This is a Next.js template to use when reporting a bug in the Next.js repository with the app/ directory.

What's the problem?

Only in dev mode Lexical registerUpdateListener with Next.js 14.2.0 works differently than with Next.js 14.1.1.

In production mode, both versions work as expected.

To reproduce, run the project and open the console. You will see:

binding counter 0
binding counter 1
Update listener from instance 0

Typing in the editor triggers updates from instance 0.

If you run

npm i [email protected]

And run the project again, you will see:

binding counter 0
binding counter 1
Update listener from instance 1

Typing in the editor triggers updates from instance 1.
