Exception: this.parent.activeView is undefined

[Unknown]

Hello!

I'm trying to reload events dynamically using subscription to RxJS subject but sometimes get the following exception on page load:

ERROR TypeError: "this.parent.activeView is undefined"

    getQuery ej2-schedule.es2015.js:4691
    addEvent ej2-schedule.es2015.js:4755
    addEvent ej2-schedule.es2015.js:11884

    ngAfterViewInit crews-scheduler.component.ts:80

It seems Schedule instance is not always fully instantiated inside AfterViewInit of the parent component.

Do you provide any event that I can catch and start to load scheduler events?

Here is the part of my component:

@ViewChild('scheduleObj', { static: true })

public scheduleObj: SyncfusionScheduleComponent;

ngAfterViewInit() {

        this.loadedEvents$.subscribe(events => {

// getEvents() fails sometimes here too, but this is not critical since I can skip removing if it is the first load

            if (this.scheduleObj.eventBase) {

                const existingEvents = this.scheduleObj.getEvents() as any[];

                if (existingEvents && existingEvents.length > 0)

                    this.scheduleObj.deleteEvent(existingEvents);

            }

            if (events.length > 0)

                this.scheduleObj.addEvent(events.map(clone)); // here I get the exception!

        });

    }

Hi Artem, 

 

Syncfusion Greetings. 

 

We have checked your shared scenario but scheduler working fine at our end. We suspect that your requirement is to update the scheduler event on ngAfterViewInit we have prepared the below sample for the same kindly refer it. 

 

https://stackblitz.com/edit/angular-wxxgyx-pnhwar?file=app.component.ts  

ngAfterViewInit() { 

    const studentsObservable = this.scheduleService.getSchedule(); 

    studentsObservable.subscribe((scheduleData: Schedule[]) => { 

      this.scheduleObj.eventSettings.dataSource = scheduleData; 

    }); 

  } 

 

Kindly try with the above sample and let us know if you need any further assistance on this.
