ADF tree doesnot remain expanded when sublinks are clicked

Question

i have a left vertical navigation menu implemented in af:tree.
i used the code below :
*<af:tree var="node"*
*value="#{navigationContext.currentNavigationModel.treeModel['startNode=/,*
includeStartNode=true,
depth=1']}"
id="t1">
*<f:facet name="nodeStamp">*
*<af:outputText value="#{node.title}" id="ot1"/>*
*</f:facet>*
*</af:tree>*
available in the the oracle documentation : http://docs.oracle.com/cd/E17904_01/webcenter.1111/e10148/jpsdg_view_comps.htm
The problem is, when the link is clicked, i get redirected to the correct page, but the tree is collapsed again. I want to disclose the nodes of the current page path.
i focused on the af:tree documentation and tried to build a set of rowKey in a managed bean in order to affect it to the disclosedRowKeys attribute... but i was completly lost !!
Thanks for help.

I am also facing this issue. Is there any solution to this.
I tried to do it programatically but problem is ADF code that expands all nodes of tree works with tree having JUCtrlHierNodeBinding. But in case of Navigation model we don't get JUCtrlHierNodeBinding
private void expandAllNodes(JUCtrlHierNodeBinding nodeBinding,
RowKeySetImpl disclosedKeys,
int currentExpandLevel, int maxExpandLevel) {
String methodName = Thread.currentThread().getStackTrace()[1].getMethodName();
if (_logger.isLoggable(Level.INFO)) {
_logger.info("Class: [" + this.getClass().getName() + "] [" + methodName + "]" + "Start" );
if (currentExpandLevel <= maxExpandLevel) {
List<JUCtrlHierNodeBinding> childNodes =
nodeBinding.getChildren();
ArrayList<Object> newKeys = new ArrayList<Object>();
if (childNodes != null) {
for (JUCtrlHierNodeBinding _node : childNodes) {
newKeys.add(_node.getKeyPath());
expandAllNodes(_node, disclosedKeys,
currentExpandLevel + 1, maxExpandLevel);
disclosedKeys.addAll(newKeys);
if (_logger.isLoggable(Level.INFO)) {
_logger.info("Class: [" + this.getClass().getName() + "] [" + methodName + "]" + "End" );
Is there anything I can try?
Thanks
