Check out the example here: http://dojo.telerik.com/@tom.matty@bentley.com/otEye
Basically when you use both the list isn't rendered properly. You will see 4 items in the list which is correct but the dataItem's are out of sync with the option label at the end. Not sure if using incorrectly or not but in example you will see if you choose the last item in the list it will select Baz even though it's a blank option. And selecting the first option gives you the blank option.
