Introduction
First of all, if you haven't yet read article Localization of Ext Applications, do not continue here but read it now please (or the example might not make any sense).
Now, this example is somehow different from others for other examples demonstrate how to use various aspects of Ext, best coding practices or practical solutions - they illustrate how to use what we have. This one shows what we could have. It tries to implement an ideal localization system and it is in the development stage of "concept proof."
It is not complete and it has issues, nevertheless, when completed and debugged, it might become the localization platform we always dreamed of.
Note: The idea is not mine but, I think, Mitchell Simoens is the author of the fiddle that inspired me. I have simplified it and made it more coherent with the ideals I describe in the above article.
