File dictating how simple products display on product page

Question

Was wondering if anyone could point me in the direction of the .phtml file that dictates how simple products are displayed on their parent configurable product pages?

I am running into an issue where the simple product and attributes (images / sku / etc) for these products that are out of stock are being removed from the configurable product page.

Looking at the 'configurable.phtml' file I cannot seem to find where this is.

Any help would be greatly appreciated!

Thanks!

When loading all the allowed products attached to a configurable product the following code is called:

/**
 * Get Allowed Products
 *
 * @return array
 */
public function getAllowProducts()
{
    if (!$this->hasAllowProducts()) {
        $products = array();
        $skipSaleableCheck = Mage::helper('catalog/product')->getSkipSaleableCheck();
        $allProducts = $this->getProduct()->getTypeInstance(true)
            ->getUsedProducts(null, $this->getProduct());
        foreach ($allProducts as $product) {
            if ($product->isSaleable() || $skipSaleableCheck) {
                $products[] = $product;
            }
        }
        $this->setAllowProducts($products);
    }
    return $this->getData('allow_products');
}

The key that you are looking for is the line if ($product->isSaleable() || $skipSaleableCheck) { this will only allow the addition of saleable products unless overridden.

One option for you is to listen to the event catalog_product_is_salable_after and override the value of is_salable, note that there is a typo in Magento not my regarding saleable.
