I have the following line

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

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](http://wiki.rubyonrails.org/rails/pages/HowtoUseFormOptionHelpers).

Can anyone help me make the current selected items get the

`selected="selected"` tag.
