Hey Detlef,
You should not need to copy the same file in the frontend. All you need is the joomla API
In your componentname.php file in the frontend you could do (example from hotspots):

$jlang = JFactory::getLanguage();

$jlang->load('com_hotspots', JPATH_ADMINISTRATOR, 'en-GB', true);

$jlang->load('com_hotspots', JPATH_ADMINISTRATOR, $jlang->getDefault(), true);

$jlang->load('com_hotspots', JPATH_ADMINISTRATOR, null, true);

first line loads the admin English file. (this ensures that all strings will have a meaningful translation and not COM_HOTSPOTS_MY_AWESOME_SOMETHING_TEXT...)
the second line loads the language of the site (which can be German for example) And the third line loads the user language. (it can be for example Japanese).

With those 3 lines you can use the same admin language file in the frontend and you don't need to copy files around. 1 location = less things to maintain and less thinks can brake.

Cheers,
Daniel

edit: With this approach you can do even merging. For example you can grab the frontend language file and add it to the backend. Or you can load the files of a module or plugin in your component. Whatever you need...

Hi Daniel,

your suggestion works fine and I have now greatly improved my language translation deployment.

Thanks again.

One problem is still there: manually creating the lang packs from the backend works fine. The webhook link instead creates a corrupt file named ".com_jpodium.zip" in the packages/jpodium folder of my media directory.

I copied the URL manually in the browser and got the same results.

I honestly have no idea what's going wrong.

Thank you again

Detlef

Well, I have not experienced that problem with the webhooks here on compojoom, but I also have the feeling that something there is not 100% ok. So far I haven't been able to track it down. With that said I'm starting to think that the webhooks are not the right way to sync the packs. Maybe a cronjob would be better.

Btw - you are welcome to debug and find out why it is not saving the files properly for you. A pull request is after that always welcome: https://github.com/compojoom/ctransifex

OK, understood. I'll give it a try over the next weekend.
