Hallo everybody.
Before I posted this topic, I tried to find possibly related sollutions on this forum and internet with no success.

I use richfaces in portlet environment, JBoss Portal 2.7.1 RichFaces 3.3.0GA and JSF 1.2 Facelets 1.1.1.4 and Spring 2.5 and have succesfully rendered default tree.

I wanted to customize my nodes with custom icons,so I looked for example http://livedemo.exadel.com/richfaces-demo/richfaces/tree.jsf?tab=usage&cid=2364871

If I hard code my nodeFace in the tree, I have no problem.

I thought I add my nodeFace dinamically so I extended the TreeNodeImp and added new property type with it's Getter and Setter methods.

public class CustomNodeType extends TreeNodeImpl{

 private String type;

 public CustomNodeType (){
 super();
 }

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

 public String getType() {
 return type;
 }

}

During the loading of the tree, I set the type of each node, dependent of my Data Object type I have to load on in the tree.


In the xhtml I have the tree something like this:

<rich:tree nodeSelectListener="#{treeProvider.selectNode}" reRender="selectedNode" ajaxSubmitSelection="true"
switchType="ajax" treeNodeVar="treeNode" value="#{searchTreeProvider.rootNode}"
var="item" ajaxKeys="#{null}"
nodeFace="#{item.type}">


<rich:treeNode id="id1" type="type1" iconLeaf="icon1.png"
icon="icon1.png">
<h:outputText id="idd1" value="#{item}" />
</rich:treeNode>

 <rich:treeNode id="id2"
 type="type2" iconLeaf="icon2.png" icon="icon2.png">

<h:outputText id="idd2" value="#{item}" />
</rich:treeNode>

</rich:tree>

When running the App, the tree is rendered with it's first level nodes but with the default tree icons comming with RichFaces and when I click the node to expand, I get the following exception:

javax.servlet.ServletException: javax.el.PropertyNotFoundException: /portlet/view.xhtml @78,35 nodeFace="#{item.type}": Property 'type' not found on type org.richfaces.model.TreeNodeImpl

 org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:517)
 org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

as a root cause.

I read in one other forum a suggestion that one should use rather the var="item" property the treeNodeVar="item" property of the tree component.

I did it and it resulted with the same exception.

I will appreciate any suggestion or redirection to another thread with similar problem.

Thanx in advance
