This time I will describe a CRUD application using GXT Grid and HttpProxy on the client side and on the server side I use PHP and PDO to access a PostgreSQL database.
The communication between client and server side is using JSON then you can use whatever language on the server side that produce a JSON output.
The source code is on github https://github.com/poseidonjm/GXT3-PHP is structured using GWTP and GWT Editor for binding.
