So I have a rails 3.2.11 Example app that exhibits some simple core use cases and I am starting again under rails 4.0.0.beta1

    <div>

        <%= f.fields_for :interactions, s.initialized_interactions() do |builder| %>
            <% role = builder.object.role %>
            <%= builder.hidden_field :role_id %>

            <div class="field">
                <%= builder.check_box :enable %>
                <%= builder.label :enable, role.name %>
            </div>
        <% end %>
    </div>

 So the above renders OK for 3.2 but under rails 4.0 'builder.object' is an array of role objects and of course it fails.

Any ideas ?

Have you tried to display builder.object on screen, or in rails console? If you do it both in 3.2 and 4, you should be able to see if there is a difference.
