Why do I get a message saying 'Compression source file vf_multi_NAT.js not found'?
This happens when saving the Framework in a monolingual partition.
When the Framework runs in the browser it uses a file named vf_multi_LLL.js (where LLL is the language code) to access multilingual text string values. There are three such files shipped: vf_multi_ENG.js, vf_multi_FRA.js and vf_multi_JPN.js.
If the language of your monolingual partition is English, French or Japanese, simply copy the file corresponding to your language with the new name of vf_multi_NAT.js. These files are located in the partition execute folder.
If the language of your monolingual partition is none of the above, copy the file but also edit it and modify it according to your own language.
