Breaking: #79227 - Removed ExtDirect State Provider

See Issue #79227

Description

The ExtDirect based State Provider for ExtJS applications (endpoint TYPO3.ExtDirectStateProvider.ExtDirect) has been removed.

The ExtDirect endpoint TYPO3.ExtDirectStateProvider.ExtDirect is no longer available.

The following PHP classes have been removed: * \TYPO3\CMS\Backend\InterfaceState\ExtDirect\DataProvider * \TYPO3\CMS\Backend\Tree\AbstractTreeStateProvider * \TYPO3\CMS\Backend\Tree\AbstractExtJsTree

The relevant JavaScript file ExtDirect.StateProvider.js has been removed.

The PHP method php:DocumentTemplate->setExtDirectStateProvider() to load the JavaScript file has been removed.

Instead the jQuery-based AMD module TYPO3\CMS\Backend\Storage is incorporated to load the data the same way via an anonymous State Provider which is handed to ExtJS as long as ExtJS is still available in the TYPO3 Core.

Impact

Accessing the ExtDirect endpoint will result in a JavaScript error. Loading the JavaScript file will result in a HTTP 404 error.

Instantiating the PHP class will result in a fatal PHP error.

Affected Installations

Any installation using custom implementations with ExtDirect and the State Provider shipped with the TYPO3 Core.

Migration

Include the TYPO3\CMS\Backend\Storage, and use the UserSettingsController class directly on the PHP side to access the user settings.

See the implementation of the JavaScript Storage object for a more detailed usage.
