Creating EPS tree using Primavera API

Hi Guys,

I am trying to create the EPS tree using Primavera API for my program using below code.

What I did I connect to database then I read all the EPS and project object ID, Name, parent object ID, and Parent Name is the ArrayList.

When I am creating the tree using Only object ID the tree is displaying fine but when I am trying to do the same with name I am getting an error stack overflow.

Did any body done that before?

Below is my code.

public class TestingBOHierarchyMap {

 

static List<Node> nodeList = new ArrayList<Node>();;
