[Solved] Tabstrip problem

[Renato]

I have problem on tabstrip. All tab are selected, all have the t-state-active style.
I use it on nopcommerce ecommerce solution.

this is the code 

@Html.Telerik().TabStrip().Name("category-edit-vendor").Items(x =>

{

    x.Add().Text("a").Content("Test");

    x.Add().Text("b").Content("Test2");

   

    EngineContext.Current.Resolve<IEventPublisher>().Publish(new AdminTabStripCreated(x, "category-edit-vendor"));

})

the html generate is 

 <ul class="t-reset t-tabstrip-items">

       <li class="t-item t-state-default t-state-active"><a class="t-link" href="#category-edit-vendor-1">a</a></li>
<li class="t-item t-state-default t-state-active"><a class="t-link" href="#category-edit-vendor-2">b</a></li>
</ul>

Thanks
