Load language files inside custom library

Question

I have a a library inside \libraries\mylib\.

That library contains an include.php which uses following to load language files that are also inside a /language folder in the library:

$lang = JFactory::getLanguage();
// load english language file if some constants are not translated
$lang->load('mylib', JPATH_SITE . '/libraries/mylib', 'en-GB', true);
// load active language file
$lang->load('mylib', JPATH_SITE . '/libraries/mylib', null, true);

My site uses the two languages German and English. The folders inside the library look like this:

\libraries\mylib\language\de-DE\de-DE.mylib.ini
\libraries\mylib\language\en-GB\en-GB.mylib.ini

Now to the problem.

German is setup as the the standard language inside Joomla. So if I run the site in german, the language files in the library get loaded correctly, as shown by the language debugger:

**Loaded** : JROOT/libraries/mylib/language/en-GB/en-GB.mylib.ini
**Loaded** : JROOT/libraries/mylib/language/de-DE/de-DE.mylib.ini

If i switch the language to english the library languages don't get loaded anymore:

Not loaded : JROOT/language/en-GB/en-GB.mylib.ini

Looks like in english the whole library folder path gets lost...?

I checked everything like filenames, parsing errors, folders ans so on. No idea whats going on.

Maybe someone has an idea. Thanks!

Extension-specific language folder is an old and not recommended way of handling language files. Joomla! is moving towards the use of only global language folders. Whether or not your code should still work I can't tell, you might want to ask this on the Issue Tracker.

Until you receive a response there you can workaround the issue by loading your files later during onAfterRoute event or by moving to use the global language folders as well.
