title: Magento - Custom attribute in customer address, not copied to sales_flat_order_address and sales_flat_quote_address on checkout
body: <p>I have created a new attribute ‘county’ in customer address. It is working fine and I am able to save values in this field from the frontend.</p>
  
  <p>I want this field available in address of orders. 
  So I have added a column ‘county’ in the tables </p>
  
  <blockquote>
    <p>‘sales_flat_quote_address’ and ‘sales_flat_order_address’</p>
  </blockquote>
  
  <p>Then I have modified Sales/etc/config.xml to include this field in fieldsets. I have added entries for this field in </p>
  
  <blockquote>
    <p>sales_copy_order_billing_address,<br>
     sales_copy_order_shipping_address,<br>
     sales_convert_quote_address,<br>
     sales_convert_order_address,<br>
    customer_address  </p>
  </blockquote>
  
  <p>But when I do onepage checkout, the value in this field is not copied to the address in orders. I am selecting an existing address with value in this field during checkout for billing and shipping address.</p>
  
  <p>Right now, I have not edited any template file in checkout to include this field. But as I am selecting an existing address, this shouldn’t be causing the problem, right ?</p>
  
  <p>I am using magento 1.5.1.0. While I know php well, I am kind of a newbie in magento.</p>
  
  <p>I have checked the question <a href="https://stackoverflow.com/questions/5609987/magento-save-custom-address-attribute-in-checkout">Magento: save custom address attribute in checkout</a> and have done everything as given in the answer.</p>
  
  <p>Have I missed out something. If so, please provide your suggestion. 
  Thanks.</p>
