Actually I think I'm close to a solution now. I made these two methods:

def fields_for_setting(namespace, name)
  id = "settings_#{namespace}_#{name}_"
  m = Builder::XmlMarkup.new :indent => 2
  fields_for "settings[]", setting = 
Setting.find_or_initialize_by_namespace_and_name(namespace, name) do |f|
    m.p do
      unless setting.new_record?
        m << (f.hidden_field :id, :index => nil, :id => id+"id")
      end
      m << (f.hidden_field :namespace, :index => nil, :id => 
id+"namespace")
      m << (f.hidden_field :name, :index => nil, :id => id+"name")
      m << yield(f)
    end
  end
end

def text_field_for_setting(namespace, name, label=nil)
  namespace = namespace.to_s
  name = name.to_s
  label ||= "#{namespace.capitalize} #{name}"
  id = "settings_#{namespace}_#{name}_"
  fields_for_setting(namespace, name) do |f|
    f.label :value, label, :index => nil, :for => id+"value"
    f.text_field :value, :index => nil, :id => id+"value"
  end
end

In my view I'm calling the second method (text_field_for_setting) like 
this:

= text_field_for_setting(:site, :owner)

The method that is called here then calls my first method 
(fields_for_setting) with a block. This actually works fine, but for 
some reason that I can't figure out (I hope you can help me) It only the 
LAST line of the block that is passed to fields_for_setting that shows 
up.

In other words, even though I declare both a label and a text field, 
only the text field shows up. How comes?
