@nathanvda - I have made sure the rest of codes are exactly like as your demo example.

Using:
rails (4.1.8)
simple_form (3.1.0)

undefined method `reflect_on_association' for NilClass:Class

When you called:

<%= link_to_add_association 'Add', f, :study_plan_subjects %>

The rest of code are exactly like this example.

1. Downloaded and ran the cocoon_simple_form_demo.
2. Create a project and add a few tags (has_many through) and save.
3. Edit the project, clicking remove on some/all the tags and click "update project" to save
4. Tags which were "removed" are still present on the project. The association should be deleted.

It's not clear why we're including therubyracer in the Gemfile.

if during rake db:migrate the following error occurs:
NoMethodError: undefined method last_comment' for #<Rake::Application:0x007f2e4ce09cd8>
then a quick fix can be edit ./Rakefile and add these lines before calling Rails.application.load_tasks

require File.expand_path('../config/application', __FILE__)
require 'rake'

+ module TempFixForRakeLastComment
+   def last_comment
+     last_description
+   end 
+ end
+ Rake::Application.send :include, TempFixForRakeLastComment

CocoonSimpleFormDemo::Application.load_tasks

sorry, not the good place for that...

They seem to be all stubbed out '#'. On the create new Project page, none of the links work. Browsing through the code the js seems to be there, but not sure why they aren't working.

How would I go about displaying images from a partial in a view using this gem. For example, I have a profile that has many products. In my view I have something like this for text fields:

<% @editprofile.products.each do |product| %>
     <strong>Product/Service:</strong>
      <%= product.prodserv %>
      <strong>Product Description:</strong>
      <%= product.productdesc %>
  <% end %>

What should I put to display images from the product partial?

Product Partial:

<div class='nested-fields'> 
  <p><b> Product (s) Name (Max 75 characters): </b></p> 
  <%= f.input :prodserv, label: "Products" %>  
  <p><b>Description</b> (Maximum 500 Characters)</p>
  <%= f.input :productdesc, label: "Product Description" %>
  <p><b>Upload Pictures: </b>(Note: You can upload a total of two files (picture, audio, video, ppt, MSWord, Excel)
        for each product or service)</p>
  <%= f.file_field :upload %>
  <%= f.file_field :upload2 %>
  <p><b>Attached Product Information</b></p>
  <%= f.file_field :urlimage %><%= link_to_remove_association "remove url", f %>
  <%= f.input :url, label: "Product URL"  %>
</div>
