Bryntum Support Forums

We are using Bryntum Grid as part of a Salesforce LWC solution. It seems to work well on Chrome but when we use it in Firefox, we frequently (but randomly) get the message:
Sorry to interrupt
This page has an error. You might just need to refresh it. First, would you give us more details? (We're reporting this as error ID: -635202684)
Technical Stuff
[headerText is null]
resizeToFitContent()@https://massive.lightning.force.com/resource/1717747350000/bryntumBundle/schedulepro.lwc.module.js:82025...
See attachment.

Note: the error ID does change.

Possibly related (and easier to reproduce), when we open a modal dialogue box and focus in a cell and then click anywhere outside the dialogue box we get an error with "Technical Stuff":
[commonAncestorEl.dispatchEvent is not a function]
focusin()@https://massive.lightning.force.com/resource/1620996414000/bryntumBundle/schedulerpro.lwc.module.js28
focusout()@https://massive.lightning.force.com/resource/1620996414000/bryntumBundle/schedulerpro.lwc.module.js23
handler()@https://massive.lightning.force.com/resource/1620996414000/bryntumBundle/schedulerpro.lwc.module.js76

I'm using:

• Firefox 88.0.1 (64-bit)
• MacOS Big Sur v11.2.2
• Bryntum Scheduler Pro 4.0.8

Hello.
Can you please try recently released version 4.1.3 first? To see if issue is still reproducible.
When you try it, please note breaking changes between releases. Most notable - init method no longer required.

Hi there, try using the latest version of firefox.
It will definitely solve your problem.
Hope it helps.
