Hi everyone
I have tried using rich-faces tree, but quite frankly
am not able to display a tree.
Note that other rich-faces components are being displayed correctly.
I followed this
http://www.jboss.com/index.html?op=loginscreen&module=user
and this http://www.jboss.com/index.html?op=loginscreen&module=user
but still got no-where!
Is there anyone using rich-faces tree?I will greatly appreciate any help.
Environment:
seam 1.2.1 GA
jboss-4.0.5 GA
richfaces-3.0.1-SNAPSHOT.jar
Here is the Node :
| package com.triad.treeNodes;
|
| import java.util.Iterator;
| import java.util.LinkedHashMap;
| import java.util.Map;
|
| import org.jboss.seam.ScopeType;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Scope;
| import org.richfaces.component.TreeNode;
|
| @Name("tree")
| @Scope(ScopeType.PAGE)
| public class RichTreeNode implements TreeNode {
|
| /**
| *
| */
| private static final long serialVersionUID = 1L;
|
| // private TreeNode treeNode;
| private String name;
|
| private String type;
|
| private Map<Object, TreeNode> childrenMap = new LinkedHashMap<Object,
TreeNode>();
|
| public Object getData() {
| // return treeNode;
| return this;
| }
|
| public void setData(Object arg0) {
|
| }
|
| public boolean isLeaf() {
| return childrenMap.size() == 0;
| }
|
| public Iterator getChildren() {
| return childrenMap.entrySet().iterator();
| }
|
| public TreeNode getChild(Object identifier) {
| return childrenMap.get(identifier);
| }
|
| public void addChild(Object identifier, TreeNode treeNode) {
| childrenMap.put(identifier, treeNode);
|
| }
|
| public void removeChild(Object arg0) {
| // TODO Auto-generated method stub
|
| }
|
| public TreeNode getParent() {
|
| return null;
|
| }
|
| public RichTreeNode() {
|
| this.name = "parent-node";
| this.type = "root";
|
| }
|
| public void setParent(TreeNode arg0) {
| // TODO Auto-generated method stub
|
|
| }
|
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
|
| public String getType() {
| return type;
| }
|
| public void setType(String type) {
| this.type = type;
| }
|
| }

| RichTreeNode node1=new RichTreeNode();

| node1.setType("leaf");
|
| richTree.addChild("node1",node1);
| log.info("the tree with children *********");
| Iterator it=richTree.getChildren();
| while(it.hasNext()){

| }
| }
|
| public RichTreeNode getRichTree() {
|

|
