Tengo una pregunta, cuando la cuadrícula está vacía, ¿por qué muestraPage 1 of 0 no puede serPage 1 of 1 o algo más razonable?

Mi códig

var xml=client.responseText;
         var xmlDoc = $.parseXML(xml); 
         var $xml = $(xml);

         xml=xml.replace(/<productId>1/g, "<productId>"+productMap['1']);
         xml=xml.replace(/<productId>2/g, "<productId>"+productMap['2']);
         xml=xml.replace(/<productId>3/g, "<productId>"+productMap['3']);

Actualiza

Actualicé en consecuencia, pero todavía no tuve suerte, sigo teniendo el mismo viejoPage 1 of 0

 xmlReader: {

Update, algo útil

Si volvemos a cargar la grilla, también resuelve el problema

jQuery("#list1").setGridParam({rowNum:10}).trigger("reloadGrid");
