title: Magento: getAttributeText('manufacturer') doesn't work
body: <p>I would very much appreciate your help. I am new to Magento and exploring it's possibilities. I have this piece of code, which loads products from category and their attributes:</p>
  
  <pre><code>&lt;?php
      $_productCollection=$this-&gt;getLoadedProductCollection();
      $_helper = $this-&gt;helper('catalog/output');
  ?&gt;
  
  &lt;?php if(!$_productCollection-&gt;count()): ?&gt;
  &lt;p class="note-msg"&gt;&lt;?php echo $this-&gt;__('There are no products matching the selection.') ?&gt;&lt;/p&gt;
  &lt;?php else: ?&gt;
  &lt;div class="category-products"&gt;
       &lt;?php // Grid Mode ?&gt;
      &lt;?php $_collectionSize = $_productCollection-&gt;count() ?&gt;
      &lt;?php $_columnCount = $this-&gt;getColumnCount(); ?&gt;
          &lt;?php $_iterator = 0; ?&gt;
          &lt;ul class="products-grid"&gt;    
          &lt;?php $i=0; foreach ($_productCollection as $_product): ?&gt;
              &lt;li class="item"&gt;
                  &lt;a href="&lt;?php echo $_product-&gt;getProductUrl() ?&gt;" title="&lt;?php echo $this-&gt;stripTags($this-&gt;getImageLabel($_product, 'small_image'), null, true) ?&gt;" class="product-image"&gt;&lt;img src="&lt;?php echo $this-&gt;helper('catalog/image')-&gt;init($_product, 'small_image')-&gt;resize(252); ?&gt;" width="252" height="252" alt="&lt;?php echo $this-&gt;stripTags($this-&gt;getImageLabel($_product, 'small_image'), null, true) ?&gt;" /&gt;&lt;/a&gt;
                  &lt;h3 class="product-name"&gt;&lt;a href="&lt;?php echo $_product-&gt;getProductUrl() ?&gt;" title="&lt;?php echo $this-&gt;stripTags($_product-&gt;getName(), null, true) ?&gt;"&gt;&lt;?php echo $_helper-&gt;productAttribute($_product, $_product-&gt;getName(), 'name') ?&gt;&lt;/a&gt;&lt;/h3&gt;
                  &lt;h4 class="product-name"&gt;&lt;?php echo $_product-&gt;getAttributeText('manufacturer') ?&gt;&lt;/h4&gt;                
                  &lt;?php echo $this-&gt;getPriceHtml($_product, true) ?&gt;
               &lt;/li&gt;  
          &lt;?php endforeach ?&gt;
          &lt;/ul&gt;
          &lt;script type="text/javascript"&gt;decorateGeneric($$('ul.products-grid'), ['odd','even','first','last'])&lt;/script&gt;
  &lt;/div&gt;
  &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>My question is: why "echo $_product->getAttributeText('manufacturer')" is not working here? I have tried countless variants with different code, but the manufacturer parameter just doesn't show up. Do you know why?</p>
