Dataprocessor for render_array

I have created a grid using render_array of java connector. Now I want to track changes in the grid and want to use dataprocessor how do I do it? How can I get changed rows and write my own data processor which gets changed data and then saves the changes back to grid using render_array java itself?

You can init dataprocessor in normal way, same as in tutorials, and point it to the same servlet, which renders data with render_array.

On server side, in servlet file, you can attach custom saving logic through beforeProcessing behavior … foreupdate
