Custom Validator problem.

[Ali Abdel-Aziz Ali]

Hello All,

I have Custom Validator problem.
I have two input calenders and I want to make some validation on their values
any validation.

so this the UI code:

<h:outputText value="From Date:" style="font-weight:bold"/>
<t:inputCalendar id="FromDate" monthYearRowClass="yearMonthHeader" weekRowClass="weekHeader"
                            currentDayCellClass="currentDayCell" value="#{positionPopup.fromDate}" renderAsPopup="true"
                            popupTodayString="#{example_messages['popup_today_string']}" popupWeekString="#{example_messages['popup_week_string']}"
                            renderPopupButtonAsImage="true" required="true" styleClass="required">                               
            <f:validator validatorId=" validators.datesOverlapValidator"/>
</t:inputCalendar>

<h:outputText value="Thru Date:" style="font-weight:bold" />
<t:inputCalendar id="ThruDate" monthYearRowClass="yearMonthHeader" weekRowClass="weekHeader"
                            currentDayCellClass="currentDayCell" value="#{positionPopup.thruDate}" renderAsPopup="true"
                            popupTodayString="#{example_messages['popup_today_string']}" popupWeekString="#{example_messages['popup_week_string']}"
                            renderPopupButtonAsImage="true" required="false">
</t:inputCalendar>

and this is the validator code:

public void validate(FacesContext facesContext,    UIComponent uiComponent, Object value)    throws ValidatorException
{
        if (facesContext == null) throw new NullPointerException("facesContext");
                if (uiComponent == null) throw new NullPointerException("uiComponent");
                    if (value == null)
                    {
                        return;
                    }

            UIComponent foreignComp = uiComponent.getParent().findComponent(_for);        // _for =  "ThruDate" // equall to the second inputCalender ID
            if(foreignComp==null)
                throw new FacesException("Unable to find component '" + _for + "' (calling findComponent on component '" + uiComponent.getId() + "')");
            if(false == foreignComp instanceof EditableValueHolder)
                throw new FacesException("Component '" + foreignComp.getId() + "' does not implement EditableValueHolder");
            EditableValueHolder foreignEditableValueHolder = (EditableValueHolder) foreignComp;

            if (foreignEditableValueHolder.isRequired() && foreignEditableValueHolder.getValue()== null )
            {
                return;
            }

            Object[] args = {value.toString(),(foreignEditableValueHolder.getValue()==null) ? foreignComp.getId():foreignEditableValueHolder.getValue().toString()};

            _logger.info(" From Date =  "+ args[0].toString() +" Thrue Date = "+foreignEditableValueHolder.getValue());
           
           
            boolean overlap = this.overlap ( new Range(new Date(1), new Date(2)), new Range(new Date(1), new Date(2)));
            if(!overlap)
            {
                //if(foreignEditableValueHolder.getValue()==null || !foreignEditableValueHolder.getValue().toString().equals( value.toString())  )
               
               FacesMessage message = new FacesMessage();
               message.setDetail(Messages.getMessageString("RangeOverlapValidator")+" "+ args[0].toString() +" "+args[1].toString() + ".");
               message.setSummary(Messages.getMessageString("RangeOverlapValidator")+" "+ args[0].toString() +" "+args[1].toString() + ".");
               message.setSeverity (FacesMessage.SEVERITY_ERROR);
               throw new ValidatorException(message);
            }
    }

but it always return the ThruDate = null however it can feel with it's properties like isRequired or not.

Can Any buddy help?
