Rails3: Display validate errors in a multi-model Form?

Is posible create this kind forms with displaying errors like a simple model? https://i.sstatic.net/vEWkD.png

I get create two models... but if I fill incorrectly the form.. the errors messages won't appears and error Rails screen say me, for example, "validation failed: field1 can't be blank..."

Models:

class Step < ActiveRecord::Base

  #validates
  validates :tree_id, :presence => true, :numericality => true
  validates :is_first, :presence => true, :length => {:maximum => 1}
  validates :status, :presence => true, :numericality => true
  validates :step_type_id, :presence => true

  #relations
  belongs_to :step_type
  belongs_to :tree
  has_many :statements

  accepts_nested_attributes_for :statements 

end

class Statement < ActiveRecord::Base

  #validates
  validates :step_id, :presence => true, :numericality => true
  validates :title, :presence => true, :length => {:maximum => 255}
  validates :statement, :presence => true
  validates :help, :presence => true
  validates :is_last_version, :presence => true, :length => {:maximum => 1}


  #relations
  belongs_to :step
  has_many :transitions

end

any example or suggestions?

Do you have the following lines in your view?

<% if @statement.errors.any? %>
  <% flash[:notice] = "Please correct!" %>

    <% for message in @statement.errors.full_messages %>
        <li class="cf-messages-li"><%= message %></li>
    <% end %>

<% end %>
