First of all, when I open that example, immediately a new tab is popped up in the TabPanel, and I have the following message displayed in the tab:

The tab heading is: [no name]
Then, when I try to view the Tab'e Source code, I get the following ASP.NET error:

Frankly, I cannot also understand what this example is trying to demonstrate.
