The event is blockable and can be used for validation. Return false to cancel the default processing.

Please, note:

  • When the event fires - values set in the lightbox haven't beed applied to the original event yet and scheduler.getEvent(id) will return you an unmodified instance.
  • The 'ev' object will contain just values that are set by the lightbox, i.e. if the lightbox has just 1 input - the 'ev' object will have only 1 property defined
