Rails - May 2009 - select_tag with multiple set to true returns a String in params instead of array

Hi - I''m trying to get a multi-select box working.  The form shows up
fine, and I can select multiple items fine, but in the controller, the
parameter shows up as a single string, instead of an array of values.
Any ideas?

The form:

<%=select_tag "items", @items, :multiple => true :onchange =>
"this.form.onsubmit();"%>

The form goes to function update_items in the controller, which fires
just fine.  But params[:items] is a single string value.

Thanks in advance for any help.

use "items[]" for the first parameter ? (I though rails might do this
automatically, obviously not)
