custom fields to lightbox not showing correct db values

i have added some custom fields to lightbox, like combobox checkbox

when i create rec event and change single instance by providing other values and save it, next time when i open same single instance for edit it shows values of rec event and not the values which i changed for that instance.

example :

rec event for every week (4 weeks in month)
changed the event description some values of 1st week instance and saved it
again opened that single instance for edit
shows event values not the edited values

Most probably the problematic behavior is not related to the custom editor. Please be sure that

  • there is no js errors during data saving
  • you have both time and recurring sections, and time section is below of recurring one
  • server side responds with correct status

After modification the instance of recurring event, it must have a separate record in DB, is it created?
