TYPO3 Core

I also updated the reference index and only 2 issues were found.

[WARNING] 74515 records from 78 tables were checked/updated.
Updates: 2

The error still shows up in the console.

I had the exact same issue too but i could fix it by updating the refindex.

Edit: That fixed only a few records. Not all.

I'd mark this as a regression

So this is what i found so far:

- The error is still present on 10.4.14
- Downgrading to 10.4.12 fixes the problem
- The workspace module will show some items and then abort with the above mentioned message
- Clearing the refindex (truncate the table) fixes the problem
- rebuilding the refindex with "bin/typo3 referenceindex:update" reintroduces the error

I'm still figuring out which commit of v10.4.13 introduces this.

This is indeed a regression which came with 10.4.13. Reverting the following commit clears the problem: https://github.com/TYPO3/TYPO3.CMS/commit/385b3b7ae8

I found out that this error comes situational. It appears when:
... the workspace module pagination kicks in.
... the last element in the workspace list has IRRE elements and it's elements exceed the 30 items per page threshold.

I could reproduce it like this:
1. Have a workspace and switch to it
2. create 25 text elements (i know, this is stupendous) following this pattern: "test" followed by an incrementing digit. Thats actually important as ordering is an important factor in this case
3. create a file list with 6 items as IRRE Elements
4. Go to the workspace module
5. The file list should be at the bottom of the list.
6. Go to page 2 and the error appears

I also had this error in a case that involved IRRE subitems which i don't know how to reproduce right now but it also had something to do with exceeding 30 items on the page. It got thrown right on loading the first page of the workspace module (without having to switch the pagination page) and there was a multitude of content elements containing IRRE elements with subitems.

Hi,

I successfully installed the patch with latest 10.4.14 and the console error changed to

Uncaught (in promise) TypeError: Cannot read property 'Workspaces_CollectionChildren' of null
at Backend.renderWorkspaceInfos (Backend.js?bust=1617885154:13)
at Backend.js?bust=1617885154:13

... and that means I still cannot send workspace-changes to the next stage or set it live. :-(
