I've implemented Sam's solution in my project (thanks Sam !).
When the page is refreshed with the new items in the drop down list, i
would like that this form element keep the focus but the focus is reset
to the first element in the form ...
Any advice is welcome.

I do this frequently, but I reload the entire page so that it doesn't
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.

But what about the errors that would come up during the rewind of the
form data ?
