  },
    rowNum:-1,
    sortname: 'servico',
    sortorder: 'desc',
    viewrecords: true,
    gridview: true
  });
});

I load the grid with the method on my javascript using ajax

var mygrid = jQuery("#listlog")[0];
mygrid.addXmlData(xmlHttp.responseXML);

i don't really have the example.php file, mentioned on line
url:'example.php',
but works fine on FF, if i remove the line, the grid are not created.

i tryed to use
  $("#statuslist").jqGrid({
    autowidth:true,
    datatype: 'local',
    mtype: 'GET',

    and the line on my javascript
    
    var message = xmlHttp.responseText;
    jQuery("#statuslist").jqGrid('setGridParam',{datatype:'xml'}).trigger('reloadGrid');
    mygrid.addXmlData(xmlHttp.responseXML);
    
But didn't works too.

thanks
