Hierarchy Viewer difference in behaviour between ADF 11.1.1.5 & 11.1.1.6

Question

Hi All,
We are having some problems with the Hierarchy Viewer and we were hoping that someone might be able to shed some light on this issue.
In ADF 11.1.1.5 we have used the attribute displayLevelsChildren which shows how many levels of children would be displayed (if those levels are available of course). We have assigned a value to a select one choice that would set those levels and allow for our user to customise this value and see the levels on right hand side.
You can see the behaviour that I am referring to in the following demo:
http://jdevadf.oracle.com/adf-richclient-demo/faces/feature/hv/hvGroupNode.jspx
I know that this is an 11.1.2, but this has been the same demo for quite a while, when you change the Show Level on the left, the hierarchy viewer gets updated.
I have created a simple app that illustrates the problem, and when I run it under 11.1.1.5 it performs as expected, while when we run it on 11.1.1.6 it doesn't refresh the levels
Versions
Build JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013
Build JDEVADF_11.1.1.6.0_GENERIC_111205.1733.6192.1
The code is below
This is the "dataBean" which is a pageFlowScope.
package au.callista.sms.sr.view;
import java.util.ArrayList;
import java.util.List;
import org.apache.myfaces.trinidad.model.ChildPropertyTreeModel;
import org.apache.myfaces.trinidad.model.TreeModel;
public class DataBean {
     private TreeModel dataModel;
     public DataBean() {
          super();
          DataNode grandfather = new DataNode("Big daddy");
          DataNode father1 = new DataNode("Daddy 1");
          DataNode son1 = new DataNode("Son 1");
          DataNode daughter1 = new DataNode("Daughter 1");
          father1.addChild(son1);
          father1.addChild(daughter1);
          DataNode father2 = new DataNode("Daddy 2");
          DataNode son2 = new DataNode("Son 2");
          DataNode daughter2 = new DataNode("Daughter 2");
          father2.addChild(son2);
          father2.addChild(daughter2);
          DataNode father3 = new DataNode("Daddy 3");
          DataNode son3 = new DataNode("Son 3");
          DataNode daughter3 = new DataNode("Daughter 3");
          father3.addChild(son3);
          father3.addChild(daughter3);
          grandfather.addChild(father1);
          grandfather.addChild(father2);
          grandfather.addChild(father3);
          dataModel = new ChildPropertyTreeModel(grandfather, "children");
     public void setDataModel(TreeModel dataModel) {
          this.dataModel = dataModel;
     public TreeModel getDataModel() {
          return dataModel;
     public class DataNode {
          private String title;
          private List<DataNode> children;
          public DataNode(String title) {
               this.title = title;
               children = new ArrayList<DataNode>();
          public void addChild(DataNode child) {
               this.children.add(child);
          public List<DataNode> getChildren() {
               return children;
          public String toString() {
               return title;

Answer 1

Hi,
the only change is that 11.1.1.6 supports HTML 5 rendering. So you may want to check if the rendering is in Flash or HTML5. If the rendering is in Flash and the mis-behavior shows then the only suggestion I can give is (in case you have a support contract) to file a service request with customer support
