	Hi, I want to know whether the following things are possible to implement. 1. to set a node not deletable but it allows outgoing links. 2. to limit a node to certain outgoing links , like node should permit only one outgoing link.

	Hi, You can do both by handling some validation events, e.g. nodeDeleting, linkCreating, linkModifying. I hope that helps, Stoyan

	hi, For outgoing links it can be done by deleting link which is exceeding limit on linkcreate event. But how to set node not deletable?

	Hi, Handle DiagramListener.nodeDeleting() and call e.setCancel(true). I hope that helps, Stoyan

	hi, I am doing it as following but it shows e.setCancel(Boolean) method is undefined for NodeEvent diag.addDiagramListener(new DiagramAdapter() { public void nodeDeleting(NodeEvent e) { DiagramNode deletedNode = e.getNode(); if(deletedNode.getTag().toString().equals("1")) { e.setCancel(true); } }

	The method signature should be void nodeDeleting(NodeValidationEvent e); I hope that helps, Stoyan
