I'm using version "2014.2.716"
In this version calling tabStrip.select() will return an empty array if there is no tab selected. I see this behavior is different in later versions, where the TabStrip widget instance is returned instead.
So, my question is, what is the official way to determine if a tab is currently selected or not?
By the way, it's changes like this that have made our adoption of newer releases of the framework slow/painful. Looking through KendoUI Release History
I don't see any breaking changes listed for TabStrip - yet, here is one.
