This error occurs if you add the same control twice to the control tree. The PageViewCreated event is fired whenever a new PageView object is added - you need to populate the controls inside the PageViewCreated event.

Thank you Albert for your response,
I am still confused however, my logic seems to follow the online sample, what specifically is missing or is in the wrong place?

Please find below a slightly modified version of the JS function that should do the trick.
| <script type="text/javascript"> |
| function onTabSelecting(sender, args) |
| { |
| if (args.get_tab().get_pageView()) |
| { |
| if(args.get_tab().get_pageView().get_id()) |
| { |
| args.get_tab().set_postBack(false); |
| } |
| } |
| } |
| </script> |
