатор:

public class DemoDataValidator implements ConstraintValidator<ValidDemoData, ValidateClassLevelBean> {
  ...
  @Override
  public void initialize(ValidDemoData constraintAnnotation) {
    logger.info("[ init ]");
  }

  @Override
  public boolean isValid(ValidateClassLevelBean value, ConstraintValidatorContext context) {
     ...
     return true;
  }
}

Удалил copier = "..." и появилось исключение:
