Here's the action listener for the add child node
command link:
public void createProArgumentationNode(ActionEvent event)
{
ArgumentationNode child = createNode();
ArgumentationNode parent = getCurrentNode();
addEdge(child, parent, true);
/* view updated model data */
focusNode(event, child);
toggleSelectedNode();
}
loadTreeData() gets called twice by the getTreeData()
BEFORE the addition of the new node and once AFTER.
Apparently, the tree model is updated with the previous (old)
data.

Can you post the code for your action listener? I'm curious
to see if loadTreeData() is being called after or before you
updating the tree model.
