smartRendering is not working

Suite and Optimus Suite 5
#1

…
mygrid.setAwaitedRowHeight(25);
mygrid.init();
mygrid.enableSmartRendering(true);

data = ‘{“data”:[’;
data += ‘a,b,c,d,e,f,g… many datas …’;
data += ‘]}’;
mygrid.parse(data, ‘js’);

grid rows disappeared… I think smartRendering is not working… why?
