Problem/Description¶

The following TypoScript condition doesn't throw a deprecation in the frontend (and works like it should work):

[{$thm.debug} == 1 && getTSFE().beUserLogin === 1 || applicationContext matches "/^Development/"]

Problem¶

On (every) request in the TYPO3 backend (like the TYPO3 About module) a deprecation message is generated:

It seems like if an extension does load TypoScript in the backend context (in this example it's https://github.com/lochmueller/autoloader/, https://github.com/lochmueller/faq/), the getTSFE().beUserLogin ExpressionLanguage object doesn't exists.

ToDo(s)¶

• Is it necessary, to add a check in the "ExpressionLanguage part" of TYPO3? Other ExpressionLanguage function could be affected as well - Unfortunately I am not deep inside that part of TYPO3.
• Are there any other areas in the backend (e.g. a custom backend module) where the problem might arise?

At time of writing / last editing this issue:
- affected TYPO3 version: 9.5 and dev-master (10)
