Body
When the layout rendering code encounters this <pre><code><block type="layout/carousel" name="featured_carousel"> </code></pre> It immediately instantiates the block. That means the block's <code> __construct</code> method is called before your <code>setData</code> method is called. So, at the time of construction, no data has been set, which is why your calls to <code>var_dump</code> return an empty array. Also, immediately after being created, the block is added to the layout <pre><code>#File: app/code/core/Mage/Core/Model/Layout.php ... $block->setLayout($this); ... </code></pre> When this happens, the block's <code>_prepareLayout</code> method is called. <pre><code>#File: app/code/core/Mage/Core/Block/Abstract.php public function setLayout(Mage_Core_Model_Layout $layout) { $this->_layout = $layout; Mage::dispatchEvent('core_block_abstract_prepare_layout_before', array('block' => $this)); $this->_prepareLayout(); Mage::dispatchEvent('core_block_abstract_prepare_layout_after', array('block' => $this)); return $this; } </code></pre> So, this means that any data set in your layout update xml is still not available, even in <code>_prepareLayout</code>. Once the system is done creating the block, it moves on to the next XML node. <pre><code><action method="setData"> <name>filter_attribute</name> <value>is_featured_product</value> </action> </code></pre> and calls the <code>setData</code> method. Now your block has its data set. Try defining a <code>_beforeToHtml</code> method on your block and checking for data there. (Assuming your block is being rendered)

1. COWow, fantastic answer. Defining a `_beforeToHtml` did the trick and will work for my use case perfectly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
