SelectBooleanCheckbox in RIch:datatable

Question

Hello All,
I have data table with some actions(column 1, column 2, column 3 , delete, update)..
And selectBooleanCheckbox for checking before start delete, its must mandatory before any actions.
I added validator vor selectBooleanCheckbox to make it mandatory, but if I have 4 rows, I must select 4 checkboxes for continue actions...
But each row must have his own checkbox:)
How can I improve it...
public void validateCheckbox(FacesContext context, UIComponent component, Object value) {
    if (value instanceof Boolean && ((Boolean) value).equals(Boolean.FALSE)) {
      String clientId = component.getClientId(context);
      bundle = context.getApplication().getResourceBundle(context, "confirm");
      FacesMessage message = new FacesMessage(bundle.getString("warning"));
      throw new ValidatorException(message);
<rich:column>
                      <f:facet name="header">
                        <h:outputText value="#{regForms.action}"/>
                      </f:facet>
                      <h:panelGroup id="actions_panel">
                        <a4j:commandLink                        
                          action="#{EDIT}" value="#{edit}"
                          reRender="name_panel">
                          <a4j:actionparam name="ID" value="#{item.id}" assignTo="#{bean.editTpStatusId}"/>
                        </a4j:commandLink>
                        <a4j:commandLink                        
                          action="#{EDIT}" value="#{deletet}"
                          reRender="name_panel">
                          <a4j:actionparam name="ID" value="#{item.id}" assignTo="#{bean.deleteId}"/>
                        </a4j:commandLink>
                      </h:panelGroup>
                    </rich:column>
                    <rich:column>
                      <f:facet name="header">
                        <h:outputText value=""/>
                      </f:facet>                                            
                      <h:selectBooleanCheckbox style="border:none" id="check"  required="true" value="#{item.checked}"
                                               validator="#{bean.validateCheckbox}"/>               
                      <h:message for ="check" styleClass="validate"/>                                 
                    </rich:column>               I do not know behavior selectBooleanCheckbox in the datatable, I try to reRender checkbox after clicking in action link, but no result.

Check the "Select multiple rows" part of this article for two ways of doing it.

Although it uses h:dataTable, the idea is just the same.
