I have the situation, that when I create a Node, I automatically want to
create a second one which is connected to the first one. This is allready
working, I just overwrote the xxxCreateElementCommand where I create the new
Model and add it to it's container. So both models were created and
correctly added ans setup. So this is fine.
But the 'missing' piece is the connection between this two nodes, it is not
visible/created. Some times ago I used GEF, back then I had to create the
connetion manually in the Command. Do I need to do this here too? And if so
how?
Actuall I personally guess this is just a refresh problem, beause when I
save the diagram and reopen it the connection is drawn.

I'm pretty sure you're right. The Problem is, how to tell the notation model
that it should now 'resync' oder whatever is needed to display the
Connection.
