The custom autocomplete demo is rather simple...! please try with something which isn't default and see that it does not work.

nothing in the custom section is rendered.... error

no modifications to my code and this works fine in 1.8.3 and 1.9.2 with backward comp disabled.

trying to up to 1.10.0 rc and i can not.
