jQuery Grid Plugin - jqGrid

Dear Tony,

Thanks for all your hard work and support for open community. I am trying to get a sample working but getting weird error cur is undefined. Can you please help me resolve the problem.

  jQuery("#list").jqGrid({
    url:'dailyPL.action?q=2',
    datatype: "json",   
    colNames:['ID','Ticker','Delivery Date', 'Maturity Date', 'Unrealized PL','Realized PL'],
    colModel:[
            {name:'id',index:'id', width:55},           
               {name:'ticker',index:'ticker', width:100},
               {name:'deliveryDate',index:'deliveryDate', width:90, sorttype:"int"},
               {name:'maturityDate',index:'maturityDate', width:100},
               {name:'unrealized',index:'unrealized', width:80, align:"right"},
               {name:'realized',index:'realized', width:80, align:"right"}       
           ],
    pager: jQuery('#pager'),
    rowNum:10,
    rowList:[10,20,30],
    sortname: 'id',
    sortorder: "desc",
    viewrecords: true,  
    imgpath: 'themes/basic/images',
    caption: 'My first grid'
  });

{"page":"1","records":"3","rows":[{"deliveryDate":20080950,"id":"1","maturityDate":20080602,"realized"

:0.0,"ticker":"GE","unrealized":500.0},{"deliveryDate":20080950,"id":"2","maturityDate":20080602,"realized"

:0.0,"ticker":"cSC","unrealized":5000.0},{"deliveryDate":20080950,"id":"3","maturityDate":20080602,"realized"
