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.
All the best,

I have a OrderedCollection of DrivingDays.
an OrderedCollection(2016-01-02| quigley s| nil|18§
2016-01-03| marianos fresh| nil|5§
2016-01-04| fresh thyme| nil|5§
2016-01-05| panda express| nil|3§
2016-01-06| peets| nil|7§
2016-01-07| starbucks| nil|3§)
I want to select aDrivingDay object from the list by date, update it by adding mileage and places visited and put it back into the list.
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?
