Cannot read property 'isTimelineView' of undefined

[Jan van Rossum]

After placing a new fresh default schedule in our Angular application we are getting the following error in the (Chrome) JS console:

core.js:9110 ERROR TypeError: Cannot read property 'isTimelineView' of undefined

    at ComponentBase.<anonymous> (ej2-schedule.es2015.js:11023)

The scheduler is rendering fine, everything else is working as expected.

We are using the TimelineWeek view.

Do you have any idea how we can prevent this error? Thanks in advance.

Hi Jan, 

 

Syncfusion greetings. 

 

We have checked the reported case in the below sample and no script error occurs.  

https://stackblitz.com/edit/angular-3uyt59?file=app.component.html 

 

Kindly try the sample and if the issue persists, try to reproduce the error in a sample and revert else share your code example/runnable sample (if possible) to serve you better. 

 

Regards, 

Karthi

Thanks for the example.
It helped me fix this bug.

It seems like it had something to do with the timing of the selectedDate binding in my implementation.

What helped me on the right track is seeing your example where the selectedDate binding is two way => [(selectedDate)]

Most welcome 😊
