Hi, I have an ArrayList which I use to collect data objects from an external source and render them in my Silverstripe template.
But I now find that I need to edit some of the objects in the list, after the list is populated.

If it were an array, I would just do something like

                $key = array_search($id,$my_array);
                if ($key !== false){
                    $my_array[$key]->my_field = $new_value;
                }

...but I can't figure out the syntax to do this in an ArrayList.

Is it possible, or do I need to refactor, to do my edits prior to building the ArrayList?

Cheers!
