hi everybody,

I have the following code

<rich:tree value="#{treeElem.trees}" var="item" stateAdvisor="#{treeDemoStateAdvisor}" switchType="ajax" >
 <rich:treeNode changeExpandListener="#{handler.processExpansion}">
 <h:outputText value="#{item.id} #{item.name}" />
 </rich:treeNode>
</rich:tree>

The problem is that when I use the stateAdvisor my tree nodes are expanded but they cannot be collapsed again. It works only when I switch to client but I cannot use the changeExpandListener in that state.

Here is my TreeDemoStateAdvisor

@Name("treeDemoStateAdvisor")
public class TreeDemoStateAdvisor implements TreeStateAdvisor {

 public Boolean adviseNodeOpened(UITree tree) {

 if (!PostbackPhaseListener.isPostback()) {
 Object key = tree.getRowKey();
 TreeRowKey treeRowKey = (TreeRowKey) key;
 if (treeRowKey == null || treeRowKey.depth() <= 20) {
 return Boolean.TRUE;
 }
 }

 return null;
 }

 public Boolean adviseNodeSelected(UITree tree) {
 return null;
 }

}

does anybody have any ideas about this?

I'm currently working with the 3.3.2.SR1 version from richfaces

thanks
