We have a bit of code that looks like this:
$products = Mage::getModel('catalog/product')->getCollection(); $products->addAttributeToSelect('name'); $products->addAttributeToSelect('sellbydate'); $products->addAttributeToSort('sellbydate','ASC');
This has been working fine, but after enabling flat product data the items are no longer sorted. I have reindexed but there is no change.
Should I be using a different function?
