Excellent progress Ruchira. We need to have a discussion on tooling .. can you please grab me for 5-10 mins today? Lets come up with a plan to build a plan :).
On the JSS model below, what happens to any code that's in the file outside of any function definitions? Also, should we consider placing JS files that execute on the server like this in a separate location rather than use a different extension? That's the model with servlets - and its useful and necessary when the server side code starts importing other stuff to use. We could simply use "WEB-INF" too as that special directory .. Sanjiva.
