title: Get simple products belonging to configurable product AFTER configurable product save
body: <p>In magento, it is possible to get the simple products associated to a configurable product by using the following call:</p>
  
  <pre><code>$childProducts = Mage::getModel('catalog/product_type_configurable')-&gt;getUsedProducts(null, $product);
  </code></pre>
  
  <p>I am trying to call this function after the configurable product is saved, so that I can get the new list of simple products it uses. So I am making the above call from a method that is triggered by the <code>catalog_product_save_after</code> event. However, after the call <code>$childProducts</code> stores the simple products that were associated to <code>$product</code> BEFORE the save operation, not AFTER it.</p>
  
  <p>How could I get the simple products associated to <code>$product</code> after the save operation?</p>
  
  <p>Thanks in advance, any suggestion is appreciated.</p>
