I know a lot of people are having the same problem but I'll go along and ask. I use ltng:require to import the fullcalendar js lib. Ever since the lockerservice was activated I get the following error:
Uncaught TypeError: Cannot read property 'fn' of undefined throws at /resource/fullcalendar/fullcalendar.js
I used to have the fullcalendar.min.js working alright w/o LockerService, but now I get that message. I changed from fullcalendar.min.js to fullcalendar.js as suggested in another question but does not work for me.
Does it mean that I have to wait for this library to be checked and allowed by salesforce? Any known workarounds?
