I have been using SmartGWT a lot for a customer's project so I have been generally digging into both the Google Web Toolkit (GWT) and the SmartGWT system that builds on top of GWT. My personal project is a reimplementation of my Rails application for ConsultingWith.me ( very old placeholder page ) in GWT. I plan on writing a few long blog articles about GWT and/or SmartGWT in the near future but for now I have learned a few things that are worth sharing: Plan ahead on designing data models that essentially live on the client side, that support caching on the client side, and efficiently support asynchronous data fetches from the server. The view pages (written in Java, compiled to compact and efficient Javascript) must always make asynchronous calls to the local (in the browser) data model because it is unknown whether the local model has the data or must itself fetch asynchronously from the server.
