collection_select doesn't select current choice

Hi everybody,

I've discovered a problem when using collection_select in a user registration form:

f.collection_select(:province_id, Province.find(:all), :id, :name,
                  {:prompt   => "Select a Province"})

The problem is, that later on in options_for_select the selected value is still available, but as a String object and not like the id as FixNum.

For now I'm using a stupid workaround like:

selected_attribute = ' selected="selected"' if option_value_selected?(value.to_s, selected)

Anyway I'd like to hear a statement from the developers - am I using the helper in a wrong way?!

I tried using it with Rails 2.0.2 and 2.1.1

Thank you so much!

Best regards, Florian
