Block preview in page builder broken for blocks that do not belong in the default strore.

[TheBadong]

Preconditions and environment

Magento ver. 2.4.3-p2

Steps to reproduce

1. Have a magento instance with at least two stores
2. Create a cms block only visible in the store that is not the default store
3. Create a cms page in on of the two stores (doesn't matter which one)
4. Add the cms block you created, in the page through the page builder.

Expected result

Block preview should render

Actual result

No block preview is rendered

Additional information

From my research, i found that the code goes through this file vendor/magento/module-cms/Block/Widget/Block.php(131) and gets sets the default store id on the block it's trying to fetch. It then tries to look for the block from the other store with the wrong store id, and does not find it here vendor/magento/module-cms/Model/ResourceModel/Block.php(121). The block is not loaded and the preview is blank.

Note that only the preview in the page builder is broken, the page renders correctly on the frontend.

@magento I am working on this

[Dnd-Mafer]

The problem comes from the way the block is loaded:

• pagebuilder do an ajax call to https://your.magento.com/admin/pagebuilder/stage/preview/key//?isAjax=true with a payload containing the block_id (there is no store_id in it)
• in \Magento\PageBuilder\Model\Stage\Preview::startPreviewMode, it loads the block using the default store of your environnement regardless the attached website

But how to do it properly ? If your cms page is in 2 different websites and the block_id referers 2 different blocks (one on each website) : which one to display to render it in admin ?

[debuysserk]

@Dnd-Mafer rendering a block by ID should always be possible since that's a unique key. Using an identifier is different, that identifier can be used for different stores (can't overlap).

I can't reproduce this issue at the moment, although we have several other issues with previews of CMS blocks not working, this ain't one.

Update: I was wrong. Apparently one of the default storeviews was selected, I thought you referred to selecting "all store views".

[debuysserk]

How come this issue is still in the backlog? The entire multi language store view setup is borked with CMS blocks on several points.

1. the inability to select a CMS block based on an identifier instead of a block id. When you have a store independent CMS page but you insert a store specific CMS block with the pagebuilder component, that's a no go because it only saves the ID. Same with the widget through Text Component but at least you can change the block id there to a identifier through the html code view (although the html code view was enabled by us in our own module...)
2. the inability to preview CMS blocks selected by id's not on the default store view like in this case.

Content is such a big deal right now that we're having a hard time explaining our clients to just duplicate the CMS pages in this case just to make this work.

Hello,

For information, here is the response received from Adobe Commerce Core Team through Adobe Enterprise support... :

Not a Bug

because

Preview of CMS pages/blocks works only on default store view because those entities don't support the scope (there is no store view switcher like on Dynamic Blocks or Products).
