Keeping a Map 1-M collection in synch

Question

If you use a HashMap to back a 1-M relationship and the key value changes, the Map is not resynched.
That is, the HashMap still contains the old key and the 1-M relationship is now "corrupt".
What's the best strategy to keep this current?

That sounds like a better approach. Let me see if I understand. Use a method accessor instead of a field accessor in my object where the name changes (getName/setName(String name)).
Doing this will cause this method to be called when other nodes are responding to merge events.
The missing link for me is: what code do I put in this accessor? How do I modify the cache copy holding a reference to this object by name?
I like the idea of using this setter as an "event hook", but I don't know what the hook code should do.
This code would be executing on my working copy. How do I use this to tell the parent object to reindex this object?
