The required field setting for all media type fields is also omitted.

@Fedik didnt we see this before?

Need more info, it is not very clear what exactly going on.

How did you create subfrom field, with XML in your extension or it is Joomla Custom field?
What parameters the field have?

This has been happening since the update to 5.4.0. I've tried uploading an image and diagram to visualize the problem, but it doesn't work.

Steps to recreate the problem:

• Create a new field group:

• Create three Joomla fields for the group: 1st text, 2nd media, 3rd media, indicating that they are for subforms and that they are all required (this is optional).

• Create a subform field for the same group and include the three previous fields (it doesn't matter if it's repeatable or not).

• Try populating the group by selecting files for the two media fields.

Result: Only the first media field (select) is updated, even though 20 different fields are created and selected. The required field setting also doesn't work.

All fields are from the Joomla core, and this is on a clean installation from version 6 beta. The same thing happens with Joomla 5.4.

This could be a JavaScript error. The console displays the following error as soon as one of the fields receives focus (Three resources are being displayed because the group form has three media fields):

Duplicate form field id in the same form. Multiple form field elements in the same form have the same id attribute value. This might prevent the browser from correctly autofilling the form.

To fix this issue, use unique id attribute values ​​for each form field.

Unfortunately I cannot reproduce the error. It is working good for me.
I made subform Custom field with 2 media in it and each time I add a new subform row and add value to the media fields all is working good.

As a guess, please check whether you have override for layout joomla.form.field.media from older version.
Also could be that there are some other extension involved here and break the field.

Thank you for your reply. This is happening on more than 30 websites, primarily using Yootheme/Essentials and Akeeba. I don't have many other dependencies on extensions, and I haven't overridden any settings in that regard.

I'm wondering what could be interfering in the backend content manager (fields and field groups), because the duplicate IDs of the elements are clearly visible in the DOM, and they're out of order and don't correspond to the container name/label.

I'm going to perform a completely clean test installation from scratch and will provide a detailed report. Thank you very much.
