[gme-users] addon creation

[Matthew J. Emerson]

I'm really just trying to populate an attribute of a reference with the
name of its referent, and keep those two things consistent in all
circumstances.

I'm running into some problems:
*	It is not possible to initialize the attribute to the correct
value when the reference is created directly from the referent (using
ctrl+shift or paste-as-reference). This is because the object creation
event is produced before the reference is directed to point to the
referent.
*	Similarly, the 'REFERENCED' event is not produced for the
referent when a new reference is created using ctrl+shift or
paste-as-reference.
*	None of the events seem to be keyed to the action of changing
which object a reference points to.

Matt,

I am pretty sure that your addon will get called again. But if you 
remember the aatr value the code set and compare it to the value you get

and then do nothing if they agree, you break free from the recursion...

Or am I missing something?
