Error in the Example Code?

Hi all,
I think I have found a mistake in one of the examples. See link below.

http://editor.datatables.net/release/DataTables/extras/Editor/examples/joinSelf.html

When I start editing an entry in the example,the values stored in the selectbox are not selected. It's always only the first entry of the selectbox active. I just got the exact same problem/error. What can I do to change that?

Thanks a lot!
