Hi Joe, If the orderedCollection contains your object DrivingDays then select should give you the object and not a copy.
You don't need to add it back to the collection just update the object. Check your code for anything that might be making a copy.

If I #select the OrderedCollection, I get a copy of the item, not the same one in the OrderedCollection. How do I select an item in the list for update?
