params[:id] not working right?

something very odd is going on, when I put in the url
http://mysite/blabla/bla/21
it will only see the 2 and ignore the 1 instead of getting the full id "21"
obviously this is causing a lot of issues in my application.. I am looking and looking and cant find whats going on..
any ideas what im doing wrong? I have look all over..
here is some code snips

def roster
                @authreg_in = session[:authreg]
                @name = Authreg.find(params[:id])
                name2 = (@name.username + "@" + @name.realm)
                @amigos = Rosteritems.find( :all, :conditions => { :"collection-owner" => "#{name2}" })
   end

<%= @name.id %> <!-- this is to debug ->
<%= @authreg_in %> <!-- this is to debug ->
<% if @name.id == @authreg_in || @authreg_in == 1 %>

<table id="authregs">
  <tr>
    <th>JID</th>
  </tr>
<% @amigos.each_index do |amigo| %>
        <tr class="<%= cycle('odd', 'even') -%>">
        <td><%= @amigos[amigo].jid %></td>
        </tr>
        <% end %>
</table>
<% else %>
        <p>you are trying to see someones elses roster!!!<p>
<% end %>

here is more info from the log as you can see the url has 11 and the ID only gets 1

Parameters: {"format"=>"1", "action"=>"roster", "id"=>"1", "controller"=>"rosteritems"}
Completed in 0.00100 (999 reqs/sec) | Rendering: 0.00015 (14%) | DB: 0.00000 (0%) | 406 Not Acceptable [http://xxxxxxxx.info/rosteritems/roster/11]

What is fomat =>1 ? is the first time I see it.. this may be the cause..?

Have you got something interesting in your routes.rb ? (the format
parameter is usually there so that you can link to foo.xml which
provides the xml representation of foo, or one that will provide json
etc...)
