As anybody done this AJAX way, without a full page reload.
I'm thinking of extending the dropdown and tacos:Autocompleter to add this
kind of behaviour. The only thing we want to get is an updated select, so,
this would be the best solution.
As anybody done this before? Any pointers? I'll pick this up next week so if
someone has a good starter it will boost it up!

get out of sync with rewind.
Declare your form like this:
<component id="form" type="Form">
<binding name="listener" value="listener:doSubmit"/>
<binding name="refresh" value="listener:doRefresh"/>
<binding name="delegate" value="beans.delegate"/>
</component>
Then, within the html element that will become the drop down, include
the following:
onchange="javascript:this.form.events.refresh();"
This will cause the form to call your refresh listener (which bypasses
validation), so you can change values before the form is rendered back
to the client. Then a submit button will call the submit listener,
which will perform validation and let you treat the form as though it
was submitted.
