I don't know why this:
$attributeCollection = Mage::getResourceModel('myext/attributelist_collection') //$attributeCollection = Mage::getModel('myext/attributelist')->getCollection() ->addFieldToFilter('to_export', array('eq' => 1)) ->getSelect()->order('order DESC');
Isn't working, when the query I get with
__getSelect() is correct and works when I execute it directly in the console.
The line commented is another try that doesn't work.
