How can I get this to sort by "Food Name"?
$obj = new SiteConfig_DataObjectManager(
$this->owner,
'Food',
'Food',
array('Plant'=>'Plant','FoodName'=>'Food Name'),
'getCMSFields_forPopup'
);
$obj->setSourceID($this->owner->ID);
$obj->setAddTitle("Food Pages");
$fields->addFieldToTab("Root.Content.Custom", $obj);
