Adding new NodeSet

[viihallja]

Hello,

I am trying to add new NodeSet to topology using the addNodeSet method. However I get "Cannot read property 'parentVertexSetID' of undefined" error. See this fiddle: NeXt nodeset - JSFiddle

What am I missing?

addNodeSet is a low level API, you missed second parameter as config, it should look like this:

topo.addNodeSet(topologyData.nodeSet[0],{})

I will update NeXt make the second parameter as optional.

Thanks, I was able to figure it out by looking at the code.

I have a couple of questions. Is there a method for removing NodeSet from topology? I tried the removeNode method but couldn't make it work. What about adding node to existing NodeSet?

I made a demo, you can refer it. Add node to nodeSet could be a little bit tricky. We don't have that feature before.

Thanks Abu. Any change of implementing the add node to nodeSet method? I would like to be able to add new node to nodeSet without reloading the dataset.

In this demo(removeNode&insertNodetoNodeSet - JSFiddle) I implement a function called 'addNodeToNodeSet', you can use this function. I am not add that to framework yet.

function addNodeToNodeSet(topo, pid, nodeData) {
  if (!topo || !pid || !nodeData) {
    return;
  }
  var graph = topo.graph();
  var nodeSet = topo.getNode(pid);
  if (nodeSet) {
    var vertexSet = nodeSet.model();
    var vertex = graph._addVertex(nodeData);
    vertexSet.addVertex(vertex);
    graph.updateVertexSet(vertex);
    if (!nodeSet.collapsed()) {
      var animation = nodeSet.animation();
      nodeSet.animation(false);
      nodeSet.collapsed(true);
      nodeSet.collapsed(false);
      nodeSet.animation(animation);
    }
  }
}

Thanks Abu, I got it working.
