title: zend form decorators
body: <p>Having (more) issues with zend form decorators. I've got this so far:</p>
  
  <p>Reset overall form decorator:</p>
  
  <pre><code>    $this-&gt;clearDecorators();
      $this-&gt;setDecorators(array('FormElements', 'Form'));
  </code></pre>
  
  <p>I'm adding all my elements to a display group that i want to be inside a fieldset, within a DL</p>
  
  <pre><code>    $group-&gt;setDecorators(array(
             'FormElements',
              array('HtmlTag', array('tag' =&gt; 'dl')),
             'Fieldset'
      ));   
  </code></pre>
  
  <p>all working so far, now i want to place an image tag immediately before the fieldset. on its own this would work:</p>
  
  <pre><code>        $group-&gt;setDecorators(array(
              'FormElements',
              'Fieldset',
              array('HtmlTag',array('tag'=&gt;'img','placement'=&gt;'prepend','src'=&gt;'/images/'.$imgs[$i-1]-&gt;im_name.'_main.jpg'))
          ));   
  </code></pre>
  
  <p>but this doesnt (it stops the DL being added inside the fieldset):</p>
  
  <pre><code>        $group-&gt;setDecorators(array(
              'FormElements',
              array('HtmlTag', array('tag' =&gt; 'dl')),
              'Fieldset',
              array('HtmlTag',array('tag'=&gt;'img','placement'=&gt;'prepend','src'=&gt;'/images/'.$imgs[$i-1]-&gt;im_name.'_main.jpg'))
          ));
  </code></pre>
  
  <p>Where am i going wrong?</p>
