Rails - Sep 2008 - collection_select reseting selection whenever page refreshes

I have a collection_select dialog that I have for selecting Users on a
page.  I am wanting the selection to remember and display the last
selected user from the database.  Every time I refresh the page it is
going back to its default value even though the data has changed.  Is
there a way to tell it to take the data that appears in the database
and not reset the selection tag like it a new value.

Here is my code that I''m using.
 <% @users = User.list_all_testers %>
 <%= collection_select(:machine, :user_id, @users, :id, :fullname,
options = {:include_blank=>true}, html_options = {:onChange =>
remote_function(:update => "ajaxmessage", :url => {:action =>
''update_machine_user'',
            :controller =>
''manage_machines'',:id=>machine.id},:with=>"''users_id=''+this.value")})
%>

Thanks William

I assume you have the Ajax and the update parts right.  It is a
question of populating the right value into @machine.

This is NOT working. See 
http://rails.lighthouseapp.com/projects/8994/tickets/1138-collection_select-doesnt-select-current-choice
for details.
Id is a FixNum value while the selected value is transfered as a String 
value.

So value and selected can never be the same in option_value_selected? If 
value is FixNum!
