grid.setDateFormat doesn't work mysql

Hi, the function dateformat doesn’t work on mysql and tomcat6, but on db2 and tomcat5 works! am I doing something wrong here or there is some other issue?
thanks! Laura.

i have pro version.

grid = new dhtmlXGridObject(idDivGrilla);
grid.setImagePath("…/js/DHTMLX/dhtmlxGrid/codebase/imgs/");
grid.setDateFormat("%d/%m/%y");
grid.setHeader(“1,2,3,4,5,6,7”);
grid.setInitWidths(“0,0,100,200,300,200,30”);
grid.setColTypes(“ro,ro,dhxCalendar,ro,ro,ro,img”);
grid.setColSorting(“na, na, date,str,na,str,na”);
grid.init();
grid.loadXML(url);

<?xml version="1.0" encoding="iso-8859-1"?> 1 1 2010-11-02 Administrador admin ....

change it as

grid.setDateFormat("%d/%m/%y","%y-%m-%d");

first parameter - format which you want to have in grid
second - format which you are using in XML

genius! thanks!
