title: Zend Navigation (breadcrumbs) not displaying
body: <p>I'm having a problem displaying breadcrumbs with Zend_Navigation.</p>
  
  <p>I have a single controller that takes in a parameter to query out articles from the DB. So, if you point to "articles/view/id/3", it returns the article with an id of 3. The problem I'm having is having breadcrumbs work under this logic. Ideally, when going to "articles/view/id/3" I'd like the breadcrumbs to be: "Articles > Article_Name" </p>
  
  <p>My code renders the navigation and sub navigation alright, it just fails on the breadcrumbs, currently not displaying anything.</p>
  
  <p>Here's my code:</p>
  
  <p>1) Site's navigation in an XML format that looks like:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;zend-config xmlns:zf="http://framework.zend.com/xml/zend-config-xml/1.0/"&gt;
    &lt;nav&gt;
      &lt;articles&gt;
        &lt;label&gt;Articles&lt;/label&gt;
        &lt;uri&gt;/&lt;/uri&gt;
        &lt;order&gt;1&lt;/order&gt;
        &lt;active&gt;1&lt;/active&gt;
        &lt;visible&gt;1&lt;/visible&gt;
        &lt;pages&gt;
          &lt;article_one&gt;
            &lt;label&gt;Article One&lt;/label&gt;
            &lt;uri&gt;/articles/view/id/81e728d9d4c2f636f067f89cc14862c&lt;/uri&gt;
            &lt;order&gt;1&lt;/order&gt;
            &lt;active&gt;1&lt;/active&gt;
            &lt;visible&gt;1&lt;/visible&gt;
          &lt;/article_one&gt;
        &lt;/pages&gt;
      &lt;/articles&gt;
    &lt;/nav&gt;
  &lt;/zend-config&gt;
  </code></pre>
  
  <p>2) Navigation (In the layout):</p>
  
  <pre><code>$config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml', 'nav');
  $nav = new Zend_Navigation($config);
  $view = new Zend_View();
  $view-&gt;navigation($nav);
  echo $view-&gt;navigation()-&gt;menu();
  </code></pre>
  
  <p>3) Breadcrumbs (in the Articles controller):</p>
  
  <pre><code>public function init() {
          $uri = $this-&gt;_request-&gt;getPathInfo();
          $activeNav = $this-&gt;view-&gt;navigation()-&gt;findByUri($uri);
          $activeNav-&gt;class = "selected";
          $activeNav-&gt;active = true;
      }
  </code></pre>
  
  <p>4) Breadcrumbs (In the layout):</p>
  
  <pre><code>//Doesn't display anything[/B]
  echo $view-&gt;navigation()-&gt;breadcrumbs()-&gt;setLinkLast(true);
  </code></pre>
  
  <p>Thanks in advance for any help!</p>
