The error appears when a exposed filter
was executed
and at the same time Ajax is active in the view

Then the 404 error appears in the Ajax request.

see my screencast

1) AJAX in the view is inactive: everything works fine
then
2) AJAX in the view is active: the changes are not saved and the error appears

I faced the Bug again
Editablefields Form action broken when Views AJAX filters are used → causes 404 on submit

Module: Editablefields
Version: 1.0.2
Drupal: 10.1+

Description
When using the Editablefields module inside a View with AJAX enabled, the action attribute of the rendered form becomes incorrect after a filter is applied.

When no filter is used, the form action is correctly set to the expected endpoint (e.g. /start), and the editable field submit works fine.

When a filter is applied, triggering an AJAX reload of the view, the form’s action is rewritten to the AJAX callback URL of the View (e.g. /views/ajax?...).
This URL is not a valid form endpoint, which results in a 404 error on submit.

Steps to Reproduce

• Create a View with a filter exposed and AJAX enabled.
• Place an editable field (via Editablefields module) into the View.
• Load the View normally → form works.
• Apply a filter → View reloads via AJAX.
• Inspect the editable form: the action attribute is now /views/ajax?....
• Try submitting the editable form → you get a 404 error.

Expected Behavior
Editablefields forms should retain the correct form action, even when a View is reloaded via AJAX.

Actual Behavior
The form's action becomes /views/ajax?..., which is not a valid endpoint for form submissions, resulting in:

AJAX HTTP error occurred.
HTTP Result Code: 404
Path: /views/ajax?...&ajax_form=1

Attempts to Fix / Workarounds Tried

• JavaScript patch: Attempted to fix the form action client-side before submission. It prevents the 404 but breaks Drupal’s built-in AJAX handling (form submit no longer works correctly).
  $('.pq-editablefields-form').attr('action', '/start');
• Manual triggering of Drupal AJAX: Using Drupal.ajax({...}).execute() also failed because the AJAX form submission logic requires correct context, tokens, and Drupal behaviors.
• Form alteration via hook_form_alter() – not triggered for Views content loaded via AJAX.
• Disabling AJAX on the View works as a fallback – but this is not an acceptable solution for use cases that depend on AJAX filters.

Root Cause Analysis
Editablefields uses the current page request to determine the action attribute. When the View is rendered via AJAX (after applying filters), the request path is the View’s AJAX callback (/views/ajax?...). This gets wrongly used as the form action, which breaks the form.

Recommended Solution (for maintainers)
Ensure the action attribute for Editablefields forms is rendered correctly, based on the entity route or a dedicated controller, not from the current AJAX request.

Possibly set the #action explicitly in the form build array using a stable URL like:
$form['#action'] = \Drupal::url('my.custom.route'); // or route to the form handler

Or determine the canonical route for the entity being edited, rather than relying on
\Drupal::request()->getRequestUri().
