Yes, I agree.

Basically, your second question is the answer to the first one. I simply need to know whether this is the first attach or not and also if it is the last detach or not. Depending on this flag (in my interface, the two methods look like this:

  | public void attach(Object inObject, boolean inIsFirst, boolean inIsLocal);
  | public void detach(Object inObject, boolean inIsLast, boolean inIsLocal);
  | 
and are always post), an external processing unit can create related information, delete it, or do nothing. Of course, it would be great if something like this could be included. Unfortunately, I really need it now and my solution seems to work for the moment. It just bothers me that I had to change some of the internals (OTOH, I could also always switch to an entirely external reference counting scheme).

Cheers,
Basil
