Subject: adding items to a list?

hi, i'm trying to work this out and been using a bit of the 'blog in 15
minutes' code to basically add a new item to a list from within the
'show' action of the list.

much like how when in the example blog app you view a post and can add
comments to it on the 'show' page.

here's the item model

class Item < ActiveRecord::Base
  validates_presence_of :body

  belongs_to :list
  acts_as_list :scope => :list
end

and the list model

class List < ActiveRecord::Base
  validates_presence_of :title

  belongs_to :user
  has_many :items, :order => "position"
end


and within the show list page i've got a 'add item' form

  <% form_tag :action => "item", :id => @list do %>
  <%= text_field "item", "body", 'size' => 15 %>
  <%= submit_tag "Add" %>
  <% end %>

that fires this action

  def item
    @item = List.find(params[:id]).items.create(params[:body])
    flash[:notice] = "added your item."
    redirect_to :action => "show", :id => params[:id]
  end


it all works pretty well alas no item gets created, any ideas?

pulling my hair out on this one...
