Zend_Form_Element_File (no decorator found error) - zend-framework

Question

I am creating a form with an upload element. I have created the file element with the code below
$image = new Zend_Form_Element_File('image');
$image->setAttrib('title','Listing Image:')
->addDecorator('File')
->addValidator('Size', false, 204800)
->addValidator('Extension', false, 'jpg,png,gif');
$this->addElement($image);
Which as far as I can tell works fine. It tries to add a file element to the page. I get an error which says " Warning: No file decorator found... unable to render file element in..."
As you can see I have set the decorator for the element to be the File decorator so I am unsure why I am getting this error?
It is worth noting I have removed all default decorators except for viewHelper and PrepareElements and I am using a view partial as the viewHelper to display the output. Just incase this is required I have also included that below.
<form method="<?php echo $this->element->getMethod(); ?>" action="<?php echo $this->element->getAction(); ?>">
<div class="boxmiddle-Holder">
<div class="boxmiddle-content">
<table border="0" cellspacing="2" cellpadding="3" class="dataTable">
<?php foreach($this->element->getElements() as $element): ?>
<!-- if not a button then display label -->
<tr>
<td><label for="<?php echo $element->getName(); ?>"><?php echo $element->getAttrib('title'); ?></label></td>
<td class="normal"><?php echo $element; ?></td>
<?php if($element->getMessages()) {
foreach($element->getMessages() as $message) { ?>
<td> <?php echo "<p class='elementError'>".$message."</p>"; ?></td>
<?php }
}
?>
</tr>
<?php endforeach; ?>
</table>
</div>
</div>
Any ideas?

I'd double check to make sure the File decorator isn't being cleared or reset later, that error indicates that your form's file element does not have a Zend_Form_Decorator_File decorator attached to it.
Look in Zend/Form/Element/File.php around line 859 for the function that throws this error. I suspect somehow the File decorator is being removed from the element. It could be that it has no decorators or is just lacking the File decorator.
Hope that helps.
