[ANGULAR] Drag/Drop Error After Upgrade To 4.3.1
Posted: Tue Oct 26, 2021 11:38 am
Hi.
I work with scheduler 4.3.1v with angular 12.
After upgrade to 4.3.1 version from 4.3.0 I stated to get some error in the console:
zone-evergreen.js:172 Uncaught TypeError: Cannot read properties of undefined (reading 'event')
at EventDrag.onDrag (scheduler.lite.umd.js:152583)
at DragHelper.trigger (scheduler.lite.umd.js:46445)
at DragHelper.update (scheduler.lite.umd.js:30378)

at ZoneDelegate.invokeTask (zone-evergreen.js:390)
at Zone.runTask (zone-evergreen.js:168)
But the flow of drag/drop works fine.
After deep debug I found that the config parameter that make this error is :
constrainDragToTimeline: false
inside the eventDragFeature of the scheduler.
I create some example demo based on drag-between-schedulers.
In my case I not always have more then one scheduler.
For get this error you need to drag event on my example.
What is changed from 4.3.0 to 4.3.1 that make this error?
