Select and item from PickTreeItem by default

How can I select a tree item by default from a PickTreeItem.

This is a node of the tree:

	public static class DPTN extends TreeNode {
		public DPTN(String id, String name){
			setID(id);
			setName(name);
		}
		
		public DPTN(String id, String name, DPTN... children){
			setID(id);
			setName(name);
			setChildren(children);
		}
	}

setValue(“x”) sets the value of the formitem but does not sets the display value (name property of TreeNode).

I figured out.

IPickTreeItem.setDefault:

public void setDefault(String id){
		TreeNode node = dPTree.find("id", id);
		if(node==null) return;
		String name = node.getName();
		LinkedHashMap<String, String> lhm = new LinkedHashMap<String, String>();
		lhm.put(id, name);
		setValueMap(lhm);
		setValue(id);
	}
