datatable callback fields validation

unixssh

Hi there,

I have a form with some fields, i sumbmit those fields like params in sAjaxSource url, i get the json data from server to populate datatable, all of these works like a charm. My issue is related to validation of these fields. If one fields is not populated i want to get from the server a flag and display in page a validation message and i don't know how tot do this using sAjaxSource callback(server side i' use spring mvc)

I tried to find an answer for this issue but i couldn't, any advice would be appreciated :)

Thanks
