will_paginate + RJS error

Hi there!
I need some help, I'm new to rjs + will_paginate and don't know how
to
solve this problem.
The application apparently is working fine, the partial is rendered
by the javascript, the pagination works fine, but sometimes, when I
hit the next page number or " next >>", it reders the code below.
Im using rails 2.3.8, ruby 1.8.7. and will_paginate 2.3.15
Thanks!
try { Element.update("search_professors", "

My Controller:
def search_professors
  begin
   @professors =
User.search_for(params[:search]).paginate(:all,:conditions =>
{:professor => true},:page => params[:page], :per_page => 8)
  rescue => e
   flash[:error] = e.to_s
   @professors= User.search_for '*'
  end
   respond_to do |format|
      format.html
      format.js
    end
end
The view:
  <% tabnav :user do%>
  <% form_remote_tag :url => 'search_professors' do %>
      <%= text_field_tag :search, params[:search], :value => nil %>
      <%= submit_tag "Go", :name => nil , :disable_with => "Please
wait..."%>
  <%end%>
  <div id="search_professors">
      <%= render :partial => "course/professors_list" %>
  </div>
  <br/>
  <% end %>
The partial inside the view:
<h1> Professors List</h1>
<% form_tag('/user/email_professors', :method => :post) do%>
<% if !...@professors.empty? %>
    <table class="course" id="mats">
       <tr class="header">
            <th></th> <th>Name</th> <th>Address</th> <th>Action</th>
       </tr>
          <% @professors.each do |professor| %>
            <tr class="<%= cycle('odd', 'even') %>">
                 <% if !professor.nil? %>
                      <td width="5%" > <%= check_box_tag
"user_emails[]" , professor.email %> </td>
                 <% end %>
                 <td><%=image_tag professor.photo.url(:mini) %></

                 <td width="40%"> <%= professor.spec.full_name %></

                 <td width="40%"> <%= professor.address.address %>
</

            </tr>
        <% end %>
     </table>
  <% else %>
       <br></br>
       <h4><i>No results!</i></h4>
       <br></br>
  <% end %>
<% end %>
   <div style="font-size: small">
        <%= will_paginate @professors %>
   </div>
My JavaScript file
search_professors.rjs
page.replace_html :search_professors, :partial => "course/
professors_lista", :object => @users
