Hi, Are there any plans for, or has anyone worked on, something that will allow me to use autocompleter components in a cascading manner, whereby a selection in one will affect the URL params sent to another? The simplest solution, as I see it anyway, would be to add a callback that happens just before the request is sent, that would allow changes to be made, but this would require me to modify Scriptaculous code, and I''d rather avoid that. Does anyone have any other suggestions?

In the hope it helps someone else:
It turns out there''s an option for this very thing, it just
wasn''t in
the wiki-docs (I''m about to go and add it).
You just need to attach a ''callback'' to the options hash, that
returns
the querystring you want sent to the server, allowing anything else to
be attached to it. Slight gotcha, what you return is used instead of
the defaults, rather than instead of. A quick example- I wanted
selecting a person''s name to be further restricted if a company had
already been chosen:
var options = {
callback: function(field,querystring) {
if($F(''company_id'')) {
typed+=''&company_id=''+$F(''company_id'');
}
return querystring;
}
};
