	Hi, I have a decision node with anchor pattern apat1 = new AnchorPattern([ new AnchorPoint(50, 0, true, false), new AnchorPoint(100, 50, true, true), new AnchorPoint(0, 50, true, true)]); created link using var dlink = diagram.getFactory().createDiagramLink( originnode,targetnode]); then created connection points for decision node using origin.createConnectionPoint(dlink, apat1.points[0],true); origin.createConnectionPoint(dlink, apat1.points[1], false); origin.createConnectionPoint(dlink, apat1.points[2], false); created treelayout var treeLayout = new TreeLayout(); treeLayout.linkType = TreeLayoutLinkType.Cascading; treeLayout.anchoring = Anchoring.Reassign; diagram.arrange(treeLayout); The issue i am facing is the out going links from the decision node is always originating from the (100,50) anchor point. I need the out going links from (0,50) and (100,50) points. I am using the JS 1.3 beta version. Please guide me on how to fix this. Thanks

	I have two decision nodes and i want to create link from (0,50) anchor point from the origin node to (50,0) point of the destination node. Below is my code apat1 = new AnchorPattern([new AnchorPoint(50, 0, true, false),new AnchorPoint(100, 50, false, true),new AnchorPoint(0, 50, false, true)]); var diagramNode1 = diagram.getFactor().createShapeNode(bounds); diagramNode1.setShape("Decision"); diagramNode1.setText("Decision1"); diagramNode1.setAnchorPattern(apat1); var diagramNode2 = diagram.getFactory().createShapeNode(bounds); diagramNode2.setShape("Decision"); diagramNode2.setText("Decision2"); diagramNode2.setAnchorPattern(apat1); var dlink = diagram.getFactory().createDiagramLink( diagramNode1,diagramNode2); diagramNode1.createConnectionPoint(dlink, new point(0, 50), false); diagramNode2.createConnectionPoint(dlink, new point(50, 0), true); dlink.route(); var treeLayout = new TreeLayout(); treeLayout.linkType = TreeLayoutLinkType.Cascading; treeLayout.anchoring = Anchoring.Reassign; diagram.arrange(treeLayout); But the link is always drawn from the (100,50) anchor point. what could be the wrong here?Thanks in advance.

	It seems TreeLayout selects the AnchorPoint that is at minimal distance from the origin node's center-bottom point, instead of checking the destination node postions. You could call this after applying TreeLayout as a work-around: Code Array.forEach(diagram.links, function (link) { var connection = link.originConnection; connection.chooseBestAnchorPoint(link.getEndPoint()); link.points[0] = connection.anchorPointDetails.point; link.route(); }); I hope that helps, Stoyan

	Call the link's setOriginAnchor and setDestinationAnchor methods. I hope that helps, Stoyan
