basically the code inside the <%
person_form.fields_for :address do |address_form| %> is not
executed. i.e in the html page the label and edit boxes for address is
not displayed to the user. and if you look at view source you dont see
the html tags for them. if you move this code below inside fields_for,
no object information is displayed.

<%= debug(@person.address.attributes) %>
<%= debug(@person.address) %>

if there is better way (work around) to handle one-one mapping.
please let me know as well.
