selected items in a multiple select

rubyonrails-talk

I have the following line

[code]<%= collection_select_with_current("permissions", :permission, Permission.find(:all, :order => "name"), :id, :short, @page.permissions, {:multiple => true}) %></label></p>[/code]

This generates a selectbox, with multipleselect enabled. It posts correctly, but it does not mark the selected ones as I had hoped it would. The code is originally from http://wiki.rubyonrails.org/rails/pages/HowtoUseFormOptionHelpers.

Can anyone help me make the current selected items get the [code]selected="selected"[/code] tag.

<% @all_permissions = Permission.find(:all, :order => “name”) %>

<% @selected = @page.permissions.collect { |p| p.id } %>
