Form Key Error with Pager on List Views

[inavdb]

Error occures in the integer_net Slider module (see also internal ticket 17261)

When in a list the number of elements exceeds the standard qty er page (here 20), you cannot edit an element when

1. You navigate to page 2 and try to open an element.
2. Switching the rows per page to e.g. 50, trying to edit en element any element

Instead, there's a form key error and you end up on the Dashboard.
Editing one of the first 20 elements, when the elements per page = 20 works though.

disproved: Note to self: it seems the form key changes when an Ajax grid update id done.

I can see the action URL is configured as <action id="edit" label="Edit" url="*/*/edit" in the grid XML.
This configuration doesn't work for Ajax updates of the grid, since they happen through a generic Ajax pager route.
Applying the following patch to the grid config should fix the issue:

diff --git a/view/adminhtml/hyva-grid/grid.xml b/view/adminhtml/hyva-grid/grid.xml

I'll leave the issue open for now until you can confirm this fixes the problem.

I've patched the UrlBuilder during Ajax requests so it will use the original route to build new URLs.
Now it will work even without a config change.
This will be part of the 1.1.16 release.

@Vinai I can confirm this working for next page navigation, but clicking previous page link won't update anything.

[Vinai]

Thanks for letting me know. I'll look into this, but it will be a while because vacation.

@lbuchholz I can't reproduce the issue paging through sliders or the test grids.
Is there any additional info you can give?

[lbuchholz]

Not really... Use case is hyva_slider with 40+ sliders, page size 20. While I can navigate to next and last page, I cannot go to previous or first page.

[Vinai]

Same behavior when you change to a page size of 10?

[lbuchholz]

Yes.

[Vinai]

I have created 30 sliders, no problem with paging back or forth.
Any errors in the console or the ajax response?

[Vinai]

Do you have an answer to my question @lbuchholz? Could you check in the network tab in the devtools if there is some kind of exception or something?

[lbuchholz]

@Vinai Sorry for taking such a long time to respond. I just did a complete reinstall of all modules involved et voilà, works. 🙄
Please close, thank you 👍
