Lead Selection in tree by nesting table column compatibility nw04plus

Hello guys,

Please let me know a solution for the following issue.

I have a tree by nesting table column in a similar fashion.

==RootElement1

-

---

.childElement1

-

---

.childElement2

-

---

.childElement3

==RootElement2

-

---

.childElement1

-

---

.childElement2

-

---

.childElement3

The table column has a check box as the table cell editor. In this case, when i check the root element, all the child elements pertaining to the selected rootelement will be selected and vice versa. now when i uncheck the child element, the root element will also get unchecked. I am using the code as below to do the same.

<DO modify view>

if(firstTime)
    {
    	IWDTreeByNestingTableColumn tableColumn = (IWDTreeByNestingTableColumn)view.getElement("MasterColumn");
    	tableColumn.mappingOfOnLoadChildren().addSourceMapping("path","element");
    	
    	IWDCheckBox checkBox = (IWDCheckBox)view.getElement("CheckBox");
    	checkBox.mappingOfOnToggle().addSourceMapping("nodeElement","nodeElement");
    	
    }

<Action ontoggle of the checkbox>
 public void onActionToggleBox(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.arteriatech.demo.wdp.IPrivateDemoCompView.IVnTreeNodeElement nodeElement )
  {
    //@@begin onActionToggleBox(ServerEvent)
    
    if(nodeElement.getVaCheck() && !nodeElement.getVaIsLeaf())
    {
    	for(int i=0;i<nodeElement.nodeRecTree().size();i++)
    	{
    		nodeElement.getRecTreeElementAt(i).setVaCheck(true);
    	}
    }
    else if(!nodeElement.getVaCheck()) 
    {
		if(!nodeElement.getVaIsLeaf())
		{
			for(int i=0;i<nodeElement.nodeRecTree().size();i++)
			{
				nodeElement.getRecTreeElementAt(i).setVaCheck(false);
			}
						
		}
		else
		{
			int curr_sel = nodeElement.node().getParentElement().node().getLeadSelection();
			wdComponentAPI.getMessageManager().reportSuccess("1-->"+nodeElement.node().getLeadSelection());
			wdComponentAPI.getMessageManager().reportSuccess("2-->"+curr_sel);
			wdContext.nodeVnTreeNode().getVnTreeNodeElementAt(curr_sel).setVaCheck(false);

		}
		
    }

Please note,

This scenario works fine when i have the table property selection mode = none, compatibility mode = auto. But when i change the compatibility mode to nw04plus, the first root element gets unchecked when i uncheck the child element belonging to other root elements i.e., the lead selection of the root element always remains 0.

Hence let me know a solution for the same.
