> #1. Use following page code:
> <a4j:form id="form" eventsQueue="queue">
> 		<rich:tree nodeSelectListener="#{custom.processSelection}"
> 			ajaxSubmitSelection="true" switchType="ajax"
> 			value="#{custom.treeNode}" var="item" ajaxKeys="#{null}"
> 			reRender="theOtherForm,currentNodeText" eventsQueue="queue">
> 		</rich:tree>
> 		<h:outputText escape="false"
> 			value="Selected Node: #{custom.nodeTitle}"
> 			id="currentNodeText" />
> 	</a4j:form>
> 	<a4j:form id="theOtherForm">
> 		<h:inputText id="myInput1"
> 			rendered="#{!custom.secondNodeSelected}"
> 			value="#{custom.nodeTitle}">
> 			<a4j:support event="onchange" reRender="form" eventsQueue="queue" />
> 		</h:inputText>
> 		<h:inputText id="myInput2"
> 			rendered="#{custom.secondNodeSelected}"
> 			value="#{custom.nodeTitle}">
> 			<a4j:support event="onchange" reRender="form" eventsQueue="queue" />
> 		</h:inputText>
> 		<a4j:htmlCommandLink reRender="form" eventsQueue="queue">
> 			<a4j:outputPanel>
> 				<h:outputText value="click me" />
> 			</a4j:outputPanel>
> 		</a4j:htmlCommandLink>
> 	</a4j:form>
> #2. Java bean code:
> import org.richfaces.component.html.HtmlTree;
> import org.richfaces.event.NodeSelectedEvent;
> import org.richfaces.model.TreeNode;
> import org.richfaces.model.TreeNodeImpl;
> public class Custom {
>   private TreeNode currentNode;
>   private TreeNodeImpl firstNode;
>   private String nodeTitle;
>   private TreeNode rootNode;
>   private TreeNodeImpl secondNode;
>   public String getNodeTitle() {
>     if (currentNode != null) {
>       return (String) currentNode.getData();
>     } else {
>       return "unknown";
>     }
>   }
>   public TreeNode getTreeNode() {
>     if (rootNode == null) {
>       createTree();
>     }
>     return rootNode;
>   }
>   public boolean isSecondNodeSelected() {
>     return currentNode == secondNode;
>   }
>   public void processSelection(final NodeSelectedEvent event) {
>     final HtmlTree tree = (HtmlTree) event.getComponent();
>     nodeTitle = (String) tree.getRowData();
>     currentNode = tree.getModelTreeNode(tree.getRowKey());
>   }
>   public void setNodeTitle(final String title) {
>     if (currentNode != null) {
>       currentNode.setData(title);
>     }
>   }
>   private void createTree() {
>     int idx = 0;
>     rootNode = new TreeNodeImpl();
>     firstNode = new TreeNodeImpl();
>     firstNode.setData("Node 1");
>     rootNode.addChild(new Integer(idx++), firstNode);
>     secondNode = new TreeNodeImpl();
>     secondNode.setData("Node 2");
>     rootNode.addChild(new Integer(idx++), secondNode);
>   }
> }
> #3. Navigate to the page.
> #4. Click on the "Node 1" tree node.
> #5. Change input from "Node 1" to "Node 111" and select "Node 2" tree node.
> #6. Verify 1st tree node title.
> Actual behavior:
> It's still "Node 1".
