<rich:tree> and stateAdvisor problem

[frisch]

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

Hi,

Check that

PostbackPhaseListener.isPostback()

is working right. It should reflect whether current request is postback or not.
