<af:selectBooleanCheckbox id="sbc2"
                                              value="#{row.bindings.accountingofficer.inputValue}"
                                              required="true"
                                              autoSubmit="true"
                                              showRequired="true"
                                              label="Accounting Officer"/>
is doing validation at the moment,even if i did this required="true"

Answer 1

Such a case can be handled when u fire a ValueChangeListener which validates it every time a checkbox is selected or unselected. The method needs to validate against all the records hold up in the iterator or against the DB as required by the usecase.
