Deprecation: #84337 - Protected methods and properties in ListController

See Issue #84337

Description

This file is about third party usage (consumer that call the class as well as signals or hooks depending on it) of TYPO3\CMS\Backend\Controller\Wizard\ListController.

A series of class properties has been set to protected. They will throw deprecation warnings if called public from outside:

  • [not scanned] pid
  • [not scanned] P
  • [not scanned] table
  • [not scanned] id

All methods not used as entry points by TYPO3\CMS\Backend\Http\RouteDispatcher will be removed or set to protected in v10 and throw deprecation warnings if used from a third party:

  • [not scanned] main()

Impact

Calling above method on an instance of ListController will throw a deprecation warning in v9 and a PHP fatal in v10.

Affected Installations

The extension scanner will find all usages, but may also find some false positives. In general all extensions that set properties or call methods except mainAction() are affected.

Migration

In general, extensions should not instantiate and re-use controllers of the core. Existing usages should be rewritten to be free of calls like these.
