isSlotAvailable returns false from within scheduleObject.saveEvent()

[Stefan]

Hi,

when I check if the slot is available in onActionBegin for an existing event from the editor, isSlotAvailable() returns true.

If I programmatically change the event and call saveEvent(data), the same function with the same parameters returns false in onActionBegin:

console.log(data.StartTime, typeof(data.StartTime), data.EndTime, groupIndex, typeof(groupIndex),

                getScheduleObject().isSlotAvailable(data.StartTime, data.EndTime, groupIndex));

Through the Editor:

Wed Mar 20 2019 08:00:00 GMT+0000 (Greenwich Mean Time), Wed Mar 20 2019 10:00:00 GMT+0000 (Greenwich Mean Time), 1, true

Through saveEvent()

Wed Mar 20 2019 08:00:00 GMT+0000 (Greenwich Mean Time), Wed Mar 20 2019 10:00:00 GMT+0000 (Greenwich Mean Time), 1, false

e.g.

getScheduleObject().getEvents()[0].Subject = "Some Changed Subject here" // << (Event exists!)

getScheduleObject().saveEvent(getScheduleObject().getEvents()[0])

Editing the same event through the editor (making the same change, e.g .to the Subject), works fine.

Could you please point me towards my error?

Thanks!

It's the same whether accessing ..getEvents[index] or ..eventsData[index].

What is funny is that the Guid appears to change on the event. From Editor:

EndTime: Wed Mar 20 2019 10:00:00 GMT+0000 (Greenwich Mean Time) {}

EndTimezone: null

Guid: "19cc52ba-7c1a-b5d4-7b55-00aadafaa366"

Id: 2094

IsBlockAppointment: false

IsReadOnly: false

From saveEvent()

EndTime: Wed Mar 20 2019 10:00:00 GMT+0000 (Greenwich Mean Time) {}

Guid: "ba6faeb8-a22b-9fad-796e-8a96ca7bb37a"

Id: 2094

IsBlockAppointment: false

IsReadOnly: false

Guid is different, Start and EndTimeZone is null from Editor, but not there at all from saveChanges().  RecurrenceRule: null from saveChanges(), but undefined from Editor. This is slightly weird...

[Stefan]

After looking through the code, I could see that isSlotAvailable compares the guid to Schedule.activeEventData.event.

So in theory this should work until the bug is fixed:

let eventToModify = getScheduleObject().getEvents()[0];

eventToModify.Subject = "Some Changed Subject here"

getScheduleObject().activeEventData.event = eventToModify;

getScheduleObject().saveEvent(eventToModify);

Will I have to combat any side effects if I go down this path? Can I leave the "element" as undefined, or as whatever it is at that time?
