title: Zend and jQuery DatePicker producing unexpected result
body: <p>I have a Zend form, for which I have enabled jQuery components via:</p>
  
  <pre><code>ZendX_JQuery::enableForm($this);
  </code></pre>
  
  <p>and then added several non-jQuery elements, and one jQuery DatePicker, defined as:</p>
  
  <pre><code>$testing = new ZendX_JQuery_Form_Element_DatePicker('dp1', array('jQueryParams' =&gt; array('dateFormat' =&gt; 'yy-mm-dd')));
  $testing-&gt;setLabel('Date of Birth 2')
      -&gt;setRequired(true)
      -&gt;addValidator('NotEmpty');
  </code></pre>
  
  <p>I then set up the Decorators as follows (first for all the elements, and then replaced the Decorator definition for the DatePicker):</p>
  
  <pre><code>$this-&gt;clearDecorators();
  $this-&gt;addDecorator('FormElements')
      -&gt;addDecorator('HtmlTag', array('tag' =&gt; 'div', 'class'=&gt;'form-block'))
      -&gt;addDecorator('Form');
  
  $this-&gt;setElementDecorators(array(
      array('ViewHelper'),
      array('Errors'),
      array('Description', array('tag' =&gt; 'div', 'class' =&gt; 'tooltip')),
      array('Label', array('separator'=&gt;' ')),
      array('HtmlTag', array('tag' =&gt; 'div', 'class'=&gt;'element-block')),
  ));
  
  $formJQueryElements = array(
      array('UiWidgetElement', array('tag' =&gt; '')),
      array('Errors'),
      array('Description', array('tag' =&gt; 'div', 'class' =&gt; 'tooltip')),
      array('Label', array('separator' =&gt; ' ')),
      array('HtmlTag', array('tag' =&gt; 'div', 'class' =&gt; 'element-block')),
  );
  $this-&gt;getElement('dp1')-&gt;clearDecorators();
  $this-&gt;getElement('dp1')-&gt;setDecorators($formJQueryElements);
  </code></pre>
  
  <p>This seems to display all my fields correctly, with the exception of the DatePicker, which has somehow been converted into a text field. The HTML for the field looks like:</p>
  
  <pre><code>&lt;div class="element-block"&gt;
      &lt;label for="dp1" class="required"&gt;Date of Birth 2&lt;/label&gt; 
      &lt;input type="text" name="dp1" id="dp1" value=""&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>which is not a DatePicker. What have I missed in setting this up, or what error have I made here?</p>
  
  <p>Many thanks.</p>
