TimeLineView visibleRange issue

[abdulwahab247]

Hello Guys, In TimeLineView, calendar is crashing when I try to set visibleRange between {start: "2017-08-03", end: "2019-01-25"} and I have lot of events so I need them to be visible in given range of date.

Here is the code in codepen: https://codepen.io/abdulwahab4acetech/pen/GRoyBgR

Appreciate any help or fix, Thanks

Confirmed. More then 539 days can always reproduce the problem. Tracing differences between 539 and 540 with browser debugging, found following: In main.js line 57, Column 4170

  function A(l, u, i, t, r, o, f, e, c) {
    ...
  }

If 539 days, array f is filled with 2135 items. But in 540 days case, f is only filled with 51 items, causing only 18 fc-timeline-slot tags with 1st of each month generated. I can't find it in source code, so it might be a lib issue.

I believe the main issue is with slotLabelFormat; since you probably don't want a label for every day, you could remove the second line to only label the months. Also, setting slotMinWidth to 20px is not wide enough to show the month name.

Thanks for the response, I definitely do need a label for every day, and I set slotMinWidth to 20px to make the slot smaller to get the maximum view.

Here is the working screenshot without crash to get the idea:

I am using Fullcalendar v4, will this be fixed for v4 too?

It seems this all works in v5: https://codepen.io/arshaw/pen/WNrPMOV?editable=true&editors=001 Here is the same example working in v4: https://codepen.io/arshaw/pen/wvMNyqZ?editable=true&editors=001

@abdulwahab247, is a bug still present? You say things are "crashing" under certain circumstances. Can you past a link to a codepen, based off on of the links above, that demonstrates the problem?

[abdulwahab247]

It seems the bug is gone if we define the value of slotDuration property in calendar. But if we don't give the value for slotDuration the bug is still there. See this codepen example without slotDuration: https://codepen.io/abdulwahab4acetech/pen/GRoyBgR?editors=0110
