3 Slate View Pattern For Zend Framework

<!-- Wrapper for a slate -->
<div id="<?=$this->id ?>" class="<?=$this->slate ?> slate-wrapper">
	<?=$this->content?>	
<div>

<!-- 3 Slate List View -->
<? if ($this->slate == Kfx2_View_Helper_ThreeSlate::SLATE_BLANK ) : ?>

<? elseif ($this->slate == Kfx2_View_Helper_ThreeSlate::SLATE_ERROR) :?>

<? elseif ($this->slate == Kfx2_View_Helper_ThreeSlate::SLATE_REGULAR) :?>
	
<? endif;?>

<!-- SET SLATE IN CONTROLLER -->
<?php
	public function listAction()
	{
		$materials = $this->_Material->getTable()->findAll(); 
		$this->view->slate = $materials->count() == 0 ? 
			Kfx2_View_Helper_ThreeSlate::SLATE_BLANK : Kfx2_View_Helper_ThreeSlate::SLATE_REGULAR;
	}
 
?>

I think this might have been better decided by using an action helper to route to a different view based on the state ... this is old and was only a concept.
