Css selectors and ActionView::FormHelper

Rails 2.2.2

In a view partial, When I do this:

  <%= label client_detail.class.to_s.downcase,
            :client_credit_limit,
            "Credit Limit: ",
            :class => :input_box_label,
            :for => 'input_client_credit_limit
  -%>

  <%= ff.text_field  :client_credit_limit,
        :id => 'input_client_credit_limit',
        :size => 12,
        :value => client_detail.client_credit_limit
  -%>
</p>

Then I see this:

  <label class="input_box_label"
     for="input_client_credit_limit">
     Credit Limit:
  </label>

  <input
     id="input_client_credit_limit"
     name="client[client_credit_limit]"
     size="12" type="text" value="0" />

But, when I do this:

<%= label :client,
          :client_credit_policy,
          "Credit Policy",
          :class => :input_box_label
-%>

<%= ff.select :client_credit_policy,
          [ ['CASH - Advance Billing', 'CASH'],
            ['OPEN - Open Account', 'OPEN'],
          ],
          :prompt => 'Select Credit Policy Code',
          :size => 4
-%>

Then I see this:

<label
  class="input_box_label"
  for="select_client_credit_policy">
  Credit Policy
</label>

<select
   id="client_client_credit_policy"
   name="client[client_credit_policy]">
   <option value="CASH" selected="selected">
      CASH - Advance Billing</option>
   <option value="OPEN">
      OPEN - Open Account</option>
</select>

Select does not honour the :id => ‘text’ option when provided. Instead
it creates an id of the form _. However, text_field
does honour the :id => ‘text’ option if given.

Is this a bug?
