I've been reading the api documentation, but don't really understand how I'm supposed to work with GXT when dealing with JSON data received from HTTP requests. My client does HTTP requests that return JSON strings. Those strings are related to a model in the server. I want to recreate the model in the client, and work with it: showing trees, tables, and information of the model. The server, as you would imagine, is not a servlet, it's a server that provides the JSON services through HTTP GET requests.
Is there any example of working in such scenario? Any help would be appreciated.
