TYPO3 Core

Preconditions:¶

• Any TYPO3 v11 (or later) installation
• PHP 8.x
• Workspaces extension enabled
• no further extensions or configuration required

How to reproduce:¶

• Create a Workspace
• Create a page
• Add two content elements (in LIVE mode)
• Switch to the workspace
• Drag & drop the first element after the second element - page will be marked as "modified" in the page tree
• Try to add a new content element between or after these elements

You get this exception:

PHP Warning: Undefined array key "pid" in /app/packages/typo3/typo3/sysext/backend/Classes/Utility/BackendUtility.php line 3445

Background¶

This bug was introduced with https://review.typo3.org/c/Packages/TYPO3.CMS/+/65797

A potential workaround is to add the "pid" field to the list of `BackendUtilities::getCommonSelectFields` (see attached patch, which we will deploy in production to our customer to get around the problem for now). But maybe this is just hiding the real "problem". The @todos in `BackendUtilities::workspaceOL` give me a vibe that something could be fishy around here.
