I've setup a Kendo Scheduler widget using Kendo Web GPL version 2013.3.1119.
It's mostly working fine, in that events are pulled from the remote SchedulerDataSource and correctly displayed on the calendar with their associated resource.
The problem is ... when I double-click an event the popup editor is displayed containing the correct data, but if I click Cancel or the close 'X', the event is removed from the calendar.
There are no errors, the event just disappears.
Any ideas what may be causing this?
