New Revision: 208814

URL: http://svn.apache.org/viewcvs?rev=208814&view=rev
Log:
Update the "list categories" and "list locales" implementations, and unit
tests, to use the new convenience base classes provided by the core library.
Implement a list of state names capability to illustrate use of the
"list completion" facility.

Also, add the beginnings of a very simple Ajax example, providing completion
lookup while using the standard JSF text input component.  It doesn't work
yet, but I need to commit (from the laptop I took to JavaOne) so that I can
work on this with my desktop machine).
