zend framework - Zend_Form not showing error message -

i have following zf form element.

    $this->addelement('text', 'price', array(         'required'  => true,         'label'     => 'price:',         'attribs'   => array(             'title'     => 'please enter value of artwork'),         'filters'   => array('currency'),         'validators'    => array(             array('notempty', true, array(                 'messages' => array(                     zend_validate_notempty::is_empty =>                         "you must enter artworks price"))),             array('float', true, array(                 'messages'  => array(                     zend_validate_float::invalid =>                          "you must enter valid price",                     zend_validate_float::not_float =>                         "you must enter valid price"))),             array('greaterthan', true, array(                 'min'   => 0.99,                 'messages'  => array(                     zend_validate_greaterthan::not_greater =>                         "you must enter value of £1.00 or more"))))     )); 

the last validator zend_validate_greaterthan has been set error message, problem error message not displayed on form when validator fails. rendered empty unordered list!!

<ul>     <li></li> </ul> 

when check messages output zend_form error , message.

array(1) {   ["price"]=>   array(1) {     ["notgreaterthan"]=>     string(39) "you must enter value of £1.00 or more"   } } 

does know why message not being rendered on form?

many in advance

edit

the decorator using viewscript render form, on form have.

$this->setdecorators(array(     array('viewscript', array('viewscript' => 'forms/add-item.phtml')) )); 

and viewscript itself.

$attribfilterobj = new freedom_zend_filter_htmlattribs(); $attribs = $attribfilterobj->filter($this->element->getattribs()); ?> <form <?php echo $attribs; ?>> <dl>     <?php echo $this->element->artworktitle->title->render(); ?>     <?php echo $this->element->artworkdescription->description->render(); ?>     <?php echo $this->element->price->render(); ?>     <?php echo $this->element->genres->render(); ?>     <?php echo $this->element->image->render(); ?>     <?php echo $this->element->add->render(); ?> </dl> </form> 

edit

the output of var_dump follows

this caused forgetting include 'errors' in form decorator element. if you're using custom decorator, check first.
