Breaking: #82426 - ExtJS and ExtDirect removal

See Issue #82426

Description

ExtJS and ExtDirect support has been removed from the core (TYPO3 Backend). ExtJS Javascript is not loaded now in TYPO3 Backend. ExtDirect classes were removed without substitution.

Removed classes:

  • TYPO3\CMS\Backend\Tree\ExtDirectNode
  • TYPO3\CMS\Backend\Tree\Pagetree\Commands
  • TYPO3\CMS\Backend\Tree\Pagetree\DataProvider
  • TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeCommands
  • TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeDataProvider
  • TYPO3\CMS\Backend\Tree\Renderer\ExtJsJsonTreeRenderer
  • TYPO3\CMS\Backend\Tree\Pagetree\PagetreeNode
  • TYPO3\CMS\Backend\Tree\Pagetree\PagetreeNodeCollection
  • TYPO3\CMS\Core\ExtDirect\ExtDirectApi
  • TYPO3\CMS\Core\ExtDirect\ExtDirectRouter
  • TYPO3\CMS\Workspaces\Hooks\PagetreeCollectionsProcessor

Removed methods:

  • TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeDataProvider->getNodeTypes()
  • TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeDataProvider->loadResources()
  • TYPO3\CMS\Core\Page\PageRenderer->setExtJsPath()
  • TYPO3\CMS\Core\Page\PageRenderer->getExtJsPath()
  • TYPO3\CMS\Core\Page\PageRenderer->addExtOnReadyCode()
  • TYPO3\CMS\Core\Page\PageRenderer->addExtDirectCode()
  • TYPO3\CMS\Core\Page\PageRenderer->loadExtJS()
  • TYPO3\CMS\Core\Page\PageRenderer->enableExtJsDebug()

Removed interfaces:

  • TYPO3\CMS\Backend\Tree\Pagetree\CollectionProcessorInterface
  • TYPO3\CMS\Backend\Tree\EditableNodeLabelInterface
  • TYPO3\CMS\Backend\Tree\DraggableAndDropableNodeInterface

Impact

JS code relying on ExtJS will stop working. PHP code relying on ExtDirect classes being available will now throw a fatal error.

Affected Installations

All installations having extensions relying on ExtJS being loaded or using ExtDirect API.

Migration

JS code relying on ExtJS has to be reworked to not use ExtJS or to load ExtJS from custom extension. PHP code related to ExtDirect should be changed to regular Backend AJAX routing.
