I use GWT RPC in my application but I don't understand how can I use it here.
I have a grid with data and I want that when user press the "Save" button the data will be saved.
One way to do this is that when button is click a new window will be open with url that include call to servelt and the servelt will return the csv data and the user can make "Save as" to save the data.
Another way is to use the browser download feature.
Is there another way ? how can I use the GWT RPC for this ?
