Calendar and validation

[pawelduda]

Hi,

I am trying to validate a calendar on picking a new date by attaching a <f:validator> to it. This works fine unless the user presses the "clean" button.. When this happens, the validator doesn't launch (probably no event sent).

I was trying attaching <a4j:support> with various events from DevGuide but the closest I got was launching the validator but with old value (instead of expected null).

How to perform a validation for a calendar on the date pick/clean? I'm not interested in setting "required=true" since this will later be a form validation. And this should work without additional buttons - on date pick/clean event.

Thanks!

Here's the code I am using:

<rich:calendar
 id="taskStartDate"
 popup="true"
 value="#{taskViewBean.filterStartDate}"
 datePattern="#{sessionBean.calendarPattern}"
 boundaryDatesMode="active"
 showApplyButton="true">
 <h:outputText value="{day}">
 </h:outputText>
 <f:validator validatorId="datumValidator"/>
 <a4j:support event="onchanged"/>
</rich:calendar>

using slightly modified richfaces-demo sample

 <rich:messages></rich:messages>
 <rich:calendar value="#{calendarBean.selectedDate}"
 locale="#{calendarBean.locale}"
 popup="#{calendarBean.popup}"
 datePattern="#{calendarBean.pattern}"
 showApplyButton="#{calendarBean.showApply}" cellWidth="24px" cellHeight="22px" style="width:200px"
 required="true">
 <a4j:support event="onchanged"/>
 </rich:calendar>

I'm getting messages appears just after I clicking clean. 3.3.1 snapshot.
