Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch.

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!

The todo is still there so need to be investigated if still needed and documented why.

When the parent issue was fixed, it was unclear what where the best place to deal with adding the form back on the stack.

The @todo is in submitTemporaryForm() which is a function in the base class for Views handler plugins. Here is the comment header for submitTemporaryForm():
* A submit handler that is used for storing temporary items when using
* multi-step changes, such as ajax requests.

The code in getForm() which is in ViewsFormBase.php deals with the stack of forms.

Perhaps, the first step is to identify what steps to take in the UI that trigger this functionality.

I don't think there is a bug, so the @todo could be removed. In order to make a decision, it would be an interesting to first understand how the views UI multi-step forms work, and possibly make a diagram showing the flow.

Version: 11.x-dev » main

Drupal core is now using the main branch as the primary development branch. New developments and disruptive changes should now be targeted to the main branch.
