Why do I get a message saying 'Compression source file vf_multi_LLL.js not found'?
This happens when saving the Framework in a multilingual partition.
When the Framework runs in the browser it uses a file named vf_multi_LLL.js (where LLL is a language code) to access multilingual text string values. There are 3 such files shipped: vf_multi_ENG.js, vf_multi_FRA.js and vf_multi_JPN.js.
Simply copy one of those files with the new name of vf_multi_LLL.js where LLL is the desired language code. These files are located in the partition execute folder.
You will then have to edit and modify the contents to reflect your own language.
