Hey,
My problem is as follows. I have 2 types of object a Box and a Container.
A Box can be connected to another Box.
A Container contains zero to many Boxes.
When a Box is in a Container it appears smaller as the zoom on the Container
is set to 50%, this is so I can fit more in there.
A Box maintains its connections even when moved into a Container (or back
out again)
When I double-click a Container I open a new editor which shows just the
contents of the Container.
If two Boxes in a Container are connected then these connections are shown
fine in the new Container editor.
However the problem occurs if I have a Box inside the Container connected to
a Box outside the Container.
In this case when I open the Container editor the connection had no endpoint
as the Box that it was connected to is not shown.
So I need to find a way around this problem.
I was thinking that if I had a connection that had no Box on the end in the
Container editor then I could create some kind of temporary or marker figure
just to signify the fact that there is a connection to something outside the
current Container/Editor.
Anybody had any experience with anything like this or got any ideas on how
this could be achieved ?
Regards,
Alan.

You have an edit part factory used by your comtainer editor return a
special 'connection' edit part. That 'connection' edit part should know
if its connected to a box which is not within the editor, and draw
itself accordingly, or not at all.
