Deprecation: #101559 - Extbase uses ext:core ViewInterface

See 101559

Description

The default view of ext:extbase now returns a view that implements
\TYPO3\CMS\Core\View\ViewInterface and not only
\TYPO3Fluid\Fluid\View\ViewInterface anymore. This allows implementing
any view that implements \TYPO3\CMS\Core\View\ViewInterface, and frees
the direct dependency to Fluid.

The default return object is an instance of
\TYPO3\CMS\Fluid\View\FluidViewAdapter which implements all special
methods tailored for Fluid. Extbase controllers should check for
instance of this object before calling these methods, especially:

• getRenderingContext()
• setRenderingContext()
• renderSection()
• renderPartial()

Method calls not being part of \TYPO3\CMS\Core\View\ViewInterface or
the above listed method names have been marked as deprecated and will be
removed in TYPO3 v14.

Impact

Extbase controllers that extend
\TYPO3\CMS\Extbase\Mvc\Controller\ActionController and call methods
not part of \TYPO3\CMS\Core\View\ViewInterface, should test for
$view instanceof FluidViewAdapter before calling
getRenderingContext(), setRenderingContext(),
php:renderSection() and
renderPartial().

All other Fluid related methods called on $view have been marked as
deprecated and will log a deprecation level error message.

Affected installations

Instances with Extbase based extensions that call $view methods
without testing for \TYPO3\CMS\Fluid\View\FluidViewAdapter.

Migration

Methods on "old" Fluid instances were wrapper methods for
\TYPO3\CMS\Fluid\Core\Rendering\RenderingContext. Controllers should
call $view->getRenderingContext() to perform operations instead.
