[ic] actionmap and mv_nextpage in forms

mv_nextpage is not a URL -- it is a page name. ActionMap depends on it being the URL
referencing the site.. You need:

<form action="[area process]">
  <input type="hidden" name="mv_todo" value="refresh" />
  <select
		name="mv_nextpage"
		onchange="
			this.form.action=this.options[this.selectedIndex].value;
			this.form.submit();
		">

    [query type=list prefix=bar sql="select id, display_name from bar where foo='[scratch foo_code]'"]

       <option value="[area foo/[sql-param code]/bar/[bar-param id]]">[bar-param display_name]</option>

    [/query]

  </select>
  <input type="submit" value="Switch Bar">
</form>

It won't work without JS, though.
