Error on drag-and-drop with FC and/or Scheduler

Hello all,

A similar error has been reported in issue #2786 but seems to be unrelated to what was happening there.

You can reproduce the bug here: https://jsfiddle.net/oehjf27a/2/

As you will see, two errors occurs. One on dragging:

Uncaught TypeError: Cannot read property 'def' of undefined
    at constructor.getEventDef (VM305 fullcalendar.min.js:10)
    at constructor.Ee.isEventInstanceGroupAllowed (VM305 fullcalendar.min.js:9)
    at function.e.constructor.isEventInstanceGroupAllowed (VM305 fullcalendar.min.js:7)
    at constructor.hitOver (VM305 fullcalendar.min.js:7)
    at constructor.trigger (VM305 fullcalendar.min.js:7)

    at constructor.startDrag (VM305 fullcalendar.min.js:6)
    at constructor.handleDistanceSurpassed (VM305 fullcalendar.min.js:7)
    at constructor.handleMove (VM305 fullcalendar.min.js:6)

and one on dropping:

Uncaught TypeError: Cannot read property 'start' of undefined
    at function.e.constructor.buildNewDateProfile (VM305 fullcalendar.min.js:10)
    at function.e.constructor.mutateSingle (VM305 fullcalendar.min.js:10)
    at VM305 fullcalendar.min.js:10

    at function.e.constructor.reportEventDrop (VM305 fullcalendar.min.js:9)
    at VM305 fullcalendar.min.js:7
    at i (VM305 fullcalendar.min.js:7)
    at constructor.stop (VM305 fullcalendar.min.js:7)
    at constructor.interactionEnd (VM305 fullcalendar.min.js:7)

Probably unrelated, but using FC 3.5.1 and scheduler 1.7.0 you have this warning which seems weird since it is the recommended version:

v1.7.0 of FullCalendar Scheduler is incompatible with v3.5.1 of the core.
Please see http://fullcalendar.io/support/ for more information.

Anyway, I’m happy to help if I can otherwise thanks for the excellent work!

@arshaw is there any plans to add recurring or repeating events to the plugin?

@MaxGuitet, scheduler v3.5.1 is actually NOT compatible with v1.7.0 of core. It needs v1.7.1.

The bug is not actually related to scheduler anyway.

The bug is happening due to your events being specified with only a time property, which is something that is done only for repeating events. In fact, repeating events are not actually support by fullcalendar officially. They are only for business-hours. When repeating events is officially implemented, I will make sure this works. Until then, it’s “unsupported” unfortunately.

Here is a jsfiddle of things working when the start/end are specified as full IEO8601 date strings: https://jsfiddle.net/oehjf27a/5/
