Af:query validation?

Question

Hello,
I want to handle client side validation for one of the query criteria rendered inside af:query component , checking that operator can not null
but there is no such thing as validator on af:query component
No , such method addValidator/ setValidator to add custom validator
Is there any way to do this or its not possible?
thank you

not a big fan of doing following everytime..., but it works
so, I have one commandButton, performing some action and I want to validate filter operators for not null
RichQuery is associated with backing bean
unfortunately, you will get hold of the components once the af:Query is Fully Rendered , which is what happening in this case
    public void checkForValidation(ActionEvent event){
        List<UIComponent> richQueryComponents = richQuery.getChildren();
        RichPanelGroupLayout richQueryPanelGroupLayout = (RichPanelGroupLayout) richQueryComponents.get(0);
        List<UIComponent>  richQueryPanelGroupLayoutComps = richQueryPanelGroupLayout.getChildren();
        for(int i=1;i<richQueryPanelGroupLayoutComps.size();i++) {
                 Application application = FacesContext.getCurrentInstance().getApplication();
                 RichPanelLabelAndMessage panelLabelAndMessage = (RichPanelLabelAndMessage) richQueryPanelGroupLayoutComps.get(i);
                 RichSelectOneChoice operSelectOneChoice = (RichSelectOneChoice) panelLabelAndMessage.getChildren().get(1);
                 operSelectOneChoice.setAutoSubmit(true);
                 application.addValidator("OperatorValidator","com.simplyadf.OperatorValidator");
                 Validator validator = application.createValidator("OperatorValidator");
                 MethodBinding methodBindingExpression= FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{pageFlowScope.myBackingBean.filterOperValueChanged}",new Class[]{ValueChangeEvent.class});
                 operSelectOneChoice.setValueChangeListener(methodBindingExpression);
                 operSelectOneChoice.addValidator(validator);
                 operSelectOneChoice.validate(FacesContext.getCurrentInstance());
