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 %\>

 \<%= render :partial =\> 'index' -%\>

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