nodePosition(Graph, String) returns (0,0,0)

[Zacharie ALES <zacharie.ales AT gmail.com>]

Hello,

I recently switched to the nightly build version. Everything works fine except the nodePosition function that I am using to center the view on one specific node. 

An exemple : 

    public void centerView(String id)
    double[] d = org.graphstream.ui.graphicGraph.GraphPosLengthUtils.nodePosition(myGraph,id);
    System.out.println(d[0] + ", " + d[1] + ", " + d[2]);  // Display "position : 0.0, 0.0, 0.0"
    }

I checked the id and it is correct (myGraph.getNode(id) == null returns false). Is it a bug or do I miss something ?

Thanks in advance for your help.
