select helper still the worth thing in rails...

I have been trying all the day to make it happen, initial display is fine , but I cannot redisplay the selected value once the choice is done in my select helper

I setup my slector in a helper (need to include the first option 'all', as a prompt is displayed only once.... in my partial def company_role_selection(selection=nil)      roles= [['all', 0]]     roles += company_roles.collect {|h| [ h.name, company_roles.index(h)]}.compact.uniq     select('role', 'id', roles, {:selected => selection} ,{:onchange => "$('select_role').submit()"}) end

in my controller, I get the selection @selection = params[:role][:id]

then I find and display the users...

and I redisplay the page with the form and the list

<% form_for(:user, :url => user_path(@user), :html => {:method => :get, :id => 'select_role' }) do |f| %>   <%= render :partial => 'select_role' , :locals=>{:selection => @selection } -%> <% end %>

<div id="hits" >   <%= render :partial => 'index' -%> </div>

in my controller, I get the selection @selection = params[:role][:id]

You probably need to convert that to an integer (since '1' != 1)
