TypeError : draggableviews_views_pre_render(): Argument #1 ($view) must be of type ViewExecutable, Drupal\views\ViewExecutable given

This is a strange one. I can't reproduce the cited error, and having put your suggested fix into an MR, phpcs throws an error on the declared use of ViewExecutable as unused. I also notice that the error statement referred to draggableviews_views_pre_render(), which isn't present in the draggableviews.module file in 2.1.4, and it says the error is on line 276, where the file in 2.1.4 ends on line 270. Do you have a patch applied to the 2.1.4 release?

Strange indeed! I had a former patch ( issue 3316975 🐛 Contextual Link throws RouteNotFoundException: Route "view.this" does not exist Needs review ) that I removed from my composer.json file because it seems to have been merged in the 2.1.4 release

#5 was my exact experience as well. I had the aforementioned former patch installed (3316975-15) on a client site and was experiencing the error detailed in this issue. Removing the patch, deleting the module directory, and running a new composer install remedied the error.

I am also getting the same error with 2.1.4 version of module. Attached patch fixed the issue

Thanks @gaspounet

Incidentally, composer reinstall drupal/draggableviews also achieves the same thing, i.e. deleting the directory before installing the module with patches etc.

I am going to mark this as fixed because of https://git.drupalcode.org/project/draggableviews/-/commit/d1a4a588dceae...

It adds the "Use" of viewExecutable and adds function draggableviews_views_pre_render(ViewExecutable $view) {

Oddly, I checked and did not see draggalbeviews_views_pre_render in any of the last tag versions (2.0.2->2.1.4). This makes me think everyone uses a patched version (some people hinted at it). Going from the patch version to 2.1.4 will remain broken. Going from the patched version to the next release (2.1.5, maybe) will not be an issue.

Automatically closed - issue fixed for 2 weeks with no activity.
