Richfaces demo site source is included in sources.zip file. You can find it on download page.

But I want to have many nodes, and each one of different them with icon!
In the example of this site they are not worried very about this !

I do not know as to decide this!
not meeting in place some the solution..

[maksimkaszynski]

Both tree and treeNode component have following attributes iconCollapsed, iconExpanded, iconLeaf, icon.
You can set values for them using EL.
For example,

<rich:tree value="#{bean.data}" var="data" icon="#{data.icon}">

All you need then is to add icon property to your data type.

I am trying to add the icon to my data, as suggested above but I must be missing something because I keep getting:

Error getting property 'icon' from bean of type java.lang.String

Here's my code:

import org.richfaces.model.TreeNodeImpl;

public class TreeIconNodeImpl extends TreeNodeImpl {


 private static final long serialVersionUID = 1L;
 private String type;
 private String icon;


 public TreeIconNodeImpl(String type, String icon){
 super();
 this.type = type;
 this.icon = icon;
 }

 public String getType() {
 return type;
 }

 public void setType(String type) {
 this.type = type;
 }

 public String getIcon() {
 return icon;
 }

 public void setIcon(String icon) {
 this.icon = icon;
 }

}

 public TreeNode getTreeNode() {
 if (rootNode == null) {
 loadTree();
 }
 return rootNode;
 }

private void loadTree(){

 rootNode = new TreeNodeImpl();

 // Add the gateway to the root
 TreeIconNodeImpl gwNode = null;
 gwNode = new TreeIconNodeImpl("gateway", "/img/net_wired.gif");
 gwNode.setData("Gateway");
 rootNode.addChild(1, gwNode);

 int gwCount = 1;

 TreeIconNodeImpl optNode = null;
 optNode = new TreeIconNodeImpl("option", "/img/app_winamp_small.gif");
 optNode.setData("Network Settings");
 gwNode.addChild(gwCount++, optNode);

 optNode = new TreeIconNodeImpl("option", "/img/app_winamp_small.gif");
 optNode.setData("Wireless Settings");
 gwNode.addChild(gwCount++, optNode);
}

 <rich:tree style="width:300px" nodeSelectListener="#{gwTreeBean.processSelection}"
 reRender="selectedNode" ajaxSubmitSelection="true" switchType="client"
 value="#{gwTreeBean.treeNode}" var="item" icon="#{item.icon}">

 </rich:tree>
