title: Magento : How to convert quote item attribute to order item attribute
body: <p>I've added a quote item attribute and an order item attribute (and invoice and shipment) called "parent_info":</p>
  
  <pre><code>$installer-&gt;addAttribute("quote_item", "parent_info", array("type"=&gt;"varchar"));
  $installer-&gt;addAttribute("order_item", "parent_info", array("type"=&gt;"varchar"));
  $installer-&gt;addAttribute("invoice_item", "parent_info", array("type"=&gt;"varchar"));
  $installer-&gt;addAttribute("shipment_item", "parent_info", array("type"=&gt;"varchar"));
  </code></pre>
  
  <p>I was able to save the user input to the quote item, but I can't convert it to the order item.
  I've tried to add this code under global in my config file:</p>
  
  <pre><code>    &lt;fieldsets&gt;
          &lt;sales_convert_quote_item&gt;
              &lt;parent_info&gt;
                  &lt;to_order_item&gt;*&lt;/to_order_item&gt;
                  &lt;to_invoice_item&gt;*&lt;/to_invoice_item&gt;
                  &lt;to_shipment_item&gt;*&lt;/to_shipment_item&gt;
              &lt;/parent_info&gt;
          &lt;/sales_convert_quote_item&gt;
      &lt;/fieldsets&gt;
  </code></pre>
  
  <p>but when I moved to checkout nothing happened</p>
  
  <p>I've also tried to add an observer:</p>
  
  <pre><code>&lt;sales_convert_quote_item_to_order_item&gt;
              &lt;observers&gt;
                  &lt;extra_options&gt;
                      &lt;type&gt;model&lt;/type&gt;
                      &lt;class&gt;test/observer&lt;/class&gt;
                      &lt;method&gt;onSalesConvertQuoteItemToOrderItem&lt;/method&gt;
                  &lt;/extra_options&gt;
              &lt;/observers&gt;
          &lt;/sales_convert_quote_item_to_order_item&gt;
  </code></pre>
  
  <p>But it doesn't get called (I've added a log to the observer method).</p>
  
  <p>What can be the problem? Can it be because I use an extension for the checkout (gomage lightcheckout)?</p>
