So here's the scenario:

User:

has_one :company
accepts_nested_attributes_for :company

Controller:

@user = User.new
@user.build_company

View:

<% semantic_form_for @user, :url => register_path do |form| %>

  <h2>User Information</h2>

  <%= form.inputs %>

  <h2>Company Information</h2>

  <% form.semantic_fields_for :company do |company| %>
    <%= company.inputs %>
  <% end %>

  <%= form.buttons %>

<% end %>

After scouring the web, this SEEMS like it should work. However, all I get are the user inputs. The "semantic_fields_for :company" block outputs nothing at all...

Am I missing something here, or is this perhaps a Rails 3 bug to do with Formtastic?
