Is the valueChangeListener supposed to return a String? I was under the
impression that it's supposed to return void, like
ValueChangeListener.processValueChange(ValueChangeEvent event).
Why would it be complaining about the component id?
I wasn't quite clear enough in my description. This particular select box
is expected to contain, and to submit, several items, so the mutator
(setter) will also take an array. It's a Collection, owned by a user.
