title: Magento - registry and current category
body: <p>I have a question about <code>Mage::registry</code> and <code>categories:</code> I'm a on a category page, I retrieve current category by <code>Mage::registry('current_category')</code>. I've noticed that it works only for root categories, in fact if I visit a subcategory page I retrieve always the root category with <code>Mage::registry('current_category')</code>. So the question is: is something about backend configuration, cache or something else?</p>
