    Can we select a day twice (one after another)

    Ray T Newbie

      Hi,

      This is what I'm trying to do: I want to display a calendar (monthly with popup=false) and the user can select a day. When the user selects a day, the background color will change do red. if he selects it again, the background color will change to red. So, it will alternate between green and red.

      I've got most of it working with the sample code from Organizer Calendar demo src code (with the dataModel). However, one isssue I'm running into is: if I select a day, I cannot reselect it immediately. However, I can select another day and come back to reselect the old one. Basically, I cannot select a day twice one after another. How do I go about doing this?

      How do I enable such that user can select and select a day?

      Here is my code:

          Sorry, I meant when the user selects, the background color will change to red. When he selects again it will turn to green.

            I do this with a CalendarDataModel which supplies a styleClass for the selected date and the following code (note the oncomplete which deselects the selected date):

             <a4j:support event="ondateselected"
             action="#{controller.toggleSelectedDate}"
             oncomplete="#{rich:component( id )}.resetSelectedDate();refreshCalendars();">
             <a4j:actionparam name="selectedDateText"
             value="#{rich:component( id )}.getSelectedDateString('#{controller.dateFormat}')"
             assignTo="#{controller.selectedDateText}"
             noEscape="true"/>
             </a4j:support>

              And refreshCalendars():

              function refreshCalendars ()
              {
               reRenderCalendar( #{rich:component( 'calendar1' )} );
               reRenderCalendar( #{rich:component( 'calendar2' )} );
              }
              


              And reRenderCalendar():
              function reRenderCalendar ( calendar )
              {
               /*
               * TODO: Get rid of this hack once the calendar.render() bug gets fixed...
               * we use the following hack because calendar.render() does not work and
               * calendar.changeCurrentDate() does nothing if month and year do not change
               */
               calendar.onUpdate();
              }
