this part of code was working fine till 3.3.1GA
the moment i shift to 3.3.2SR1
the calender have stopped working

then i did this in the code

<rich:calendar id="cal" datePattern="dd/MM/yyyy" showWeeksBar="false" required="true" currentDate="#{acessCalendar.selectedDate}" isDayEnabled="callmyFunc" todayControlMode="hidden"
 inputStyle="width:80px" value="#{Pojo.someDate}" ondateselected="#{action.someXDate(acessCalendar.selectedDate)}" ajaxSingle="true" requiredMessage="Please Select Date">

 <s:convertDateTime />
 <!--<f:facet name="header">
 <h:panelGrid columns="3" width="100%">
 <h:outputText value="{previousMonthControl}"
 style="font-weight:bold; text-align:left;" />
 <h:outputText value="{currentMonthControl}"
 style="font-weight:bold; text-align:center" />
 <h:outputText value="{nextMonthControl}"
 style="font-weight:bold; text-align:right" />
 </h:panelGrid>
 </f:facet> -->
 <a4j:support event="onblur" ajaxSingle="true" eventsQueue="xyz" rendered="true"> </a4j:support>
 </rich:calendar>

i basically removed the bold part from the code
now its working fine

i want to know what went wrong
weather i was using the code in worng way or due to some modification it now does not take this part of code any more

please tell me the reason so that i can modify my code accordingly
