使 Primefaces 的数据表行在行版本上无效

我正在使用 JSF 2.1 + Primefaces 5.1 开发一个网络应用程序。我有一个带有行版本的数据表，每行有 2inputText, 2 selectOneMenu and 1 selectBooleanCheckbox。我想在单击复选图标时执行一些业务逻辑验证：它将验证 2 的值selectOneMenus。为此，我创建了一个与第二个关联的自定义验证器selectOneMenu验证这两个值：

<p:dataTable id="users_table_id" var="user" value="#{usersBean.users}" rowKey="#{user.id}" paginator="true"
            paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
               rowsPerPageTemplate="5,10,15" emptyMessage="#{msgs.no_records}" sortBy="#{user.id}" sortOrder="ascending" rows="15" editable="true">
            <f:facet name="header">
                #{msgs.users}               
            </f:facet>
            <p:ajax event="rowEdit" listener="#{usersBean.onRowEdit}" update=":users_form_id:growl"/>
            <p:ajax event="rowEditInit" listener="#{usersBean.onRowEditInit}" update=":users_form_id:growl"/>
            <p:ajax event="rowEditCancel" listener="#{usersBean.onRowEditCancel}" update=":users_form_id:growl"/>
            <p:column headerText="#{msgs.id}" sortBy="#{user.id}" styleClass="centered-column">

@FacesValidator("userValidator")
public class UserValidator implements Validator {

    private static final Logger logger =  LogManager.getLogger(UserValidator.class);

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        logger.entry(context, component, value);

        if (value == null) {
            return; // Let required="true" handle.
        }

        UIInput userPlayerInComponent = (UIInput)component.getAttributes().get("userPlayerInComponent");
        if (!userPlayerInComponent.isValid()) {
            return; // Already invalidated. Don't care about it then.
        }

        DtoPlayer playerIn = (DtoPlayer)userPlayerInComponent.getValue();
        if (playerIn == null) {
            return; // Let required="true" handle.
        }

        DtoPlayer playerOut = (DtoPlayer)value;

        UsersBean usersBean = context.getApplication().evaluateExpressionGet(context, "#{usersBean}", UsersBean.class);

        BigDecimal userId = usersBean.getUserEditingId();
        logger.info(userId + " - " + playerIn.getDescription() + " - " + playerOut.getDescription());

        for (DtoUser dtoUser : usersBean.getUsers()) {
            if (!userId.equals(dtoUser.getId()) && dtoUser.getPlayerIn().equals(playerIn) && dtoUser.getPlayerOut().equals(playerOut)) {
                logger.info("Invalidating...");
                userPlayerInComponent.setValid(false);              
                FacesContext.getCurrentInstance().validationFailed();
                throw new ValidatorException(new FacesMessage("BOOM!"));
            }
        }
        logger.exit();
    }
}

我期待的是，当验证失败时（并且ValidatorException被抛出），数据表行将保持编辑模式，并且两个selectOneMenus 以红色突出显示。但发生的情况是该行退出编辑模式，保留旧值。如果我再次编辑它，它会显示提交的值，并且无效的单元格会标记为红色。只要我尝试提交无效值，这种行为就会持续下去。如果我关闭编辑模式，无效值将被丢弃，并且该行仅保留旧值（无论是在查看模式还是编辑模式下）。

我该如何解决这个问题？来自Primefaces 的展示 http://www.primefaces.org/showcase/ui/data/datatable/edit.xhtml，可以看到，当您尝试提交（比方说）年份单元格中包含字母字符的字符串时，该行将保持编辑模式并突出显示。我想实现同样的行为。
