is there a way to disallow disconnected connectors in a diagram? I was looking at the connectionChange event but that does not fire on initial connection of two nodes, only when an existing connector is dragged out / changed.
I need to be able to restrict users from drawing disconnected connectors during runtime. A user adds two nodes on the canvas, then can draw a connector ONLY by hovering over a node and dragging out a connector to target node. Any other drawing of connectors should not be allowed. In other words, a user should be only able to connect nodes, not freely draw any connector anywhere.
Thank you for you help.
