Deprecation: #90856 - Widget AutoComplete ViewHelper

See Issue #90856

Description

The Fluid ViewHelper <f:widget.autocomplete> and the related controller TYPO3\CMS\Fluid\ViewHelpers\Widget\Controller\AutocompleteController have been marked as deprecated and will be removed in TYPO3 v11.

The widget depends on third-party libraries that cannot be maintained for a full LTS release lifecycle.

Impact

Any usage of this ViewHelper or extending one of the following classes will trigger a PHP E_USER_DEPRECATED error:

  • TYPO3\CMS\Fluid\ViewHelpers\Widget\AutocompleteViewHelper
  • TYPO3\CMS\Fluid\ViewHelpers\Widget\Controller\AutocompleteController

Affected Installations

Any TYPO3 installation with custom templates that contain this ViewHelper.

Migration

Remove any usages within the Fluid templates. There is no replacement provided by the core. If you need this widget, you have to provide your own implementation with your own frontend libraries for the handling.

If you still need it, copy the ViewHelper and Controller into an own extension.
