Problem in Recurring Event(dhtmlx scheduler)

In The Given sample for Recurring event -sample_recurring.html file you have commented

/var dp = new dataProcessor(“events_rec”);
dp.init(scheduler);
/

can anyone tell me why?

Which sample you are referring to?
DataProcessor can be used with recurring events, same as for normal ones, so, most probably, in the related sample this part of code was disabled just for demo purposes
