Validator is called many times

Question

I defined an validator for my inputdate. I use it in a popup window. If I get an error first time it works fine,
but if I close the popup, reopen it and get an error again my validator is called twice. if I repeat this sequence 10 times,
my validator is called 10 times and it prints the error 10 times. Since the validator method is called automatically I have no idea how to solve it.
<af:inputDate binding="#{model.guiEndDate}" label="#{bundle._END_DATE}" value="#{model.endDate}" id="id2" required="true"
validator="#{model.validateInputDate}"/>
public void validateInputDate(javax.faces.context.FacesContext facesContext, UIComponent uIComponent,
Object object) throws Exception {
Date start = (Date)getGuiStartDate().getValue();
RichInputDate inputDate = (RichInputDate)uIComponent;
Date end = (Date)object;
if (start != null && end != null && start.compareTo(end) >= 0) {
inputDate.setValid(false);
throw new Exception("start later than end date");
} else {
inputDate.setValid(true);

Hi,
Call following scripts when you are closing the popups
    function clearMsgForComponent(evt){
        AdfPage.PAGE.clearAllMessages();
        evt.cancel();
<af:commandButton text="Close">
   <af:clientListener method="clearMsgForComponent" type="click"/>
</af:commandButton>
