<rich:tree> Example reRender not working Richfaces 3.3.4 final
Hey Community,
i'm using Richfaces 3.3.4 final with JSF 1.2 on a SAP NetWeaver AS 7.31.
Now im facing some Issues with dynamically showing selected Nodes from a rich:tree in a h:outputText. The selectedNodeListener is invoked correctly and the Name of the Node is saved in a String, but my h:outputText only refreshes on Page Refresh and not on Selection like in the Example from the Showcases(http://showcase-rf3.richfaces.org/richfaces/tree.jsf?tab=model&cid=26981).
Does anyone know if this is a common Issue with the above Setup or am I just missing something? As far as I know SAP NetWeaver isnt in the List of supported Servers but its JEE5 compliant. Could this be the Reason?
I simplified the the Example from the Richfaces Showcases to reproduce the Problem in a small Environment. Here is some Code:
SimpleTreeBean.java
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.richfaces.component.html.HtmlTree;
import org.richfaces.event.NodeSelectedEvent;
import org.richfaces.model.TreeNode;
import org.richfaces.model.TreeNodeImpl;
public class SimpleTreeBean {
private TreeNode rootNode = null;
private List<String> selectedNodeChildren = new ArrayList<String>();
private String nodeTitle;
private void loadTree() {
rootNode = new TreeNodeImpl();
TreeNodeImpl rt = new TreeNodeImpl();
rt.setData("Root");
rootNode.addChild(1, rt);
for(int i = 1; i <= 5; i++){
TreeNodeImpl child = new TreeNodeImpl();
child.setData("Child "+i);
rt.addChild(i, child);
}
}
public void processSelection(NodeSelectedEvent event) {
HtmlTree tree = (HtmlTree) event.getComponent();
nodeTitle = (String) tree.getRowData();
selectedNodeChildren.clear();
TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());
if (currentNode.isLeaf()) {
selectedNodeChildren.add((String) currentNode.getData());
} else {
Iterator<Map.Entry<Object, TreeNode>> it = currentNode
.getChildren();
while (it != null && it.hasNext()) {
Map.Entry<Object, TreeNode> entry = it.next();
selectedNodeChildren.add(entry.getValue().getData().toString());
}
}
}
public TreeNode getTreeNode() {
if (rootNode == null) {
loadTree();
}
return rootNode;
}
public String getNodeTitle() {
return nodeTitle;
}
public void setNodeTitle(String nodeTitle) {
this.nodeTitle = nodeTitle;
}
}

Important Part of faces-config.xml:
<?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd" version="1.2"> <managed-bean> <managed-bean-name>simpleTreeBean</managed-bean-name> <managed-bean-class> com.realcore.web.beans.SimpleTreeBean </managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> </faces-config> <</faces-config>/faces-config>
Additionally there are some Validators and Converters in my faces-config too. But I think this isnt important for this Problem.
And here is the web.xml:

This simple Example isnt working too.
I don't know how to fix or workaround this Issue. Any help is greatly appreciated.
