link in richfaces tree menu

[safa]

Hi,
I work with jboss seam2.0.3 and richfaces;
I have a treemenu:

<rich:tree 
                                style="width:300px" 
                                rendred="true"
                                nodeSelectListener="#{menu1.processSelection}" 
                                reRender="selectedNode" 
                                switchType="client" 
                                value="#{menu1.treeNode}" 
                                ajaxKeys="#{null}"
                                ajaxSubmitSelection="true"
                                var="item">
                        </rich:tree>
        

it work very well, but I would like to be redirected to an other page when I click on a tree node,
Have any body any idea??

thx

<rich:tree ... var="item">
  <rich:treeNode>
     <h:outputLink value="#{item.text}" action="#{item.action}" />
  </rich:treeNode>  
</rich:tree>

and action is a normal jsf action with string outcome

class Item {
  public String action() {
     return "massive shouts"
  }
}

i think it should work,

PS: massive shouts is from www.bassdrive.com :)

Hi,

After adding the following call with URL link



public class NodeData {
   
        private String nodeText;

    private Boolean selected = Boolean.FALSE;
   
     
    private String url;
   
   
        public NodeData(String nodeText,String url) {
        this.nodeText = nodeText;
        this.url= url;
    }


         public String getUrl() {
                return url;
        }

        public void setUrl(String url) {
                this.url = url;
        }

        public String getAction(){
                        System.out.println(" This is called at least  "+this.url);
                return this.url;
        }

        public String getNodeText() {
                return nodeText;
        }

        public void setNodeText(String nodeText) {
                this.nodeText = nodeText;
        }

        public Boolean getSelected() {
                return selected;
        }
        public void setSelected(Boolean selected) {
                this.selected = selected;
        }

   
}

it throws following exception :

javax.servlet.ServletException: #{node.url}: javax.el.MethodNotFoundException: /provisioningTreeNew.jsp @37,90 action="#{node.url}": Method not found: [e-mail]()


Please let if implemented such example.

Thanks in advance

XHTML :

Add the below tag in your XHTML page

<rich:tree value="#{TreeBean.tree()}" var="node" switchType="client" rowKeyConverter="org.richfaces.TreeRowKeyConverter" nodeSelectListener="#{TreeBean.processNodeSelection}" ajaxSubmitSelection="true"  iconExpanded="true">
</rich:tree>


Backing Bean :
public TreeNodeImpl tree(){
        TreeNodeImpl<String> data = new TreeNodeImpl<String>();
          
        for (int i = 0; i < components.length; i++) {
             TreeNode<String> child = new TreeNodeImpl<String>();
             child.setData(components[i]);
             data.addChild(components[i], child);
            
             for (int j = 0; j < attributes[i].length; j++) {
                  TreeNode<String> grandChild = new TreeNodeImpl<String>();
                  grandChild.setData(attributes[i][j]);
                 
                  child.addChild(attributes[i][j], grandChild);
       
                  
             }
        }
        return data;


Add a Listener code in your backing bean which will redirect the page to the desired url:



private Object selectedNodeData;

          public String processNodeSelection(NodeSelectedEvent event) {
            HtmlTree tree = ((HtmlTree) event.getComponent());
           
            selectedNodeData = tree.getRowData();
           
            if(selectedNodeData.equals("Periods")){
                FacesContext context = FacesContext.getCurrentInstance();
                HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();
                try {
                                response.sendRedirect("/login.seam");
                        } catch (IOException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                        }

                return "/login.seam";
            }
                return null;
          }

          public Object getSelectedNodeData() {
            return selectedNodeData;
          }
