[Typo3-dev] $LANG is always NULL

Thanks for this info.

But I want to use the locallang file from another extension. 
Unfortunately pi_loadLL() does not take any parameter (ext_key).

$label = 
$LANG->sL('LLL:EXT:sr_feuser_register/pi1/locallang.php:missing_'.$check);

This shall be used in tt_products.

$this->langKey = $langKey = 
strtoupper($TSFE->config['config']['language']);	// TYPO3_languages

How can I use the language key $this->langKey to get the correct 
language text for the item?
