Found a solution for this. Don't know if that is the smoothest way, but if
I call refresh on every ConnectionEditPart the connections get drawn right.
But I have the <...> in the corner. Does someone know what that is
supposed to mean? When I click on it, the connection gets directed there
and I can move it around, but that totally screws up my "Arrange All"
action.
Best regards,
Artur
