Name Binding between Controls and Adapter

Which are the critical parts when building the "Hello World!" application?

There is a name binding between the layout definition and its corresponding adapter. This is the simple and effective approach of the development process: The adapter represents a logical abstraction of what the page displays. All layout definitions are kept in the page - all the logic is kept in the adapter. (Or better: behind the adapter. The adapter itself should only be a facade to the "real" application logic.)

Data Exchange at Runtime

What happens at runtime?

With a standard HTTP connection, only the changed content of the screen is passed when operating on one page. The layout is kept stable in the browser. Consequently, there is no flickering of the page due to page reloading.

All steps described in the list above are done completely transparent to your adapter; i.e. you do not have to cope with session management, stream parsing, error management, building up HTML on the server, etc. You just have to provide an intelligent HTML page by defining it in the Layout Painter and an adapter object.
