Here is the code to edit a copy and then replace it in the collection.
<code>
editContact: aContact
	"overides - comment stating purpose of message"
	
	| copy contacts|
	contacts:= MyContact contacts.
	copy := aContact copy.
	(editor contact: copy) onAnswer: [ :answer |
		"copy has been updated"
		answer ifTrue: [contacts at: (contacts indexOf: aContact) 
put: copy
			] 
 ]
