Rails - Aug 2006 - paginate, search, sort with ajax problem

hello I hope somebody can help me figure this out.

found this great tutorial at http://dev.nozav.org/rails_ajax_table.html. 
got it working except for one thing.

I can''t seem to make the pagination work. The link_to_remote defined in
the helper is pointing to the wrong url.

I have set up things like so:

defined a search method in de project_controller located in 
apps/admin/project. In de tutorial the method is called list. defined in 
the item_controller

I copy and paste the helper methodes to project_helper in the folder 
helpers/admin/project_helper

The files that create the view are located in views/admin/project

Problem is that the helper method pagination_links_remote and 
sort_link_helper crate a link like the folowing: 
http://localhost:3001/admin/admin/project/search?query=we&sort=name

where is should look like this to make the pagination work:

http://localhost:3001/admin/project/search?query=we&sort=name

notice the diference near "admin", printed only once.

I think I have to ajust the helper methods but I don''t know how, please
help

Post your helper code.

the view:

<p>Nothing found...</p>

<% else %>

<p>Number of results: <b><%= @total %></b></p>

<p>

<% if @user_pages.page_count > 1 %>
Page&nbsp;:
<%= pagination_links_remote @user_pages %>
<% end %>
