Content element not visible if language is set to All Languages [-1]

[Scopestyle]

TYPO3 version 10.4.25
Container version 1.5.0
Behaviour tested on multiple projects.

Problem:
On a multilanguage TYPO3 installation, whenever a content element in a container is set to All Languages [-1] this content element disappears from the container. Showing this container as empty in the Page view.

Does anyone have a solution for this?

I can confirm this problem.

TYPO3: 10.4.26
Container: 1.5.0

I assume that this problem is caused by container/Classes/Domain/Factory/PageView/Frontend/ContainerFactory.php:102.
It is still the sys_langauge_uid 0 used even if the sys_langauge_uid is set to -1 (all languages).

yes, sys_language_uid=-1 is not implemented/not supported. The Extension has a strict language policy (either a container is connected or free mode). We decided to not support -1, focus is on stability and integrity of container and container-children CE.

closed due sys_language_uid=-1 is not supported
