In dhtmlxlayout,dhtmlxwindow can’t be show,why? The same code work correctly in normal jsp file without dhtmllayout.

#2

dhtmlxWindows can be shown in dhtmlxLayout’s cell.
You should do the following:
1. Create an object on the page;
2. Attach it to layout’s cell;
3. Create a new instance of dhtmlxWindows;
4. Attach viewport to object inserted into layout’s cell.
