Bug Report

Current Behavior

If you enabled the Deprecation log, log entries are triggered once you call the Backend Module, like

Wed, 26 Jan 2022 18:09:16 +0100 [NOTICE] request="3bfe5d1fdb640" component="TYPO3.CMS.deprecations": Core: Error handler (BE): TYPO3 Deprecation Notice: TYPO3\CMS\Fluid\ViewHelpers\Be\ContainerViewHelper will be removed in TYPO3 v12. in /var/www/html/httpdocs/typo3/sysext/fluid/Classes/ViewHelpers/Be/ContainerViewHelper.php line 84 

and

Wed, 26 Jan 2022 18:09:16 +0100 [NOTICE] request="3bfe5d1fdb640" component="TYPO3.CMS.deprecations": Core: Error handler (BE): TYPO3 Deprecation Notice: Method makeShortcutIcon() is deprecated and will be removed in v12. Please use ShortcutButton->setArguments() instead. in /var/www/html/httpdocs/typo3/sysext/backend/Classes/Template/ModuleTemplate.php line 587

Those entries are generated from

• the <f:be.container/> ViewHelper (https://github.com/lochmueller/staticfilecache/blob/master/Resources/Private/Layouts/Backend.html#L1)
• and the <f:be.buttons.shortcut/> ViewHelper (https://github.com/lochmueller/staticfilecache/blob/master/Resources/Private/Layouts/Backend.html#L25)

Both are deprecated and should be avoided for Typo3 v11.

• https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/11.0/Deprecation-92132-DeprecatedViewHelperFbebuttonsshortcut.html

Expected behavior/output

No deprecation log entry :)

Environment

• TYPO3 version(s): ^11.5.5
• staticfilecache version: ^12.4.3
• Is your TYPO3 installation set up with Composer (Composer Mode): yes

Possible Solution

Follow the Migration section in the mentioned links above... but to be honest, idk if this also works in Typo3 v10 simultaneously.

Thanks @m41r I think this is the same as in this fix: https://github.com/lochmueller/calendarize/commit/5f91b739cdcc009c6eedebd0d94005b6d927fc65 I will check this shortly.
