GX-Bug #69052
Von Mirko Janssen vor etwa 3 Jahren aktualisiert
It's not possible to use `0` as parent group ID in the legacy `AdminAccessService`, which would be needed to create a new access group as a top-level access group.
Additionally, developers should also be able to use lower case language codes in the `KeyValueCollection` for language-dependent data (name and description).
Furthermore, it's important to update the [developers' documentation](https://developers.gambio.de/tutorials.html?v=4.5.1.0_beta1&p=verwendung-der-zugriffsverwaltung) as well!
## Steps to reproduce
See attached forum post.
## Expected results
Should be possible to create a new access group with the given code snippet.
