Replace_html in 2.2.2

Hello, I'm in troubles with an easy thing I've done several times, but I don't see what I'm doign wrong.

Having index.html.erb:

<h1>Projects</h1>

<div id="new_project"> </div> <table>   <tr>   </tr>

<% for project in @projects %>   <tr>     <td><%= project.name %></td>     <td><%= project.description %></td>     <td><%= link_to 'Show', project %></td>     <td><%= link_to 'Edit', edit_project_path(project) %></td>     <td><%= link_to 'Destroy', project, :confirm => 'Are you sure?', :method => :delete %></td>   </tr> <% end %> </table>

<br />

<%= link_to_remote 'New project', :url => new_project_path %>

new.rjs:

page.replace_html "new_project", :partial => "new", :object => @project

and finally _new.html.erb:

SOME TEXT

When I'm within index.html.erb and click on 'New project' link, I see this log in the console:

Processing ProjectsController#new (for 127.0.0.1 at 2009-02-16 18:08:12) [GET]   Parameters: {"authenticity_token"=>"1efcdedfb3b680581058efa75cdbc143bf880b65"}   SQL (0.1ms) SET NAMES 'utf8'   SQL (0.0ms) SET SQL_AUTO_IS_NULL=0   Project Columns (0.7ms) SHOW FIELDS FROM `projects` Rendering projects/new Rendered projects/_new (0.2ms) Completed in 11ms (View: 2, DB: 1) | 200 OK [http://localhost/projects/ new?authenticity_token=1efcdedfb3b680581058efa75cdbc143bf880b65]

but nothing happens, thus is, it doesn't replace the 'new_project' DIV. What I'm doing wrong, because I can't see it.

Thanks in advance.

I can answer myself. I didn't notice that in Rails 2.2 I need to make changes in the controller's action to respond to JS.

  def new     @project = Project.new     @states = ProjectStatus.all.collect {|s| [s.name, s.name]}     respond_to do |format|       format.html # new.html.erb       format.js # new.js.rjs <--------------------------------- HERE!     end   end

This is a thing I don't like with new releases of Rails, they always broke backwards compatibility...

Hi, you should never upgrade without reading the release notes and how it may effect your current application.

Good luck,
