date_select validation of a invalid date

Hi,

What I'm asking might be simple for some of you but I'm trying to fix this for two days and I just can't figure out how to make this thing work. I have a model with a date_select validation that is working just fine except when I fill the form with a invalid date like Feb 30 1989. I thought the plugin validates_multiparameter_assignments would catch this kind of invalid date but for some reason is just not working. Below I'm pasting my model and controller code to see if someone can help me.

class Spec < ActiveRecord::Base

  belongs_to :user

  ALL_FIELDS = %w(first_name last_name address phone gender birthdate city state zip_code)   STRING_FIELDS = %w(first_name last_name address phone city state)   VALID_GENDERS = ["Male", "Female"]   START_YEAR = 1900   END_YEAR = Date.today.year - 18   ZIP_CODE_LENGTH = 10

  validates_length_of STRING_FIELDS, :maximum => DB_STRING_MAX_LENGTH   validates_inclusion_of :gender, :in => VALID_GENDERS, :allow_nil => true, :message => "must be male or female"   validates_presence_of :zip_code, :birthdate   validates_multiparameter_assignments :message => " is not a valid date."   validates_each :birthdate do |record, attr, value|         record.errors.add attr, "is not a valid date. You must be at least 18 years old to sign in." if value > Date.new((Date.today.year - 18),(Date.today.month),(Date.today.day))     end end

class SpecController < ApplicationController

  before_filter :protect

  # Edit the user's spec.   def edit       @user = User.find(session[:user_id])       @title = "aykal - edit #{@user.screen_name} profile"       @user.spec ||= Spec.new       @spec = @user.spec       if param_posted?(:spec)         @user.spec.valid?           if @user.spec.update_attributes(params[:spec])             flash[:notice] = "Changes saved."             redirect_to :controller => "user", :action => "index"           end       end     end

end

Thanks, Thiago Guerra

Oh, I forgot to send the error msg I'm getting and I also double checked and it is not working with any date I try. It is not just with the invalid ones...

NoMethodError in SpecController#edit

You have a nil object when you didn't expect it! The error occurred while evaluating nil.>

What I don't get is that birthdate is not nil...
