title: Windows phone page not reloading
body: <p>I have a detail page that gets a static item </p>
  
  <pre><code> public static Article sharedArticle; 
  </code></pre>
  
  <p>When i first load the page using </p>
  
  <pre><code> SharedInformation.sharedArticle = (Article)lstOffline.SelectedItem;
  Frame.Navigate(typeof(DetailsArticle));
  </code></pre>
  
  <p>However when i try to reload it from the previous Page after changing the value of <code>sharedArticle</code> I keep getting the same Page of <code>DetailsArticle</code> loaded with the old item.
  How can I disallocate <code>DetailsArticle</code> after navigating to another page?</p>
