Hi,

We prepared example project to explain issue that we found.

Hi Enova, 
 
When you draw a connector from port to port, the collectionChange event will be triggered. In your sample, you have shown a console for node alone in the collectionChange event.  We have modified it for connectors. Could you please check in the below modified sample? 
 
Code example: 
collectionChange: function(args) { 
                    if(args.state !== 'Changed') return; 
                     
                    var obj = args.element; 
                    if (obj instanceof ej.diagrams.Node) { 
                        var pId = obj.parentId; 
                        console.log('Event: collectionChange', "id: [" + obj.id + "]",  "parentId: [" + pId + "]"); 
                    } 
                    if(obj instanceof ej.diagrams.Connector) { 
                        var pId = obj.parentId; 
                        console.log('Event: collectionChange', "id: [" + obj.id + "]",  "parentId: [" + pId + "]"); 
                    } 
                },
