I am using rich calendar on page with popup equals false.

<rich:calendar value="#{holidayHome.instance.date}" 
            popup="false" showApplyButton="false"  mode="Client" preloadRangeBegin="#{calendarDataModel.beginDate}" preloadRangeEnd="#{calendarDataModel.endDate}" 
            cellWidth="100px" cellHeight="100px" showWeekDaysBar="true" showHeader="true" 
            boundaryDatesMode="none" showWeeksBar="true"
            onchanged="{ajaxSubmit();}" oncurrentdateselect="return true" dataModel="#{calendarDataModel}"  valueChangeListener="#{calendarDataModel.valueChanged}" id="organizer" showFooter="true">
            <a:outputPanel layout="block" id="cell" style="height:50%;">
<h:panelGrid columns="1">
                    <h:outputText value="{day}"/>
                    <h:outputText value="{data.shortDescription.escapeHTML()}"/>
                    <h:outputText value="{data.description.escapeHTML()}"/>
                </h:panelGrid>
            </a:outputPanel> </rich:calendar>

I see that getData method is responsible for getting the data of each day, getData takes array of date  for which it has to get the data(For UI to display).
I want the data for entire year, so ideally the getData method should be evoked with entire year array, but this is not happening, I see that whenever the calendar is loaded getData is evoked with only the current month date array. I dont know from where getData method is getting called.
I used preloadRangeBeggin and preloadRangeEnd but didnt helped.

Any idea abt this component ?
