What is the best way to get an ecommerce product attribute value by handle?

In case anyone is wondering, here was the solution:

$myAttributeKey = CoreCommerceProductAttributeKey::getByHandle('myAttributeHandle');
$myAttributeValueObject = $product->getAttributeValueObject($myAttributeKey);
$attributeValue = $myAttributeValueObject->getValue();

I get this error, even though the product attribute exists and the handle is correct:

Fatal error: Call to a member function getAttributeValueObject() on a non-object

....yes, because the 3rd line:
$myAttributeValueObject = $product->getAttributeValueObject($myAttribute);

is incorrect - or, doesn't show the variable "$product" as being an instance of the CoreCommerceProductAttributeKey class (which might have happened early in jgarcia's code). So (your) PHP doesn't know where to look for the getAttributeValueObject method. Solve that problem and you'll be good to go.

I was able to achieve setting $product like this within a block controller on_page_view():

$page = Page::getCurrentPage();
$pageid = $page->getCollectionID();
$db = Loader::db();
Loader::model('product/model', 'core_commerce');
$uh = Loader::helper('urls', 'core_commerce');
$productid = $db->GetOne('select productID from CoreCommerceProducts where cID = ?', array($pageid));
if ($productid > 0) {
$product = CoreCommerceProduct::getByID($productid);

Thank you! This answer helped me get a regular CollectionAttribute value. I didn't know about CollectionAttributeValueObject.
