title: Unable to get product custom attribute value on product page
body: <p>I introduced an attribute for products from admin, and assigned a value to it for a specific product to get it's value. But the value is not showing up on frontend, I tried all recommended methods but was unable to get it. Then I moved on it's debugging with <code>print_r($_product-&gt;debug())</code>. And this debug showed me the following behavior:</p>
  
  <pre><code>Array
  (
      [store_id] =&gt; 1
      [entity_id] =&gt; 339
  
      [_cache_instance_products] =&gt; Array
      (
          [0 (Mage_Catalog_Model_Product)] =&gt; Array
          .
          .
          .
          [419 (Mage_Catalog_Model_Product)] =&gt; Array
          (
              [entity_id] =&gt; 1210
          [entity_type_id] =&gt; 4
              [prd_help_tab] =&gt; This is testing help for "Mobster US e-liquid"
          )
      )
  )
  </code></pre>
  
  <p>The attribute name is "prd_help_tab" and  it's value is there, but it's inside _cache_instance_products => 419 (Mage_Catalog_Model_Product) => prd_help_tab</p>
  
  <p>My question is how to get this value in template file? As the value is only in hierarchy which mentioned above. </p>
  
  <p>After further investigations, I came to know that this problem raises up in "Configurable Products". </p>
