Hi there,
I'm using version 10.1.0.44.

My need is to check when a connection between two nodes is newly created or is modified dragging head or tail of a just dragged connector.

When a connection is created the event AfterConnecionCreate never fires. So I had to use TailNodeChanged and HeadNodeChanged in combination to understand when a new connection is valid.

But such events do not fire when the user changes head or tail of a connector dragging with mouse pointer, It's strange as head or tail change in that case.

So I tried to use the event ConnectorDragEnd, ok it is fired but twice! it's not a good behaviour if you want to run code to understand if a connector is loosing head or tail attachment.

I attach a simple solution on which you can very such cases.
Best regards
Domenico Mozzone
