Myfaces t:tree2 component

Hi
Is there any way to get the all the nodes to a selected leaf?
Like instead of ((TreeNode)node).getDescription() returns the leaf. Is there a way to return the full path to that leaf?
Thank you in advance.

SenkaTatsujin: Have you figured this out?
If you have could you please share what you did.
Thanks,

JSF Tree construction - My Faces Tree2 Component development

Hi
I am planning to recommend JSF and MyFaces for the development of the application.
like Navigation Tree on the left side, header, footer and body ..
1) Can any one share a piece of code to develop Dynamic Navigation Tree(like ServerSideToggling ..I will get the data from backend based on the I will build the Tree with leafs, when we click on leafs we need to call action to redirect to other jsps ) we can achieve this using MyFaces Tree2 Component,Just wondering if anybody know some information, any info is appreciated.
Parent1
|
--Child1__
|--sub child 1
--Child2
--Child3
Parent2
|
--Child1__
|--sub child 1
--Child2
--Child3
Conditions:
1) Need to construct the Tree based on backend data.
2) All the Parents and Children should be links, like when I click on any link, I need to call an action and forward it some other page.
For testing I hardcoded and built one tree, which look similar...but the dynamic tree needs server side toggling..which requires...handling of backend data...constructing a tree...If you could share a sample, I will be appreciated...mean while I will try to do this...
thanks

HI jish,
A couple suggestions.
While the MyFaces (tomahawk) components may be very useful, I would encourage you to make sure you're using JSF from the Mojarra project. It is more stable and better supported: https://javaserverfaces.dev.java.net
Also, I would encourage you NOT to use JSPs. JSF 2.0 will favor a facelets-style syntax, so you should consider using Facelets or JSFTemplating instead. JSP is also slower and more cumbersome to work with. Try: https://jsftemplating.dev.java.net or https://facelets.dev.java.net . Either one of these projects replace JSP and provide "templating" support (which doesn't exist when using JSP) as well as many other features to help you (like JSFTemplating's factories for creating dynamic trees).
I don't use MyFaces Tree2 component (I use Woodstock's Tree component), however, I think the concepts should be the same. Here's some a link to a very complicated example (GlassFish Admin Console Tree code which is generated from several backend sources + updated via Ajax):
https://glassfish.dev.java.net/source/browse/glassfish/admin-gui/src/docroot/peTree.jsf?rev=1.12&view=markup
A more simple example:
<sun:tree text="Tree Example" clientSide="false" url="http://www.google.com">
    <sun:treeNode text="Static Tree Node" actionExpression="#{some.thing}">
        <dynamicTreeNode treeAdaptorClass="com.sun.enterprise.tools.admingui.tree.MBeanTreeAdaptor"
            objectName="com.sun.appserv:type=applications,category=config"
            methodName="getAllDeployedJ2EEApplications"
            text="Dynamic Tree Node"
            url="/applications/enterpriseApplications.jsf"
            attributeName="name"
            childURL="applications/enterpriseApplicationsEdit.jsf?appName=#{$this{valueBinding}.text}" />
    </sun:treeNode>
</sun:tree>Another place to look is the scales project. The lead developer on that project is actively developing a Tree component that will have a very clean interface to interacting with dynamic trees.
Good luck!

Tomahawk tree2 component using css

hi,
Is there any way to set new style (css) to Tomahawk tree2 component ?? Can you give me an example ?
best regards,

This question is apparently about JSF. This forum is not about JSF.
To find the correct forum here you have to know that "JSF" is an acronym for [JavaServer Faces|http://forums.sun.com/forum.jspa?forumID=427].

MyFaces' JspTilesViewHandlerImpl   &   dynamic component rendering

Hi,
First -- if you're on the myfaces user list, this is a repeat post. Skip!
Second, I don't mean to offend the RI dev guys with this myfaces post!
Has anyone dynamically rendered JSF components while using myfaces� JspTilesViewHandlerImpl view handler?
I have a WebGalileoFaces tabbed panel component. Its listener attaches sub-tabs to it dynamically. The rendering works without using the view handler above. Yet, when I use the myfaces handler, I get an NPE. My listener impl is below.
The view handler appears to cut off access to the actual UIViewRoot so the form cannot be found. I�ve tried a couple calls directly to the handler using context.getApplication().getViewHandler() yet, none of the methods gave me access to it (well, that I could figure out).
Ideas anyone?
Thanks
Lorinda
    public void processTabSelected(TabSelectedEvent event)
            throws AbortProcessingException {
        context = FacesContext.getCurrentInstance();
        // who sent the event?
        FacesTabbedPanel eventSource = (FacesTabbedPanel) event.getSource();
        UIComponent tabbedPanel = event.getComponent();
        String tabName = tabbedPanel.getId();
        String formId = tabbedPanel.getParent().getId();
        LOG.info("Tab selected:   " + tabName);
        LOG.info("Parent form:   " + formId);
     UIForm form = (UIForm) context.getViewRoot().findComponent(formId);
NPE HERE ---- UIPanel panel = (UIPanel) form.findComponent("childTabsGrid");
// NOTE: the childTabsGrid must be used to attach children.
        if (panel == null) {
            LOG.error("PanelGrid   'childTabsGrid'   could not be found. ");
        } else {
// ATTACH SUB TABS
            // clear the childTabsGrid to prevent stacking child tabs
            panel.getChildren().clear();
          ListSelectionModel selectionModel = eventSource.getListSelectionModel();
           UIComponent newTabbedPanel = createSubTabbedPanel(selectionModel);
           panel.getChildren().add(newTabbedPanel);
        }

Yes, i have created a complete portal page using a custom portal tab and JspTilesViewHandlerImpl with all components dynamically rendered and inserted by tiles: dynamic partal tabs, i18n implementation for mesages and SelectItems, dynamically change company layout with its own look-and-feel if a requested information belongs to a company (division, department, branch office, etc). There is some abnormality and how i go around to get the solution up and running. I will post the details in myfaces dev list in the next couple days.
In essence, the navigation page dispatched by JspTilesViewHandlerImpl works properly with all Jsf UI components. However, within this tile definition and its own layout, any fragment inserted by tiles such as portlets in the left/right columns and the display fragment does not have jsf <h:commandButton> and <h:commandLink> correctly picked up the action while <h:outputLink> properly linked to the intended page.
I temporarily solve the issue to get the portal up and running. However, this is only a temporary solution since it will severly limit a complete integration of Jsf+Tiles. A complete solution needs to be addressed, which i thing myfaces developers can quickly patch it.

MyFaces Tomahawk more than one tree2

Hi everybody, I'm new with JSP and I'll appreciate some help with this:
I have a JSP app implementing MyFaces Tomahawk tree2 with TreeBacker class modified, the component renders pretty well, but I need to show another tree completely different, I made a new class almost equal than TreeBacker but the name and the new tree structure, but at runtime the tree doesn't renders.
In the running tree2:
<t:tree2 id="clientTree" value="#{treeBacker.treeData}" var="node" varNodeToggler="t" clientSideToggle="true">Additionaly, why if I change treeBacker.treeData to TreeBacker.treeData the tree2 doesn't renders ??
In the rebel tree2:
<t:tree2 id="clientTree" value="#{treeBacker2.treeData}" var="node" varNodeToggler="t" clientSideToggle="true">this tree2 doesn't work....
What I'm doing wrong ?

I don't understand very good who works the repeater that you put there. And in the dataprovider I have to know how many trees I will have? Because I don't know how many trees I will have(in one moment 1, later 4, later 2... I could put a variable but I don't understand very good how can I do the repeater and..).
I get create a dinamic Vbox with X tress, but putting all the xml in one, something like this:
<?xml version="1.0" encoding="UTF-8"?>
<Cuentas>
    <Cuenta id="cuenta1" label="cuenta1">
    <node label="INBOX">
        <node label="Nombre">
    </node>
    </node>
    </Cuenta>
    <Cuenta id="cuenta2" label="cuenta2">
    <node label="INBOX">
        <node label="Apellido">
    </node>
    </node>
    </Cuenta>
</Cuentas>
With my treeLoad code I create 2 tress in one Vbox, if the xml document have 3 diferents Cuenta I will create 3 trees. But now I have different xml and I don't how can I do the same.

MyFaces Tree Component Rendering

Hi all,
I am adding myfaces client tree Component to my panel.Its not rendering and its throwing exception.
anyhelp would be appriciated
Thanks
Sudha

Hi,
I am trying to render myfaces client tree on faces portlet using RAD 6.0. As RAD does not support JSF 1.1, I have commented DOCTYPE from faces-config.xml in tomahawk.jar file.
Root of the tree is getting displayed without "+" sign. And when I click on it,
javascript error "Object Expected" occurs.
I am not able to figure out the problem from last 2 days. So, Please help me out if you can.
Thanks in anticipation.

Tree2 in Tomahawk and JSF Tiles Implementation

hi All,
right now i mfacing one problem. which arise due to tiles implementation in JSF with Tree2 component of Tomahawk. i had created one tree menu using Tree2.
its working fine, but i was not able to highlight selected child node of tree menu as i m using tiles implementation so all pages gets reloaded on every click on jsp. thus color of that selected node becomes as it is.
please note that i m using myfaces implementation.
what i have written is as below:
<t:tree2 id="wrapTree" value="#{frontPage.catTree}" var="node" clientSideToggle="true"
                         showRootNode="false" varNodeToggler="t">

please help me if u have solution of this problem.
thank you.

hi,
in MyFaces there is an example using JSF and Tiles.
MyFaces provides a custom ViewHandler faciltity.

Richfaces is compatible with JSF 1.1 and 1.2 and also with great ui part
but it may conflict with the other tomahawk component and filters

Tree2 leaf selection

I am trying implement myfaces tree2 component. Here the tree list files in filesystem and what i am trying to do is on selection of a leaf in the tree, set the InputText tag fileName.
How do i do this ?
This is how my jsf code action class look
file.jsp
          <h:inputText id="fileName" value="#{fileAction.fileName}" />
          <t:tree2 id="clientTree2" value="#{fileAction.fileList}"
               var="node" varNodeToggler="t" showRootNode="false" clientSideToggle="false">
               <f:facet name="document">
                    <h:panelGroup>
                         <h:commandLink immediate="true"
                              styleClass="#{t.nodeSelected ? 'documentSelected':'document'}"
                              action="#{fileAction.doSetFileName}">
                              <t:graphicImage value="images/document.png" border="0" />
                              <h:outputText value="#{node.description}" />
                              <f:param name="fileName" value="#{node.description}" />
                         </h:commandLink>
                    </h:panelGroup>
               </f:facet>
          </t:tree2>
public class FileAction {
     private String fileName;
}

Hi
I think what you're going to need to do is to put a
valueChangeListener in your outputText node
<h:outputText value="#{node.description}"
valueChangeListener="#{<YOURBean>.processValueChange}
onclick="submit()" />
you will need the onclick as well otherwise you don't
get the event firing until the node has lost
focus/page submit
In you bean code you will need to have a method -
along the lines of
public void processValueChange(ValueChangeEvent
event) throws
AbortProcessingException {
UIComponent component = event.getComponent();
UIOutput outPutText = (UIOutput)component;
FacesContext fC =
= FacesContext.getCurrentInstance();
UIViewRoot root = fC.getViewRoot();
UIComponent c = root.findComponent("fileName"); //
// the id of your
inputText field
if(c != null){
UIInput fileName = (UIInput)c;
fileName.setValue((String)outPutText.getValue());
//     Now update GUI
fC.renderResponse();
NOTEs
the above code is for example purposes only - you
will need to tailor it for safe operation within your
app
You may NOT need the renderresponse call - this
causes an immediate screen re-darw and the screen
does NOT necessarily scroll to where you left it<h:outputText value="#{node.description}"
valueChangeListener="#{<YOURBean>.processValueChange}"
onclick="submit()" />
I am doubt of this. can outputText attribute be valueChangeListener?

A tree component

Hello,
I'm presently looking for a JSF tree component. I need one which not only would allow me to display a little icon next to my leaves names, but which would allow me to display a checkbox too.
I've tried the Apache MyFaces tree, in the Tomahawk sub-project. But it looks like I won't manage to add a checkbox without changing its code.
A clue, anyone ? With MyFaces or anything else ?

Tree2

I am trying to use the tree2 component that ships with MyFaces Tomahawk but I keep running into issues. I've been trying to debug this for two days now.
I have gotten the tree2.jsp example up and running but it breaks when i try to customize it. It keeps giving me the error
Encountered a node [0:0:1] + with an illogical state. Node is expanded but it is also considered a leaf (a leaf cannot be considered expanded.The code works fine if I my TreeBacker.getTreeData() looks like this:
public TreeNode getTreeData()
     TreeNode treeData = new TreeNodeBase("foo-folder", "Inbox", false);
     TreeNodeBase personNode = new TreeNodeBase("foo-folder", "Frank Foo", false);
     personNode.getChildren().add(new TreeNodeBase("document", "C050003", true));
     treeData.getChildren().add(personNode);
        return treeData;
    }However if I add one more node beneath that (which is explicitly marked as a leaf) it bombs out on me with the error mentioned above:
public TreeNode getTreeData()
     TreeNode treeData = new TreeNodeBase("foo-folder", "Inbox", false);
     TreeNodeBase personNode = new TreeNodeBase("foo-folder", "Frank Foo", false);
     personNode.getChildren().add(new TreeNodeBase("document", "C050003", true));
     personNode.getChildren().add(new TreeNodeBase("document", "22C050003", true));
     treeData.getChildren().add(personNode);
        return treeData;
    }

My best guess would be that the nodes that have not been expanded don't actually exist in the HTML. So they cannot send data back to the server. You may want to implement server-side logic to handle this case.

About af:tree component

......... I use JDeveloper 11g TP4 .............
I use tree component to desplay a recursion relationship as the relation between Employee and Manager in HR schema (Manager is an Employee)
I want the tree to desplay manager and it's employee as Children and Children(a manager to another employee) may have a subchildren and so on.
I make a tree and it desplay the data correctly but I want when I press to any node I show the data of its child in a table. the problem when I press to any node it return the id of the first node (root) I want when I press a child it return its Id not The root Id.
tree code:
<af:tree value="#{bindings.EmployeesView1.treeModel}" var="node"
selectionListener="#{bindings.EmployeesView1.treeModel.makeCurrent}"
rowSelection="single" binding="#{backing_untitled1.tree1}"
id="tree1">
<f:facet name="nodeStamp">
<af:outputText value="#{node}"
binding="#{backing_untitled1.outputText1}"
id="outputText1"/>
</f:facet>
</af:tree>
I construct it from wizerd I did not write any code.....
Thank You

I have the same problem in the <t:tree2> component. If any clues, please let us know.

Tomahawk tree2 not rendered properly in mobile browser

Hi,
I was trying to use tomahawk tree2 component. It was able to render properly on the desktop browser.
I tried to open the same application on the PDA IE browser. There is a gap between the nodes.
It was not looking good.
How can i apply my own styles to overcome the problem.
Thanks in Advance
Sur

Report this issue at the mailinglist/issuetracker of Tomahawk. You see, you're here at a Sun forum, not at an Apache forum.
