error SamrtRendering

Hi I have the following problem when I try to paint a grid with SmartRendering. Whenever I get a javascript error. With _locator ie is null or not a firefox objto and row is undefined. Any idea what might be going. I put the code:

var xmlLink = “${xmlLink}”;
mygrid = new dhtmlXGridObject(‘gridboxp’);
mygrid.dhx_globalImgPath = “dhtmlx/dhtmlxGrid/codebase/imgs/”;

cadena = “<?xml version='1.0' encoding='iso-8859-15'?>”;
cadena += “”;
if (posStart.equalsIgnoreCase(“0”)){
cadena += “”;
if (!modulo.equals(“T”)){
cadena += “Num. Carga”;
cadena += “Línea”;
cadena += “Ref. Seg. Ai.”;
cadena += “Módulo”;
cadena += “Cif/Nif Asegurado”;

xml += “”;
if (!modulo.equals(“T”)){
xml += “”+cargaId+"";
xml += “”+codLinea+"";
xml += “”+refSegAi+"^datosPoliza.action?plan="+plan+"&cargaId="+cargaId+"&codLinea="+codLinea+"&refSegAi="+refSegAi+"&poliModulo="+poliModulo+"&sitPoliza="+modulo+"^_self";
xml += “”+poliModulo+"";
xml += “”+cif+dni+nif+"";
xml += “-”;
xml += “”;

Please check if you are using last version of dhtmlxGrid.If issue still occurs please provide us complete demo where we can reproduce this issue … leted_demo

Hello. The error was because I had put filters and order and it seems that this can not be. It loads fine me, but I skip the next load when I reach the end of the first block.
