Calendar default event editor still opening while selecting multiple cells.

1. SmartClient Version: v9.0p_2013-08-25/Enterprise Deployment (built 2013-08-25)

2. All browsers.

3. I’m using custom event editor on calendar instead of default event editor.
But default event editor opening when select multiple cells on week view and day view.

I have removed following js code fragment in the ISC_Calendar.js's 'cellMouseUp' listener for prevent open the default event editor.

JS Code:
//this.creator._showEventDialog(null, sRow, this._selectionTracker.colNum, diff);
var newEvent = {};
newEvent[this.creator.startDateField] = startDate;
newEvent[this.creator.endDateField] = endDate;
this.creator.showNewEventDialog(newEvent);


Is there any other way to prevent opening of default event editor?


Thank you in advance for your answers.
