TYPO3 Core

If you have more then one language in an extension llxml-file, only the default language is used. This results in wrong labels.

I tracked it down to this code in tx_lang_parser_llxml.php:

public function getParsedTargetData($path) {
        if (!isset($this->parsedTargetFiles[$path])) {
            $this->parsedTargetFiles[$path] = $this->parseXmlTargetFile($path);
        }
        return $this->parsedTargetFiles[$path];
    }
In this use case, $path is <extpath>/locallang.xml for both default language and additional languages.

A workaround is to move the labels to a file in typo3conf/l10n as the language packs from translation server do.
