title: Facebook Feed Dialog Mobile Url: Issue with display=wap
body: <p>I am using this url to direct my mobile web page to a facebook wall post dialog page, however I can't seem to get <code>display=wap</code> to work. </p>
  
  <pre><code>http://m.facebook.com/dialog/feed?app_id=&lt;myappId&gt;&amp;redirect_uri=&lt;myRedirectUri&gt;&amp;link=&lt;myLink&gt;&amp;display=&lt;wap|touch&gt;&amp;picture=&lt;myPicture&gt;&amp;caption=&lt;myCaption&gt;&amp;description=&lt;myDescription&gt;&amp;name=&lt;myName&gt;
  </code></pre>
  
  <p>Using <code>display=touch</code> works fine on most devices except some blackberries I've tested, where the dialog page is blank except for the "Publish" and "Cancel" buttons. When I use <code>display=wap</code>, I get "An error has occured" no matter what I do.</p>
  
  <p>Does facebook support this feed dialog with display=wap? I found this url on their developer's web page here:
  <a href="http://developers.facebook.com/docs/reference/dialogs/" rel="nofollow">Facebook Dialogs</a>
  Under the heading labeled : <strong>Mobile Display Modes</strong></p>
  
  <p>I'd appreciate any advice!</p>
