I am not really understanding your question? we are not creating any json
object in browser. I believe that 's what we want to do in the normal form
submit create the json object.
This is just a simple example to demonstrate the Ajax round trip. Here
bascially you get the updated data back. This can happen if we have form
submit and a grid which gets updated on the form submit.
Can you please look into the below example and provide some solution. I have
copied both the html and java code. If you can tell me how to handle the
data in wicket and send it back in the below example that would be great. I
am not receving the form post data in the request object in wicket.
Thanks
