jQuery Grid Plugin - jqGrid

Hi,

I am using "jquery.autocomplete.js" downloaded from trirand.com .Everything is fine if we proceed normally  i.e. type some character ,wait for autocomplete to return matching words then do tab.But if we type some character,without waiting for autocomplete to return ,do a tab ,it breaks .

Code to hook up autocomplete with 1st cell

$(elem).autocomplete("Services/Service.svc/FundsAutocomplete", {
   
   extraParams: { client: $.trim($get("TradeClientS3D").value), type: 'ShortName' },
   dataType: 'json',
   maxItemsToShow: 10,
   //mustMatch: true,
   parse: function(data) {
    var items = data;
    var parsed = [];        
    for (var i = 0; i < items.length; i++) {
     var abbrcode = Sys.Serialization.JavaScriptSerializer.deserialize(items[i]);
     parsed[i] = {
      data: [abbrcode.First],
      value: [abbrcode.Second],
      result: [abbrcode.First]
     };
    }

    return parsed;
   }
  });
