Hello!
The following code doesn't work:

<rich:tree value="#{testTreeBean.data}" treeNodeVar="item">
 <rich:treeNode
 iconLeaf="images/tree/leaf.gif"
 icon="/images/tree/folder.gif"
 rendered="#{!item.error}">
 <h:outputText value="#{item.data}" />
 </rich:treeNode>

 <rich:treeNode
 iconLeaf="images/tree/leaf_e.gif"
 icon="/images/tree/folder_e.gif"
 rendered="#{item.error}">
 <h:outputText value="#{item.data}" />
 </rich:treeNode>
</rich:tree>

TestTreeBean.java:

 public CustomTreeNode getData() {
 CustomTreeNode root = new CustomTreeNode();
 root.setData("Root");

 CustomTreeNode folder1 = new CustomTreeNode();
 folder1.setData("folder1");
 CustomTreeNode folder2 = new CustomTreeNode();
 folder2.setData("folder2");

 root.addChild(1, folder1);
 root.addChild(1, folder2);

 return root;
 }

CustomTreeNode.java:

public class CustomTreeNode extends TreeNodeImpl<String> {

 private boolean isError;

 public boolean isError() {
 return isError;
 }

 public void setError(boolean isError) {
 this.isError = isError;
 }

}

After expanding some node the following error is risen:
javax.servlet.ServletException: javax.el.PropertyNotFoundException: /h1.xhtml @30,30 rendered="#{!item.error}": Property 'error' not found on type org.richfaces.model.TreeNodeImpl

I.e. during ApplyRequestValuesPhase tree contains TreeNodeImpl nodes, not nodes from value property: CustomTreeNode.

Why treeNodeVar variable refers to these strange nodes?

Thank you,
Alexey
