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
