Hello,

Please take a look in the attachment image.
I want to block the user to add more than one appointments in the same task like in the example from the image.
I want to have only one appointment for the same task.
Can Awt Calendar stop the user from extend the task in more than one row ?

Hi,

You can listen to the itemModifying event of the Calendar and ensure that the moved item does not collide with another item. The following code illustrates how:

[code]calendar.addCalendarListener(new CalendarAdapter() {
     @Override
     public void itemModifying(ItemModifyConfirmEvent e) {
           if (calendar.getSchedule().getAllItems(e.getNewStartTime(), e.getNewEndTime(), e.getResource()).size() > 1)
                 e.setConfirm(false);
     }
});[/code]
Regards,
Meppy
