Rails - Jul 2013 - Multiple select issue with a HABTM relationship using Rails 4

Although the code seems to be right, when I try to send the form, the 
values of the multiple select aren''t being sent.If I just remove the 
multiple option, everything works as expected considering just one value, 
but it''s important to store more than one tag per transaction.

Do you have any ideas about what could be happening here?

*Model*

*Transaction.rb*

class Transaction < ActiveRecord::Base
    has_and_belongs_to_many :tags

*Tag.rb*

class tag < ActiveRecord::Base
    has_and_belongs_to_many :transactions

*View*

<%= form.collection_select :tag_ids, @tags, :id, :name, {}, 
    {:multiple => true} %>

*Result:*

<select id="transaction_tag_ids" multiple="multiple"
name="transaction[tag_ids][]">
    <option value="1">..</option>
</select>

Are you sure about that? Check the log output from submitting the
form.
