Attach dhtmlxWindows in dhtmlxtabbar

Hi, i’m newbie in using dhtmlx…
how to attach dhtmlxWindows in dhtmlxTabbar?
when i include dhtmlxContainer.js, tabbar doesn’t appear…


could you provide a sample to recreate the problem locally

i’ve included in my page :

when i run in browser (firefox), there comes up error messasge from error console :
“Error: is undefined
Source File: localhost/myapps/vsianalisator/c … xtabbar.js
Line: 91”

Try to use the dhtmlxtabbar.js that is attached here:

Possibly it’ll resolve the problem. If the problem still occurs, we need the complete demo to recreate it.
