They exist in the development system but when I export the main application and import it with another ID in the production system the translated applications aren't includedWhen you export main application, you will only get main application. In latest versions of APEX ( 4.1 or later), you have option to specify whehter to include all translated application as-well or not. In earlier versions, you have to manually export all translated applications by yourself and you need to install them on Production environment. I do this regularly for our applications. Fortunately we use same application ids in all environments. So I have not tested with different application ids.
