Uncaught TypeError: n.$server.setRequestedRange is not a function

Flow

Just noticed this; When scrolling in a grid it didn’t fetch the next batch of rows. Instead I got this in the browser log:

We recently upgraded Vaadin 24.8.4 → 24.9.4
Note: Even though this is in dev, we are always using prod.bundle
As far as I can tell, prod.bundle was generated and checked in as part of the upgrade, and I see no version mismatch warnings anywhere.

I see there is a 24.9.5 now, but I don’t see anything that sounds like a fix for this.

Hello! It sounds like the prod bundle still includes an old version of gridConnector, which calls $server.setRequestedRange when it should be calling $server.setViewportRange. Could you please double check if the bundle was properly regenerated after the upgrade?

3

Looks like the problem was src\main\frontend\generated
For some reason that was not under version control.
I guess I assumed it was just used to produce the bundle?

I deleted this dir, did a build which recreated it but did not touch the bundle.
After that it worked fine.
I guess I have to check in generated as well

4

frontend/generated is supposed to re-generated as necessary rather than being in version control. There might be some bug hiding somewhere that prevented that from working but hard to tell without digging further…

5

Well, imho, if it is in src it should be checked in.
Btw, the reason I didn’t see it was because I had a wildcarded gitignore from when frontend was outside src

6

We would love to have it outside src/ for that reason but it basically needs to be adjacent to regular src/main/frontend/ content for the integration to work well in practice.
