this is the decorator code

$mydecorate = array( 
      'ViewHelper', 
      array('Errors', array('placement' => 'append','class' => 'error')),
      array('Label', array('separator' => '')),
      array('HtmlTag', array('tag' => 'p', 'class' => 'element-form'))
      );

html result of two input elements with the above decorator:

<p class="element-form">
    <label for="firstname" class="required">First Name:</label>
    <input name="firstname" id="firstname" value="" type="text">
</p><ul class="error"><li>required field!</li></ul>
<p class="element-form">
    <label for="lastname" class="required">Last Name:</label>
    <input name="lastname" id="lastname" value=""  type="text">
</p><ul class="error"><li>required field!</li></ul>

I'd like the error message to be placed inside the p.element-form tag, any idea pleas?

thanks
