Hi, When I create a recurrent task, and then delete an occurrence (let's say, the first one, because the task is done), this occurrence becomes an "exception" in the task's "Recurrence" view. But, the start- and due-date doesn't change in the todolist, which could be seen as inconsistent. This leads at least to two problems: - in the todolist, the tasks appears with red background (as for all old undone tasks), as a reminder. That could be acceptable, but still more annoying: - in the agendaview, the "undone" task's occurrence is listed among current day's tasks, even if in fact, that occurrence was marked as exception by deleting it. Hence, I think that when handling recurrent tasks, korganizer should internally define a start- and due-date which takes in count the existence of exceptions. Regards STEPS TO REPRODUCE 1. Define a recurrent task 2. Delete the first occurrence OBSERVED RESULT Todolist still show the former start- and due-date and agendaview shows the task as undone. EXPECTED RESULT Todolist and Agendaview act as if the start- and due-date changed.
