Problem with text_field and []

Hi,

I was pleased to see how easy it is to add more then one new items in a form:

form_tag :action => 'update_multiple' do   3.times do     @item = Item.new # create an active record object     text_field 'item', 'name'   end end

the action "update_multiple" now gets a list of the three items (params[:item]). Wonderful.

It even works for already known items / items from the database:

form_tag :action => 'update_multiple' do   @item = Item.find(1)    text_field 'item', 'name'

  @item = Item.find(2)    text_field 'item', 'name'

  @item = Item.find(3)    text_field 'item', 'name' end

Here also "update_multiple" gets the list...

...but I would not post here if I don't have a problem.

If I mix both using some new und some known items than I get an server error:

form_tag :action => 'update_multiple' do   # show some "old" items   @item = Item.find(1)    text_field 'item', 'name'

  @item = Item.find(2)    text_field 'item', 'name'

  # add three new items   3.times do     @item = Item.new # create an active record object, which doesn't have an id yet     text_field 'item', 'name'   end end

this leads to the error 500-message. When I look into the log file the following entry comes up:
