sorry, i guess i could have explained that better. my option prividing
and selection works just fine, but my use for the autocomplete is such
that when an option is selected i would like to trigger an asynchronous
server request/response.
previously (in tapestry4.1) i've done this by submitting the containing
form asynchronously by providing a listener with the following annotation:
@EventListener(targets = "myComponent", events = "onValueChanged")
public void myListener()...
at this point i would update some components on the page and run some
more javascript.
i imagine there's something similar in tapestry5 but it's not obvious to
me yet.

just further to that, i'm new to tapestry5 and haven't completed my
reading on ajax etc,
but how would i listen for the 'something selected from list' event
(for the autocomplete mixin), and do some asynchronous server side
processing?
From the Autocomplete page:
http://tapestry.apache.org/tapestry5.1/tapestry-core/ref/org/apache/tapestry5/corelib/mixins/Autocomplete.html
Just create a method
List<String> onProvideCompletionsFrom[component id](String string) {
// return a list of string containing the suggestions.
}
I'm not sure I understood what you meant, but Tapestry handles all the
AJAX plumbing for you automatically. Just handle the event triggered
by the component, mixin or page. Writing a method to handle an AJAX
request triggered by a Tapestry component, mixin or page event is done
exactly in the same way non-AJAX events are handled.
Each component and mixin defines which events they triggers and how
they process the value returned by the event handler method.
