Personalization on a nodeDefintion in a hgrid

Question

PageLayout => abCO.java
-DefaultSingleColumn:
--TableLayout:(leBsvAssignTableLayout)
---RowLayout:(leBsvRowLayout)
----CellFormat:(bsvAssignTableCell)
-----HGrid:(hgrid)
------Tree:(treeId)
-------Members
--------Node Def:(objectName)
---------Child Node:(bsvAssignments)
----------Members
-----------Node Def:(bsvAssigned)
There is a controller abCO.java for the PageLayout Region
My requirement is to attach a link to the leafnode(bsvAssigned). I tried extending the CO and code is like this
public class myExtCO extends abCO{
processRequest(pageContext,webBean){
super.processRequest(pageContext, webBean);
OATreeDefinitionBean bsvValNode = (OATreeDefinitionBean)webBean.findChildRecursive("bsvAssigned");
String url = "OA.jsp?page=/oracle/...";
if(bsvValNode!=null){
bsvValNode.setDestination(url);
else{
throw new OAException("node not found.");
The bsvValNode is not found. Can u help me in debugging this?

processRequest(pageContext,webBean){
..OAHGridBean.hgrid.=.null;
..OATreeBean..tree..=.null;
..OATreeDefinitionBean.node.=.null;
..String.url.=."/oracle/apps/cle/webui/somePage";
....hgrid=.(OAHGridBean)webBean.findIndexedChildRecursive("hgridId");
....if(hgrid!=null){.
......tree.=.(OATreeBean)hgrid.findIndexedChildRecursive("treeId");.
......if(tree!=null){
........node.=.(OATreeDefinitionBean)tree.findIndexedChildRecursive("bsvAssigned");.
........if(node!=null){
..........node.setDestination(url);
........else{
..........throw.new.OAException("node.not.found");
......else{
........throw.new.OAException("tree.not.found");
....else{
......throw.new.OAException("hgrid.not.found");
Output: "tree.not.found"
