Our application is a fairly substantial business sales and service app that the client’s field associates use to record their service calls. I managed to take the central feature of our application - the data-driven protocol that the field associates follow - and create a flexible, self-updating tree structure that will basically take all the work out of writing the UI elements. All we have to do now is walk the tree, render the items, and the self-updating structure is smart enough to refresh only the elements that change as the user records their responses.
