I want know how can I implement tree view with Struts2 jquery tree plugin 4.0.3, seems there are major changes in the newer version compared to older one.

this is the existing block of code before updating Struts2 jquery tree plugin version

nodeOrder.setTitle(order.getNumber()+" / "+sdf.format(order.getCreateDate()));
nodeOrder.setState(TreeNode.NODE_STATE_LEAF);

if(item.getProduct()!=null && item.getProduct().getName()!=null && !"".equals(item.getProduct().getName()) && item.getProduct().getName().equals(searchFilterDTO.getProductName())){
nodeOrder.setState(TreeNode.NODE_STATE_OPEN);
                                      nodeItem.setState(TreeNode.NODE_STATE_OPEN);
}

if(!TreeNode.NODE_STATE_OPEN.equals(nodeOrder.getState())){                   nodeOrder.setState(TreeNode.NODE_STATE_CLOSED);
}

In the newer version 4.0.3 the setTitle method and TreeNode.NODE_STATE_CLOSED Enums are not present, as a result I have modified above code block to

nodeOrder.setText(order.getNumber()+" / "+sdf.format(order.getCreateDate()));
nodeOrder.setHasChildren(false);

if(item.getProduct()!=null && item.getProduct().getName()!=null && !"".equals(item.getProduct().getName()) && item.getProduct().getName().equals(searchFilterDTO.getProductName()))
{
                  nodeOrder.getState().setOpened(true);
                   nodeItem.getState().setOpened(true);
}

if(!nodeEnt.getState().isOpened()){
  nodeEnt.getState().setOpened(false);
}

even though the tree view is not proper.

result from updating struts2-jquery-tree-plugin to 4.03
This is what I am expeting
