Cannot delete the updated occurence

Scheduler Javascript
#1

Scenario:

  1. I update single occurence (successfull after refresh the page displaying correctly)
  2. After i update the single occurence and then delete it, the deletion is not success. Still displaying the updated occurence instead of removing it from the calendar.

What is the posible cause of this? Thanks

Hi,
do you set “rec_type=none” to the updated occurrence ?

yes both rec_type and rec_pattern is none and correct event_length.
But the normal event and none updated occurence are no problem when deleting.
