Problem with dynamic Tree

[ludi]

Hello,

I use the latest version of smartgwt and after updating my code does not work anymore.

I used the example code of the showcase:

 public static final TreeNode employeeRoot = new EmployeeTreeNode("1", "Root",   
            new EmployeeTreeNode("4", "Charles Madigen",   
                    new EmployeeTreeNode("188", "Rogine Leger"),  
                    new EmployeeTreeNode("189", "Gene Porter",   
                            new EmployeeTreeNode("265", "Olivier Doucet"),  
                            new EmployeeTreeNode("264", "Cheryl Pearson")  
                    )  
            )  
    );  
  
    public void onModuleLoad() {  
        Tree employeeTree = new Tree();  
        employeeTree.setModelType(TreeModelType.CHILDREN);  
        employeeTree.setNameProperty("Name");  
        employeeTree.setChildrenProperty("directReports");  
        employeeTree.setRoot(employeeRoot);  
          
        TreeGrid employeeTreeGrid = new TreeGrid();  
        employeeTreeGrid.setWidth(500);  
        employeeTreeGrid.setHeight(400);  
        employeeTreeGrid.setNodeIcon("icons/16/person.png");  
        employeeTreeGrid.setFolderIcon("icons/16/person.png");  
        employeeTreeGrid.setShowOpenIcons(false);  
        employeeTreeGrid.setShowDropIcons(false);  
        employeeTreeGrid.setClosedIconSuffix("");  
        employeeTreeGrid.setFields(new TreeGridField("Name"));  
        employeeTreeGrid.setData(employeeTree);  
          
        employeeTreeGrid.getData().openAll();  
          
        employeeTreeGrid.draw();  
    }  
  
    public static class EmployeeTreeNode extends TreeNode {  
        public EmployeeTreeNode(String employeeId, String name) {  
            this(employeeId, name, new EmployeeTreeNode[] {});  
        }  
  
        public EmployeeTreeNode(String employeeId, String name, EmployeeTreeNode... children) {  
            setAttribute("EmployeeId", employeeId);  
            setAttribute("Name", name);  
            setAttribute("directReports", children);  
        }  
    }

I only changed the employeeRoot to be not static and final to be able to change the attribute. Additionally I added the following method to set new childrends the EmployeeTreeNode:

 public void setNewChildren(EmployeeTreeNode... children) {
	        	setAttribute("childrens", children);  
	        }

First try:
After pressing a button I invoke the method setNewChildren with new children and employeeTree.reloadChildren.
Instead of displaying the new children the Tree is empty.

Second try:
If I create a new root object and add the object as new root node, the tree structure does not work any more. All elements are at the same level (no childs).

TreeNode newEmployeeRoot = new EmployeeTreeNode("1", "Root",   
            new EmployeeTreeNode("4", "Charles Madigen",   
                    new EmployeeTreeNode("188", "Rogine Leger"),  
                    new EmployeeTreeNode("189", "Gene Porter",   
                            new EmployeeTreeNode("265", "Olivier Doucet"),  
                            new EmployeeTreeNode("264", "Cheryl Pearson")  
                    )  
            )  
    );  
 employeeTree.setRoot(newEmployeeRoot);

What is my mistake?
Thanks
