i use  docs.jquery.com/UI/Tabs

I created correct tab interface using this plugin and it works.

But i wanted in one of tab mentioned above create another collection of tabs. And here is a problem.

When i am callling tabs() on this inner collection of tabs it creates only class .ui-tabs for this collection, but doesnt create any classes for childs of this collection: i dont have classess .ui-tabs-nav .ui-tabs-panel etc. So inner tabs doeesnt work

Is there any solution for this? Firebug doesnt show any js problem. 

I use jQuery.noConflict method
