I’m trying to pass a hidden field (item\_property) to the add\_link  
helper function but when I do it the process threads start eating up  
memory and my computer freezes.

`
  def add_link(name)
    link_to_function name do |page|
      page.insert_html :bottom,:partial, :partial => 'item', :object
=> Item.new(:item_property => "Some text") #adding this parameter
creates a problem
    end
  end`

`
...
<%= f.hidden_field :item_property, :index => nil %>
<%= f.text_field :item_text, :index => nil %>`

`
<%= add_link "+Add Field Dinamically" %>`  
Does anybody know how to define a property of a new object in this  
context? I’ve been trying to figure it out for a month, so any help is  
very appreciated.  
Thanks
