I tried randomly some examples (with Chrome on Windows 7) but some of them worked only partially and many errors were shown in the browser console.

Is this expected because it is an early release or they should work?

Just to name some of them:
- Grid with Big Data
- Grid with Components in Cells
- some Calendars (after some clicks they show errors in console)

After going back and forth for a while with different examples, this error was shown in console and some examples did not work any more:
[E] DOM element with id selector in Element cache is not the same as element in the DOM. Make sure to clean up Element instances using destroy()

Also the link on top "View Examples" does not work (causes an infinite redirection loop).
