Hi, Bryntum team.
Last 2 days we receiving an error 'wd.at is not a function. (In 'wd.at(-1)', 'wd.at' is undefined)'
To be honest we don't how to repro.
Have you faced with that?
Thank you
Hi there,
Sorry to hear that but It's quite hard to figure out why is it happening without proper steps of reproduction. Can you please try reverting to last stable version of your code and incrementally introduces changes to figure out what's causing it.
Also, please give this forum a read to learn what helps us identifying the issue.
