Form state errors break nested layout paragraphs dialog

Has anyone encountered the same problem ?

I've ran into some oddities with the module, I think this was one of them.

I have the same problem.

After investigating a little, I noticed that when the validation messages for the mandatory fields of the form are shown, all open dialogs (level 1 and level 2) are replaced with the form that gave an error, which means that all open dialogs have the same content.

It seems to me that this problem is happening due to some problem updating the dialogs/forms with AJAX.
However, I was unable to identify the origin of this problem.

I'm having the same issue with nested paragraphs.

For example our paragraphs are filled with the content below:

1. Text
2. Media
3. Collapse (content with paragraphs)
1. Text
2. Media

Steps to reproduce:

1. Edit collapse
2. Opens first dialog with layout paragraphs
3. Edit text inside the collapse
4. Opens second dialog on top of the first one with the text editor
5. Try to submit without a body (body is required)
6. Will show a validation error after Drupal updates the modals via Ajax
7. Result: Modal 1 and Modal 2 contains the form of the nested text paragraph with the validation error
8. After submitting Modal 2 with the required body, it can not reference to modal 1 since this modal/form is also replaced with the form with validation errors

@erwinvb For media entities, use the patch from https://www.drupal.org/project/drupal/issues/3345064 🐛 Media library field_widget_id is not unique enough Needs work

Hit this issue too when creating a tabbed content component in D10.2 with Layout paragraphs 2.04.

Currently experiencing the same issue on Drupal 10.2.4 and layout_paragraphs 2.0.4

Here is a patch with a fix.

As @erwinvb mentioned, the problem is that nested dialogs have the same data-drupal-selector attribute. Current patch adds also paragraph bundle to the attribute, to make it more unique. It will probably work for most cases, except when for some reason we have the same paragraph form opened in nested dialogs. This case will require each dialog to know how deep in the nesting level it is.

Current patch is a quick fix for the most people :)

Just ran into the same issue. I agree this is major and still existing in latest release.
