CKEditor nested entries are not propagated when enabling a new site (only text is copied)

[thibault-boa]

Description

When enabling a new site for an existing section in a multi-site setup, CKEditor field content is only partially propagated.

Plain text content is copied correctly, but nested entries (inserted via the "+" button / entry types) are not propagated. As a result, all embedded entries are missing on the newly enabled site, while they still exist on the primary site.

The CKEditor field itself is correctly configured (entry types available, "+" button present), and creating new nested entries on the secondary site works as expected. The issue only affects propagation of existing content when a new site is added.

Steps to reproduce

1. Create a section enabled for a primary site (e.g. en)
2. Add an entry with a CKEditor field:

• Include plain text
• Insert one or more nested entries via the "+" button

3. Save the entry
4. Add a new site (e.g. nl) with the same section
5. Let Craft propagate entries to the new site

Additional info

Craft version: 5.9.17
PHP version: 8.3
Database driver & version: mysql 8.0
Plugins & versions:
craftcms/ckeditor: 5.3.1

This is what I see when I try to paste the content with the nested entries to the new site. Seems like a similar issue like #426

Hi, thanks for reaching out! What’s the translation method of the CKEditor field in question and the propagation method for the section?

Also, your screenshot suggests that the CKEditor field is nested in a matrix field set to the blocks view mode - is that correct? What’s the matrix field’s propagation method? Are you experiencing this issue both inside and outside of a matrix block?

[thibault-boa]

Yes, the CKEditor field is being used inside a Matrix as part of a content builder setup, which contains all the page content.

Here’s the configuration:

CKEditor field

• Translation Method: Translate for each site

Matrix field

• Propagation Method: Save entries to other sites in the same site group

Section

• Propagation Method: Save entries to other sites in the same site group

I also tested this with a CKEditor field outside of a Matrix, and it shows the same behavior there as well.

Let me know if you need any additional details or if I can help test anything further.

Thanks for the extra info! I was able to reproduce the issue where nested entries weren’t getting duplicated to the new sites. It looks to be related to craftcms/cms#18621. I already raised a PR to fix it, and I tested it against this.

I’m looking into the copy and paste issue.

Quick update: I raised a PR for the copy and paste issue. Thanks again for reporting!

I saw on the Craft CMS issue you linked that the problem has been resolved. I therefore tried creating a duplicate again, and everything is working as expected. Thanks for the help!
