recursiveTreeNodesAdaptor doesn't go past first level

[stdunbar]

I've seen that some other people have had the same problem I'm having and I wondered if anyone could point me in the right direction.

I'm attempting to use a recursiveTreeNodesAdaptor and, while the root nodes and their children render correctly nothing else does. The environment is RichFaces 3.3.0.GA, Tomcat 6.0.18, Java 1.6.0_10. I've taken out all Hibernate and other variables and have a hard-coded example that still doesn't work. I don't get the second level children nor can I "close" any of the parent nodes. Based on the code below do you have any thoughts? Is there additional debugging I could turn on to see what is happening in the recursiveTreeNodesAdaptor?

Thanks for any help.

<h:form>
 <rich:tree switchType="ajax" stateAdvisor="#{locationStateAdvisor}">
 <rich:recursiveTreeNodesAdaptor roots="#{locationHandler.rootNodes}" var="item" nodes="#{item.children}">
 <rich:treeNode>#{item.locationName}</rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
 </rich:tree>
</h:form>

Code for each node:

import java.util.List;
import java.util.ArrayList;

public class LocationUINode
{
 private String nodeName;
 private ArrayList<LocationUINode> children;

 public LocationUINode( String name )
 {
 nodeName = name;
 children = new ArrayList<LocationUINode>();

 if( nodeName.equals( "Root Node 1" ) )
 {
 children.add( new LocationUINode( "Child 1.1" ) );
 children.add( new LocationUINode( "Child 1.2" ) );
 }
 else if( nodeName.equals( "Root Node 2" ) )
 {
 children.add( new LocationUINode( "Child 2.1" ) );
 children.add( new LocationUINode( "Child 2.2" ) );
 }
 else if( nodeName.equals( "Child 1.1" ) )
 {
 children.add( new LocationUINode( "Child 1.1.1" ) );
 children.add( new LocationUINode( "Child 1.1.2" ) );
 }
 }

 public List<LocationUINode> getChildren()
 {
 // added as the example code does something similar - has no effect
 if( children == null )
 children = new ArrayList<LocationUINode>();

 return children;
 }

 public String getLocationName()
 {
 return nodeName;
 }
}

Code for the managed bean:

import java.util.List;
import java.util.ArrayList;

public class LocationHandler
{
 private ArrayList<LocationUINode> srcRoots = null;

 public List<LocationUINode> getRootNodes()
 {
 if( srcRoots == null )
 {
 srcRoots = new ArrayList<LocationUINode>();
 srcRoots.add( new LocationUINode( "Root Node 1" ) );
 srcRoots.add( new LocationUINode( "Root Node 2" ) );
 }

 return srcRoots;
 }
}

Any pointers or help would be greatly appreciated.

I was able to get the root nodes to open and close by getting rid of the stateAdvisor - the example code must be wrong for that. However, that did not change the lack of recursion.

Hello,

Your code runs ok for me. I can see all levels of nodes and expand/collapse them. Using RF 3.3.0.GA

Thanks for trying it out. But if this is how fragile RichFaces is it isn't for me. Thanks again.
