TypeError: Cannot read property 'startDate' of undefined

[Peter]

Hi

Very sometime the scheduler doesn't work after first startup. 

Then when we navigate, the scheduler stays on the same day.

We're using version 18.4.30

the error we have in the console is from the scheduler component.

this is the error msg :

TypeError: Cannot read property 'startDate' of undefined

    at Array. (chunk-vendors.c69e6b7e.js:14)

    rt @ chunk-vendors.c69e6b7e.js:14

Any idea's why this is happening ?  

We load the scheduler events data in the activated: function ()

90% of the time its ok..

Regards

Peter.

Hi

Thanks for the information.

I have found and solved my problem.

After testing in Google chrome development with slow connection setup, i could simulate the problem.

The issue was that the scheduler (with resources) , the users where sometimes loaded after the remote events.

Then i got this issue.

So i have solved it with first loading the resources in the scheduler and with an callback fucntion then the events..

Regards

Peter.
