Hi,

is it possible that all opened tree nodes to save, and than if i open this page later the tree openes all opened nodes?
So automatic restore state?

Hello!
This is the way I have done it:
On jsp page:

<r:tree switchType="ajax" binding="#{tree}"
value="#{someBean.data}"
var="item" nodeFace="#{item.type}">

In the upper code "binding="#{tree}"" is important.

And in your bean:

@Name("richTree")
@Scope(ScopeType.CONVERSATION)
public class RichKatalog implements RichKatalogInterface {

 /**
 *
 */
 private static final long serialVersionUID = -259241232787790718L;

 @In(required=false,create=true)
 @Out(required=false)
 private UITree tree;

So you just value binded you tree in the Conversation bean,what means that your tree will save state.
Best regards!

this is also usefull.You can add this methods in your bean too:

 public void expandAll() {
 try {
 tree.queueExpandAll();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }

 public void collapseAll() {
 try {
 tree.queueCollapseAll();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }

Tree is outjected and injected so this will work too.
