title: Extbase FAL file download
body: <p>I have question about file download with Extbase and FAL.
  I can render image with </p>
  
  <pre><code>&lt;f:image src="{file.uid}" alt="" width='100' height="100" treatIdAsReference="1"/&gt; 
  </code></pre>
  
  <p>I can get image, but I also have PDF file for download, and I can't use this ViewHelper. 
  Is there any other ViewHelper for file downloads?
  If i dump that file i get this:</p>
  
  <pre><code>file =&gt; TYPO3\CMS\Extbase\Domain\Model\FileReferenceprototypepersistent entity (uid=1342, pid=310)
           originalResource =&gt; NULL
           uid =&gt; 1342 (integer)
           _localizedUid =&gt; 1342 (integer)modified
           _languageUid =&gt; 0 (integer)modified
           pid =&gt; 310 (integer)
  </code></pre>
  
  <p>originalResource  is null for file, and for image, image is printed with that ViewHelper. And I can't get file...</p>
  
  <p>Any help is welcome... </p>
