Nested objects return extra nil array

Can't reproduce unfortunately, anyone else?

Automatic cleanup of spam.

If it was doing a build by default wouldn't that be reflected in the db? Why would Comment.count show 0 and then my app gets an extra comment?

This app is pretty much word-for-word from the rails guide for the blog app...
http://guides.rubyonrails.org/getting_started.html

I'll repost critical elements here to make it easier.

comments controller:

class CommentsController < ApplicationController
 def create
  @post = Post.find(params[:post_id])
  @comment = @post.comments.create(params[:comment])
  redirect_to post_path(@post)
 end
 def destroy
  @post = Post.find(params[:post_id])
  @comment = @post.comments.find(params[:id])
  @comment.destroy
  redirect_to post_path(@post)
 end
end

class Comment < ActiveRecord::Base
 belongs_to :post
end

class Post < ActiveRecord::Base
 validates :name,  :presence => true
 validates :title, :presence => true,
 has_many :comments
end

Interestingly I found in the form:

<h2>Add a comment:</h2>
<%= form_for([@post, @post.comments.build]) do |f| %>
  <%= f.error_messages %>

  <div class="field">
    <%= f.label :commenter %><br />
    <%= f.text_field :commenter %>
  </div>
  <div class="field">
    <%= f.label :body %><br />
    <%= f.text_area :body %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

If I changed the @post.comments.build object to @post.comments.new, it stopped returning a nil object in the array.
