I have facebook_form_for something like the following:

<% facebook_form_for :some_obj, SomeObj.new, :url=>some_objs_url do |f| %>
  <%=f.text_field(:field1, :label=>"Field1") %>
  <%=f.collection_select :field2,SomeObj.types,:type, :name, :label=>"Type" %>   

  <%= f.buttons 'Create!' %>
<% end %>


Instead of one hash of params, I get two:

"someobj"=>{"field1"=>"xxx"},
"some_obj"=>{"field2"=>"0"},
