setImagePath for Windows on dhtmlxLayout

I have initialized the dhtmlxWindows in various situations and never had problems, however, when I try to initialize it associated with a Layout, the definition of ImagePath does not work.

var mainLayout;
var win_n;

function initMainLayout() {
mainLayout = new dhtmlXLayoutObject (document.body, “2E”);


function initWindowN(){

win_n = mainLayout.dhxWins.createWindow(‘nota_window’, 0, 0, 800, 430);


The code above result in a “TypeError: win_n.setImagePath is not a function”

I will appreciate any orientation.

Strange behavior.
