Hi again,
Thanks first of all for the quick and helpful response to my last
question.
At the moment I am trying to create an actor that will store and be
able to show relations and links without having a graphical link
displayed (in Vergil). For my purposes there are too many connections
needed that using a regular click-and-drag relation will result in too
much clutter on the graph editor so I would like to add the relations
and links manually. In this regard (and looking at the very simple
model (code below):
1. How do I name ports that they will be recognised as the same as the
ones shown in the model (some sort of global name??). If I create
all the actors and their ports from my own Java program this is not an
issue but if Vergil creates them how does it name, how can I refer to
objects it has created?
2. A submodel is a TypedCompositeActor object as I understand it?
Regarding setting a Director at the top level (above all submodels)
what do I use to add it to? Does the empty graph editor have a type?
CompositeEntity/CompositeActor? (only CompositeActor has a
setDirector() method) And if so, does this have a name?
Thanks again for any help you can give me,

submodel)
