TYPO3 11: InfoViewHelper does not work in backend context without a simulated frontend.

[Abdull]

Using

"typo3/cms-*": "-11.3.1"
"fluidtypo3/vhs": "dev-development"

My TYPO3 frontend pages are configured with a Fluid layout using <v:page.header.title title="{v:page.info(field:'title')}" />

When visiting the frontend with a TYPO3 template using , the following exception occurs:

So if I assume correctly, $GLOBALS['TSFE'] is not set, even though the request is in a frontend context.

Any ideas?

This exception does not occur for me in TYPO3 10.

Unfortunately the message is a bit wrong, $GLOBALS['TSFE'] is set. The problem is with the !$GLOBALS['TSFE']->sys_page instanceof PageRepository. The PageRepository namespace in line 13 has changed in Typo3 11 from TYPO3\CMS\Frontend\Page\PageRepository to TYPO3\CMS\Core\Domain\Repository\PageRepository. This change solved the problem for me.

TYPO3\CMS\Frontend\Page\PageRepository is used in several places in the code and they all fail with TYPO3 v11. I don't know what is the proper way solve this in EXT:vhs and maintain compatibility with < v11.

Me too...

Thanks!
