Missing event object in beforeAdd and strange effects when copy/paste Events

" Hello Bryntum!

We integrate the Scheduler Pro in our Angular-app. I think since version 6.x we encountered some problems when copy and paste events.

I describe two problems which seem related.

1. beforeAdd listener on AssignmentStore: When copying two Scheduler-Events an paste them, the second beforeAdd-event does not contain the Scheduler-Event object but the EventId. We need the object to add some properties.

Problem 1.mov

Reproduce:

• Open Demo: https://bryntum.com/products/scheduler/examples/multiassign-resourceids/
• Add AssignmentStore with beforeAdd-listener and log event.records[0].originalData.event
• Create an additional Event for 'Macy'
• Select the two Events from 'Macy' and copy
• Paste on 'Macy' => The first console entry logs the event object (as expected) => The second console entry logs the eventId (but we would expect again an object) => There are additional logs about 'Duplicate assignment of event x to resource y'

import { AssignmentStore, Scheduler, EventModel } from '../../build/scheduler.module.js?478494';
import shared from '../_shared/shared.module.js?478494';

// Making a custom EventModel to enable resourceIds field usage
class CustomEventModel extends EventModel {
    static $name  = 'CustomEventModel';
    static fields = [
        { name : 'resourceIds', persist : true }
    ];
}

//region Data

const
    resources   = 
        { id : 'r1', name : 'Celia', city : 'Barcelona' },

2. Strange effects when copy/paste Scheduler-Events Several pasting actions adds more than the desired events and suddenly pasting does not work anymore.

Problem 2.mov

Reproduce:

• Open Demo: https://bryntum.com/products/scheduler/examples/multiassign-resourceids/
• Copy (command+c) the Event of 'Macy'
• Paste (command+v) two times => The second paste adds two Events (expected only one), sometimes one of them disappears after a short moment (0.2 - 2s) => The console logs 'Duplicate assignment of event x to resource y' Select (command+c) the Event of 'Dave' Paste (command+v) => Nothing happens => The console logs 'Duplicate assignment of event x to resource y'
