Highlight an ADF tree node when it is clicked

Hello every onei ,
Does anybody has any idea how to highlight an ADF tree node when it is clicked ?
Here is my scenario:-
I have a popup which has a tree component on left and when we click on any node in the tree we have to display the corresponding page on right side.
As the tree is common for all pages in the popup, i created an XHTML template with tree. All the treenode pages will use this template to display the tree.This template i am using to implement in rest of the pages.
So when i click any link on this tree will load the corresponding JSP. But i am loosing focus. i mean selected node is not highlighting. Because we are loading the entire target page with template.
Could any let me know how to highlight the tree node ?
The Main problem is we are not using ADF controllers. We are using managed beans, these managed beans attached to the JSPX pages.
Kindly guide me if any one knows solution.
Thanks & Regards,
Sai Sravan.P

Hello Sai,
I am afraid you have posted your question in the wrong forum. This forum is about Oracle On Track Communication, a next-generation social enterprise collaboration product.
Please re-post your question in an ADF related forum and I am sure someone will be able to answer.
Thank you,
Ernst.

  • Af:tree - how do I highlight the selected tree node?

    af:tree
    I checked the generated CSS file. I found that when a tree node is selected, the related CSS attribute is:
    .xj:link{
    font-family:Arial,Helvetica,Geneva,sans-serif;
    font-size:10pt;
    font-weight:normal;
    color:#663300
    I created a customized CSS attribute, but then all of the links have the customized CSS attributes.
    How do I just highlight the selected tree node link?
    Thanks,

    try doing the onclick javascript method
    you have to place it on the node element and id must be made dynamic
    for this use 'this.id'
    by which the current id of the node is passed
    and by capturing the id name in a var
    use the same for invoking its selected property and make it true
    like this
    var currentid = this.id;
    this.form.currentid.selected = true;

  • Highlight the selected Tree Node

    Hello Everyone,
    Can someone plz tell me how to highlight the selected tree node ?
    After selection, user should be able to see which node was last selected.
    Thanks

    Hello,
    for me it is not really clear what you have done. Sorry!
    Because I have problems to paste code, I will describe how you can test that function.
    Take the BSP application HTMLB_SAMPLES and copy it to ZHTMLB_SAMPLES. Take page "treeviewSample.htm" and add the following node behind node22:
    <htmlb:treeNode id   = "node23"
                      text = "Node 2.2, normal text"
                      selection="PRIMARYSELECTION">
    Perhaps this will show you how it works and help you.
    As far as I can see the attribute "selection" can't be set via table.
    Best regads

  • Programmatically getting ADF Tree node value(Version 11.1.2.0.0)

    Hi Forum,
    My Jdeveloper version 11.1.2.0.0
    and i am using Fusion Web Application (ADF) Template.
    In my .jspx page i have added ADF Tree.
    Now i want to get node value from backing bean.
    My java code is
    public void selectevent(SelectionEvent evt) {
    RichTree tree = (RichTree)evt.getSource();
    TreeModel model = (TreeModel)tree.getValue();
    RowKeySet rowKeySet = evt.getAddedSet();
    Object key = rowKeySet.iterator().next();
    model.setRowKey(key);
    JUCtrlValueBinding nodeBinding = (JUCtrlValueBinding)model.getRowData();
    if(model.getDepth()==1){
    int empid = (Integer)nodeBinding.getAttribute("EmployeeId");
    when i click on second node the following error occured.

  • Displaying the entire text of a tree node when the tree isn�t wide enough

    Hi,
    I have a JTree displayed in a JScrollPane, so there is a chance that some of the tree data may be hidden if the tree's width is insufficient, so when the user moves the cursor over a tree node whose text is not completely visible (cut off by the right edge of the scroll pane and/or window), a tooltip is displayed to show the entire node text. So far so good!
    If the user double click a node in the tree a new window is supposed to be opened. This works fine if the tooltip hasn�t been displayed jet, but if it has then the user has to click 3 times to open the window.
    The first time to remove the tooltip and the next 2 opens the window.
    How can I awoid this?
    Thanks!!!!
    :-)Lisa

    Any ideas, please?

  • Formatting multiple values in ADF tree node

    JDeveloper 11.1.2.2.0 -- WinXP
    I have an ADF tree component that is bound to a table with two values per node level.
    The results look like:
    Fruit 1234
        -- VineGrown 5678
           -- Grapes 4567
               -- Red 1234
               -- Green 56
    Veggie 4567
       -- Root 45
          -- Carrot 34
          -- Potato 987What I want to be able to do is format the outputText so that it will end up looking more like "Fruit :: Total 1234"
    The issue is that the EL of #{node} displays both the node level value and the number as one item. This is in the facet nodeStamp.
    If I try and get more specific with the EL, I can separate out the Uses number by doing #{node.Uses} but I can't get the node name to still be dynamic for each level.
    My binding options for node are shown as:
    node.Type
    node.GrownLocation
    node.Group
    node.Value
    node.Uses
    Of course setting the first #{node} to any of these more specific values doesn't display at all for the node levels that don't correspond to just that one level.
    Ideally the EL line would look something like:
    <af:outputText value="#{node.name} ::  Total: #{node.Uses}" id="ot3"/>where node.name could be any one of the levels: Type, GrownLocation, Group, etc.
    Is this something that pathStamp would be used for? I couldn't really figure out how pathStamp worked from the docs.
    Thanks for any help. Hopefully this makes some sense.

    You can try something like this:
    <af:column id="c1">
    <af:outputText value="#{node.name} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.name != null}"/>
    <af:outputText value="#{node.Type} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.Type!= null}"/>
    <af:outputText value="#{node.GrownLocation} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.GrownLocation!= null}"/>
    <af:outputText value="#{node.Group} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.Group!= null}"/>
    </af:column>So the rendered property will make sure that the correct node is displayed according to each level.
    Hope this helps.

  • ADF Tree Nodes Undisclose...

    Hi !. I have the following question about expanding or collapsing nodes...
    I have my own class ("NodoMapaDeSitio") that I use as my items to render my tree; so, the method "getRowData" returns an instance of "NodoMapDeSitio". Every time I click a node, the "varStatus.rowKey" returns me something like this:
    [0]
    [1]
    or
    if I press ina subNode [1,0] [1,1]...
    My question would be if it's possible to make integer vectors to build the children key's of a node in order to disclose them or undisclose them ?.
    In case that, that is possible, the following method ".setDisplayRowKey" would help me to expand certain nodes... But which method would help me to callapse them ?.
    Well Hope I was clear... Thankx

    Hi Timo... I solved it this way... I use the varStatus to obtain the key of the node which I pressed and I checked if that key is inside the discloseRowKeySet; if it is, I remove and collapse it !. The code is as follows...
    ArrayList lista = (ArrayList) this.objeto;
    RowKeySet rowKeySet = arbol.getDisclosedRowKeys();
    if(rowKeySet.contains(lista))
    rowKeySet.remove(lista);
    else
    rowKeySet.add(lista);
    AdfFacesContext.getCurrentInstance().addPartialTarget(this.arbol);
    AdfFacesContext.getCurrentInstance().partialUpdateNotify(this.arbol);

  • How can I get the adf-tree-node's attributes?

    I want get the attributes in the method of "selectionListener"?
    How can I do?
    I only know :
    RichTree treeId;
    RowKeySet keySet = treeId.getSelectedRowKeys();
    Thanks!

    You don't want to maintain a reference to the last selected node, but to the last selected path. Nodes within a tree are addressed using a TreePath, with contains references to each node from the root, down to a specific node. Look at the JavaDocs of javax.swing.tree.TreePath for more info.
    Also, JTree has getter/setter methods for the selectionPath.

  • Tree and Tree Node Components - Threadinar7

    Hi All,
    This is the seventh in the "Threadinar" series , please see Threadinar6 at
    http://forum.sun.com/jive/thread.jspa?threadID=100601 for details
    In this Threadinar we will focus on the
    "Tree" and "Tree Node" Components
    Let us begin our discussion with the Tree Component.
    Tree Component
    You can drag the Tree component from the Palette's Basic category to the Visual Designer to create a hierarchical tree structure with nodes that can be expanded and collapsed, like the nodes in the Outline window. When the user clicks a node, the row will be highlighted. A tree is often used as a navigation mechanism.
    A tree contains Tree Node components, which act like hyperlinks. You can use a Tree Node to navigate to another page by setting its url property. You can also use a Tree Node to submit the current page. If the the Tree Node's action property is bound to an action event handler, selecting the node automatically submits the page. If the Tree Node's actionListener property is bound to an action listener, opening or closing the node automatically submits the page. You set Tree Node properties in the Tree Node Component Properties window.
    * If you use this component to navigate between pages of a portlet, do not use the url property to link to a page. Instead, use the Navigation editor to set up your links to pages.
    * Events related to tree node selection do not work correctly in portlets because the component uses cookies to pass the selected node id back and forth, and cookies are not correctly handled by the portlet container. You cannot handle tree node selection events in portlet projects.
    Initially when you drop a tree on a page, it has one root node labeled Tree and one subnode labeled Tree Node 1. You can add more nodes by dragging them to the tree and dropping them either on the root node to create top level nodes or on existing nodes to create subnodes of those nodes. You can also right-click the Tree or any Tree Node and choose Add Tree Node to add a subnode to the node.
    Additionally, you can work with the component in the Outline window, where the component and its child components are available as nodes. You can move a node from level to level easily in the Outline window, so you might want to work there if you are rearranging nodes. You can also add and delete tree nodes in the Outline window, just as in the Visual Designer.
    The Tree component has properties that, among other things, enable you change the root node's displayed text, change the appearance of the text, specify if expanding or collapsing a node requires a trip to the server, and specify whether node selection should automatically open or close the tree. To set the Tree's properties, select the Tree component in your page and use the Tree Component Properties window.
    The following Tutorial ("Using Tree Component") is very useful to learn using Tree components
    http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/sitemaptree.html
    See Also the Technical Article - "Working with the Tree Component and Tree Node Actions"
    http://developers.sun.com/prodtech/javatools/jscreator/reference/techart/2/tree_component.html
    Tree Node Component
    You can drag the Tree Node component from the Palette's Basic category to a Tree component or another tree node in the Visual Designer to create a node in a hierarchical tree structure, similar to the tree you see in the Outline window.
    The tree node is created as a subnode of the node on which you drop it. If you drop the node on the tree component itself, a new node is created as a child of the root node. You can see the hierarchical structure clearly in the Outline window, where you can also easily move nodes around and reparent them.
    You can also add a tree node either to a Tree component or to a Tree Node component by right-clicking the component and choosing Add Tree Node.
    A Tree Node component by default is a container for an image and can be used to navigate to another page, submit the current page, or simply open or close the node if the node has child nodes.
    * If you select the Tree Node component's node Tree Node icon in the Outline window, you can edit its properties in the Tree Node Properties window. You can set things like whether or not the Tree Node is expanded by default, the tooltip for the Tree Node, the label for the tree node, and the Tree Node's identifier in your web application.
    * You can use a Tree Node to navigate to another page by setting its url property. You can also use a Tree Node to submit the current page. If the the Tree Node's action property is bound to an action event handler, selecting the node automatically submits the page. If the Tree Node's actionListener property is bound to an action listener, opening or closing the node automatically submits the page.
    - Note: If you use this component to navigate between pages of a portlet, do not use the url property to link to a page. Instead, use the Navigation editor to set up your links to pages. In addition, events related to tree node selection do not work correctly in portlets because the component uses cookies to pass the selected node id back and forth, and cookies are not correctly handled by the portlet container. You cannot handle tree node selection events in portlet projects.
    * If you select the image in the Tree Node, you can see that its icon property is set to TREE_DOCUMENT. If you right-click the image on the page and choose Set Image, you can either change the icon to another one or choose your own image in the Image Customizer dialog box. For more information on working with an image in a tree node, see Image component.
    - Note: The image used in a tree node works best if it is 16x16 or smaller. Larger images can work, but might appear overlapped in the Visual Designer. You can right-click the component and choose Preview in Browser feature to check the appearance of the images.
    Please share your comments, experiences, additional information, questions, feedback, etc. on these components.
    ------------------------------------------------------------------------------- --------------------

    One challenge I had experience was to make the tree
    always expanded on all pages (I placed my tree menu
    in a page fragment so I can just import it in my
    pages).Did you solve this problem. It would be interesting to know what you did.
    To expand a node you call setExpanded on the node. Here is some code from a tutorial that a coworker of mine is working on.
    In the prerender method:
           Integer expandedPersonId = getRequestBean1().getPersonId();
             // If expandedPersonId is null, then we are not coming back
            // from the Trip page. In that case we do not want any trip
            // nodes to be pre-selected (highlighted) due to browser cookies.
            if (expandedPersonId==null) {
                try {
                    HttpServletRequest req =(HttpServletRequest)
                    getExternalContext().getRequest();
                    Cookie[] cookies = req.getCookies();
                    //Check if cookies are set
                    if (cookies != null) {
                        for (int loop =0; loop < cookies.length; loop++) {
                            if (cookies[loop].getName().equals
                                    ("form1:displayTree-hi")) {
                                cookies[loop].setMaxAge(0);
                                HttpServletResponse response =(HttpServletResponse)
                                getExternalContext().getResponse();
                                response.addCookie(cookies[loop]);
                } catch (Exception e) {
                    error("Failure trying to clear highlighting of selected node:" +
                            e.getMessage());
            }                  ... (in a loop for tree nodes)...
                      personNode.setExpanded(newPersonId.equals
                                    (expandedPersonId));In the action method for the nodes:
           // Get the client id of the currently selected tree node
            String clientId = displayTree.getCookieSelectedTreeNode();
            // Extract component id from the client id
            String nodeId = clientId.substring(clientId.lastIndexOf(":")+1);
            // Find the tree node component with the given id
            TreeNode selectedNode =
                    (TreeNode) this.getForm1().findComponentById(nodeId);
            try {
                // Node's id property is composed of "trip" plus the trip id
                // Extract the trip id and save it for the next page
                Integer tripId = Integer.valueOf(selectedNode.getId().substring(4));
                getRequestBean1().setTripId(tripId);
            } catch (Exception e) {
                error("Can't convert node id to Integer: " +
                        selectedNode.getId().substring(4));
                return null;
    It would also be great if I can set the tree
    readonly where the user cannot toggle the expand
    property of the tree (hope this can be added to the
    tree functionality).

  • Best approach -Tabs based ADF Tree left side navigation with Dynamic Regions with out UI Shell

    Hi,
    Somebody can help for the best approach to implement the following requirement.
    Req: When the user select the ADF Tree left side navigation menu, each menu will open as multiple tabs(Dynamic Tabs) in right side content area with out UI Shell Template.
    I completed the
    Step-1: From the Model project, I can able to render ADF Tree in the using view and view links. I can get the adf tree which is having 3 menu items. Each menu item having 2 sub menu's.
    I took each menu item as one(1) taskflow, each taskflow will have two(2) fragments.
    Total I have 3 task flows as Menu Items and 6 fragments for sub menu's.
    Step-2:  My question is How do I implement Tab based the ADF tree navigation (left side area to dynamic regions in content area) through dynamic regions? Please provide the steps in view layers.

    Than ks for your response.
    This is working fine for ADF Tree navigation with dynamic regions if the taskflow having only one fragment. if the taskflow having more than one fragments, this will not work. The following conditions are always satisfies one page fragment of either "employees" or "departments" task flow.  If the "employees" task flow have 2 page fragments, it's not work even you pass parameters through routers.
    public TaskFlowId getDynamicTaskFlowId() {
    if (currentTaskFlowID == null ||
    currentTaskFlowID.equalsIgnoreCase(“employees”)) {
    return TaskFlowId.parse(employeetaskFlowId);
    if (currentTaskFlowID != null &&
    currentTaskFlowID.equalsIgnoreCase(“departments”)) {
    return TaskFlowId.parse(departmetaskFlowId);
    return TaskFlowId.parse(employeetaskFlowId);
    My question is "Same use case with Dynamic Tabs" when the user click on any adf tree node.

  • Quick Info on ALV Tree node

    Hi All,
    I have this requirement.
    On ALV Tree node, when user places cursor then i should display some text as quick info.
    while create node i have used ICON &lt;- left arrow, i cannot use other ICOn as functional person need this icon only.
    During Add_Node, if I pass icon through node layout then its showing nothing, Instead if I pass icon through item layout, then its showing SAP standard ICON text left arrow , but i need custom text write text  there.
    I tried using Context_menu_req as well, even that didnt worked. Any ideas/views will be highly appreciated.
    Thanks n Regards

    Hi Mr A.
    You can try the following:
    DATA: l_node_text TYPE lvc_value.
    DATA: ls_item_layo TYPE lvc_s_layi,
                 lt_item_layo TYPE lvc_t_layi.
            l_node_text             = 'UR Text'
            ls_item_layo-style      = gs_detail-color_code.
            ls_item_layo-t_image    = gs_detail-icon.
            APPEND ls_item_layo TO lt_item_layo.
    After the above mentioned statement, you may call 'Add Node' method of ALV Tree.
