    copied!<p>I'm running Primefaces 3.2 and JSF 2.0 on Glassfish 3.</p> <p>I've tried a lot, to programatically set the selected node from a managed bean. That includes setting the selected node like this:</p> <pre><code>public void setSelectedTreeNode(String name) { TreeNode root = treeBean.getRoot(); List&lt;TreeNode&gt; tree = root.getChildren(); for(TreeNode node:tree) { if(node.getData().toString().contains(name)) { System.out.println("found the node to select"); treeBean.setSelectedNode(node); break; } } RequestContext context = RequestContext.getCurrentInstance(); context.update(":navForm:treeSingle"); } </code></pre> <p>The "found the node to select" gets printed in the terminal, but the node is not selected in the Tree in the web page..</p> <p>The tree is like this:</p> <pre><code>&lt;h:form id="navForm"&gt; &lt;p:tree id="treeSingle" value="#{treeBean.root}" var="node" selectionMode="single" styleClass="treeStyle" selection="#{treeBean.selectedNode}" cache="false" &gt; &lt;p:ajax event="select" listener="#{treeBean.onNodeSelect}" update=":mainForm" /&gt; &lt;p:treeNode&gt; &lt;h:outputText value="#{node}" escape="false" /&gt; &lt;/p:treeNode&gt; </code></pre> <p> </p> <p>Edit: TreeBean is built like this:</p> <pre><code>@ManagedBean @SessionScoped public class TreeBean implements Serializable { private TreeNode root; private TreeNode selectedNode; public TreeBean() { root = new DefaultTreeNode("Root", null); TreeNode node0 = new DefaultTreeNode("Node 0", root); TreeNode node1 = new DefaultTreeNode("Node 1", root); TreeNode node2 = new DefaultTreeNode("Node 2", root); TreeNode node00 = new DefaultTreeNode("Node 0.0", node0); TreeNode node01 = new DefaultTreeNode("Node 0.1", node0); TreeNode node10 = new DefaultTreeNode("Node 1.0", node1); TreeNode node11 = new DefaultTreeNode("Node 1.1", node1); TreeNode node000 = new DefaultTreeNode("Node 0.0.0", node00); TreeNode node001 = new DefaultTreeNode("Node 0.0.1", node00); TreeNode node010 = new DefaultTreeNode("Node 0.1.0", node01); TreeNode node100 = new DefaultTreeNode("Node 1.0.0", node10); } public TreeNode getRoot() { return root; } public TreeNode getSelectedNode() { return selectedNode; } public void setSelectedNode(TreeNode selectedNode) { this.selectedNode = selectedNode; } } </code></pre> <p>Does anyone have any idea on how to do this?</p>
