Adding a node between connections [message #82688]

when i create a connection between two nodes, i want to add another node
automatically, like splitting the new connection.

Is that possible?
Im trying to do this because when i connect two nodes inside different
compartments, the runtime creates two connections.
So its enough for me just to add a node (2px thick) between the other
two, so i get a
CompartmentNode-Connection-Node-Connection-CompartmentNode, bypassing
this problem.

any hints/snippets/magic-commands?
Thanks! ^^

Do u want to avoid creation of two connections, or is it that you
require to create an intermediate node.

In case you want to avoid creation of two connections, then the magic is
as follows:

public class xxxxDiagramCanonicalEditPolicy extends
CanonicalConnectionEditPolicy {
.....

@Override
protected boolean shouldHandleNotificationEvent(Notification event) {
super.shouldHandleNotificationEvent(event);
return false;
}

or else modify the Itemsemanticeditpolicy of the compartment so that
while creation of the connection you can create a node as well!
