Hi Terry,
What I was looking for originally was a way to artificially create a
complete change list from an existing model. I would think that would
be a simpler way to reestablish a broken connection because you
wouldn't have to keep a record of all changes since the start of the
client. Has this method been considered?
Yes I actually wanted the same but that's not so easy to implement so I
hacked this workaround.

Again, I'm probably not seeing the real problem, but what makes this
difficult? From what I gather from the OpenSG docs, a ChangeList can
contain items for create, destroy, change, addref, and subref.
Couldn't we just traverse a graph and compile a ChangeList full of
create and addref items? I haven't written much traversal code, but I
don't remember it being so bad. I'd be willing to try writing this,
unless there's some big obstacle I haven't thought of.

Not everything is referenced in the scenegraph (Window, Viewport,
Camera, ...) so this doesn't work. You could iterate over the
FieldContainer list.
const vector<FieldContainerPtr> &fcs =
*FieldContainerFactory::the()->getFieldContainerStore();
for(int i=0;i<fcs.size();++i)
{
FieldContainerPtr fc = fcs[i];
if(fc != NullFC)
{
// create a changelist.
}
}
I tried it once and it didn't work I think it was a problem with
prototypes or reference counts. If you like you can try to code it. I
think this approach is much nicer than my hack.
