I'm building a Project Management app using jqGrid and Joomla and everything seems to work just fine except for one thing.

I cannot read the rows, page, sord and sidx params added in the url from jqGrid.

Using the configuration bellow

$(function(){ 
  $("#list").jqGrid({
    url:'index.php?r=Controller/Action&tmpl=json',

my index.php file instantiates the class Controller and executes iits method Action .

Inside the method i can read the r and tmpl params but not the others regarding sorting and pagination.

Any ideas?

Thanks in advance
