What? "uniqueId" is string? It cannot be a string, it has to be an ID,
something gotten with ".object_id", nothing else will do. And two strings
with the same content do not necessarily have the same ID.

In your method "uniqueId", you should be returning "self.object_id".

In your code, I do not see where you acquire the ".object_id" of any object.

Very basically, in order to solve a problem like this, you simply must post
a short, terse, concise bit of code, that (1) can be run by a newsgroup
reader, and (2) shows the problem.

Posting bits and pieces of code, but never a short working example, is a
sure way to assure that this thread will go on forever.
