I have a dynamic tree that is retrieving nodetext from database. I also have the implementation for 2 levels of treenode opened when tree is displayed,
What I need now is I want to maintain the state of the tree when I click any leafnode. I tried to follow this link My Link
but, not succesful. I am using attribute componentState from treeComponent, 

<rich:tree switchType="client" stateAdvisor="#{treeStateAdvisor}" componentState="${treeComponentState}">

@Scope(ScopeType.SESSION)
@Name("treeComponentState")
public class TreeComponentState {

     private UITree tree;

     private TreeState treeState;

     public UITree getTree() {
          return tree;
     }

     public void setTree(final UITree tree) {
          this.tree = tree;
     }

     public TreeState getTreeState() {
          return treeState;
     }

     public void setTreeState(final TreeState treeState) {
          this.treeState = treeState;
     }

}

I am not sure if I am using componentState in proper way. How is the tree manipulated to keep the state? Any help is appreciated.
