title: select_tag rails 3 wrong number of arguments error
body: <p>I have this select_tag using Rails 3</p>
  
  <pre><code>&lt;%= select_tag :area_id, options_from_collection_for_select(@areas.sort_by(&amp;:name)), {:onChange =&gt; remote_function(:with =&gt; "'filter_by='+value", :url =&gt;{ :controller=&gt;"encoder/members", :action=&gt;"filter_schools" } ) } %&gt;
  </code></pre>
  
  <p>But I kept on getting the error "wrong number of arguments (1 for 3)." What could be wrong?</p>
