Command link used as tree node

I'm using an ADF Tree where one of my nodes is a command link. I've given the link an id="myLink".
When I run the page, the tree shows up fine with just one node.
But the View Page source does not contain any entry that says id="mylink".
Where could be the problem?
Thanks

Hi,
I assume you use ADF Faces RC, because otherwise you would have posted this to the JDeveloper forum. If you add a command link t a node, then this command link is used for any node that is rendered for the tree (unless you implemented it in a way that only has exactly one command link component showing in the whole tree - which I don't think you have).
In JSF you cannot have more than one component with a specific ID, which means that assigning an ID to a command link in a tree doesn't make much sense.
In ADF Faces RC, trees are active components, which means they are created in the DOM and not HTML. So using a DOM inspector like Firebug you should see your tree and link components
<a id="j_id___jsp_tag_ctru4:7:myLink" class="xdk" href="#" onclick="return false;">commandLink 1</a>

Programatically adding command links in ADF Tree?

Hi,
I am using Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660. Can anyone please provide me some sample code for programatically adding dynamically generated ADF command links in the nodes of ADF Tree(Tree nodes in it are created using View Object - Drag & drop of data control). Now how can i add links in the nodes generated.
Thanks,
Vik

Hi,
try setting partialSubmit=true on the command link. Just in case it fires the action method before the context menu displays

Searching Hierarchical tree using Find tree node

In hierarchical tree using find_tree_node when i search the value it is taking the search value as a string and returns the node that of previous node value. for example
Suppose when i am searching for node value 18 ,but it takes the some other node value of (1883).
The tree structure is
1
2
1883
3
18
The code used is
p_node := ftree.get_tree_node_property ('tree_block.tree',:system.trigger_node,ftree.node_value);
current_node := Ftree.Find_Tree_Node(htree,
     p_node,
     Ftree.FIND_NEXT,
     Ftree.NODE_VALUE,
     Ftree.ROOT_NODE,
          Ftree.ROOT_NODE);

Hi!
You can use your restricting subquery in a start with clause. Something like
start with node_parent is null and some_field in (select ...)
Or you can eliminate the join and use where clause.
Hope this helps.

Action Event Handler on Tree nodes

I have an actionListener event handler registered on a tree node as follows:
<af:tree value="#{bindings.SomeViewObj1.treeModel}" var="node" rowSelection="none" id="t1"
binding="#{EditFormBean.tree1}" displayRow="selected" summary="Tree"
partialTriggers=":::cb1 :::cb2">
<f:facet name="nodeStamp">
<af:panelGroupLayout id="pgl3">
<af:outputText value="#{node}" id="ot1"/>
<af:commandImageLink text="E" id="cil3" partialSubmit="true"
*actionListener="#{EditFormBean.onEdit}"* binding="#{EditFormBean.cmdImageLink}">
<af:setPropertyListener from="#{node.hiertType.structureDefName}" type="action"
to="#{viewScope.formView}"/>
<f:attribute name="node" value="#{node}"/>
</af:commandImageLink>
<af:commandImageLink text="A" id="cil1"/>
<af:commandImageLink text="D" id="cil2"/>
</af:panelGroupLayout>
</f:facet>
</af:tree>
I have at each node stamp facet a panelGroup Layout that contains the node value and a command Image link. The tree has two hierarchical levels. When I press the command Image link on the first tree noe level, the actioListener method in teh managed bean (EditFormBean.onEdit) gets called. When I press the same commandImage link on the second tree level, the same action listener does not get called. I need to get past this problem before I code the actionListener which needs to set the current row in the iterator based on the key selected on the tree node. I simply have a print statement in the action listener method which shows something when the first level command image link is clicked but does not print anything when the second level command image link is clicked.
I am using JDeveloper 11.1.2.1.0
There is also adf faces code around this snippet that uses an af:switcher facea component to display the appropriate form based on the nodee level in which the comman d image link is clicled but it is irrelevant to the problem I am getting.
Any help on that would be appreciated

Hi,
hard to say . Didn't see this before. Can yoiu remove "binding="#{EditFormBean.cmdImageLink}"" from the command link. The tree stamps its children so that it doesn't make sense to keep a handle to the component instance

How to display a search(query) on a report clicking on a tree node to open

I need to know how can I do with that when I press on the link(on a tree node(leaf)), open on the other region in the same page a classic or interactive report with my results(passed by parameter, example: ID).
One example are present on web site posted below:
http://apex.oracle.com/pls/apex/f?p=36648:34:1599336964673301::NO:::
I have tried this to composite my tree:
select case when connect_by_isleaf = 1 then 0 when level = 1 then 1 else -1 end as status, level, "NAME" as title, null as icon, "ID" as value, null as tooltip, decode(level, 1, 'f?p=&APP_ID.:106:'||:APP_SESSION||'::::P106_MAQ_ID:'||ID, 2,'f?p=&APP_ID.:106:'||:APP_SESSION||'::::::::P106_MAQ_ID:'||(ID-1000), 3,'f?p=&APP_ID.:104:'||:APP_SESSION||'::::P106_MAQ_ID:'||(ID-10000), 4,'f?p=&APP_ID.:105:'||:APP_SESSION||'::::P106_MAQ_ID:'||(ID-100000)) as link from "#OWNER#"."V_TREE1" start with "PID" is null connect by prior "ID" = "PID" order siblings by "NAME"
But the parameter passed dont do with the report change your view to the one row with ID passed. I need to obtain the same results showed on website posted above.
I obtained success on action to redirect to other page with Form with Report to edit, but dont to show. And i want to show and the same page.
below the code that i obtained to redirect:
select case when connect_by_isleaf = 1 then 0 when level = 1 then 1 else -1 end as status, level, "NAME" as title, null as icon, "ID" as value, null as tooltip, decode(level, 1, 'f?p=&APP_ID.:102:'||:APP_SESSION||'::::P102_MAQ_ID:'||ID, 2,'f?p=&APP_ID.:103:'||:APP_SESSION||'::::P103_SRV_ID:'||(ID-1000), 3,'f?p=&APP_ID.:104:'||:APP_SESSION||'::::P104_INS_ID:'||(ID-10000), 4,'f?p=&APP_ID.:105:'||:APP_SESSION||'::::P105_SIS_ID:'||(ID-100000)) as link from "#OWNER#"."V_TREE1" start with "PID" is null connect by prior "ID" = "PID" order siblings by "NAME"
Thank you so much for your help.

Muhammad,
you can add a user parameter (p_count), which get the default value value 1 for example. Then add a field (with some source of type character like desname) for your footer with a format trigger like
if :p_count=1 then
     srw.set_field_char(0,'Office Copy');
elsif :p_count=2 then
     srw.set_field_char(0,'Shop Copy');
else
     srw.set_field_char(0,'Account Dept Copy');
end;
return true;
Or you build 3 boilerplates with format triggers like
if :p_count=1 then return true; else return false; end if; for "Office Copy" .....
In the After Report Trigger start the Report with same paramters using a higher value for p_count as parameter. If p_count=3, do nothing in the trigger.

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).

How do I enable the button to use the tree list in excel? (Enable the list type: Tree enabled in Office 2013 - VSTF 2013)

Hi, I was looking to see if anyone knows how I can troubleshoot my connection problem with TFS view in excel. I'm trying to produce a tree view in Office 2013 as described in the following KB -
https://msdn.microsoft.com/en-us/library/dd286627.aspx
I have followed the instructions on the KB all the way up to : 'Add backlog items and tasks and their parent-child links using a tree list' and at this point I can't seem to get it to work as the button is greyed out.
Note that I have completed steps 1-6 for the previous procedure... all 6 steps work just fine. However on step 2 of the second procedure - the instructions state I should be able to 'Add Tree Level' - However the button is greyed out.
Anyone know what I need to do to enable the button to use the tree list in excel?
Frank

Frank,
I believe your issue is that you have opened a Flat query and are trying to add tree levels. A flat query is just that and you cannot change the query type from Excel.
The second process is managing a backlog (which is a tree). TFS web access has a link on the backlog view to create a query. That query will be a "tree of work items" query that returns the items in the backlog including their parent-child relationships.
This type of query supports the Add Tree Level and Add Child functionality as does a new Input List (not bound to an existing query).

Display tree node data in bold characters

Hi,
I have a requirement where I need to display tree nodes data in bold characters. If I click on a particular tree node, next time it should appear in normal font only which means that some task had done using that tree node. Is my question clear??
Plz help me....
thanks,
ravindra.

Hi Ravindra,
I think it is possible, i have not done it but let me explain how we can do it.
In <htmlb:treeNode> tag there is an attribute 'text' in
which we specify title of that treeNode.
Now you define a page attribute 'treeNodeTitle' type
edpline and in onCreate assign it value <html><b>MyTreeNode</b></html>
When you click on this node then you do event handling
in onInputProcessing, there assign only 'MyTreeNode' to
treeNodeTitle.
sample code may look like this...
<htmlb:treeNode
id = 'treeNode1'
text = '<%=treeNodeTitle %>' >
</htmlb:treeNode>
Page Attribute
treeNodeTitle type edpline
in onCreate
treeNodeTitle = '<html><b>MyTreeNode</b></html>'
in onInputProcessing
in event-handling code for that treeNode write
treeNodeTitle = 'MyTreeNode'
I hope this will work.

Narinder Hartala

Getting selected row for command link in af:table

Hi
I have a h:commandLink in a column of my af:table. When it is clicked, I need to get the selected row data.
I know the documentation says use setCurrentRowValue method, but I am not using the Data Control Palette - I get the data fromt the database using code in the BackingBean.
Is there any other way? Pls help.

Yes, I got it. But my method gets the data in the selected row, not the rowKey
First I used af:commandLink instead of h:commandLink and then used af:setActionListener based on an example in the jDeveloper Help. I had to change it a bit since I am not using DCP or bindings.
This is the sample from Help, hope it helps!
SF Page Code for a Command Link Using a setActionListener Component <af:commandLink actionListener="#{bindings.setCurrentRowWithKey.execute}"
action="edit"
text="#{row.svrId}"
disabled="#{!bindings.setCurrentRowWithKey.enabled}"
id="commandLink1">
<af:setActionListener from="#{row.svrId}"
to="#{userState.currentSvrId}">
</af:commandLink>

How to pass parameter onclick of a command link created in a managed bean

Hi,
I created a command link in a managed bean using RichCommandLink . I want to pass a parameter on click of the command link like we do using <f:attribute> on the jspx. As i have created a command link using the bean hence i want to pass it programmatically to another method . How should i pass the parameter via the command link. Please help..

Hi,
can you please elaborate more on this.
i am not getting what you are trying to tell.
following is my actual code in java bean : :
RichCommandLink remove= new RichCommandLink();
remove.setId("E"+(rowID-1));
remove.setText("Remove");
FacesContext context = FacesContext.getCurrentInstance();
MethodExpression actionListener = context.getApplication().getExpressionFactory().createMethodExpression(context.getELContext(), "#{viewScope.test.onRemove}", null, new Class[] {ActionEvent.class});
remove.addActionListener(new MethodExpressionActionListener(actionListener));
childrenOfGroupLayout.add(remove);
Here i have created RichCommandLink in Bean, in this i want to add the <f:attribute>
how to add this in my current component.
can you give some example..
please help..

How to make a column as command link

hi,
how to make a column as command link.i want to make a table column as a command link so that a popup will come.please let me know.
thanks in advance

JDeveloper 10.1.3 does not have a popup but a dialog framework that opens a dialog in a separate browse window. As Chris pointed out, the developer guide contains a section about how to launch the dialog. To programmatically launch the dialog from a command link use its action listener property
    public void commandButton_action2(ActionEvent event) {
// make the clicked row the current
//Get access to the value binding
   ValueBinding vb = FacesContext.getCurrentInstance().getApplication().createValueBinding("#{bindings.DepartmentsView1Iterator}");
   DCIteratorBinding dciter = (DCIteratorBinding) vb.getValue(FacesContext.getCurrentInstance());
//the command link is a child of af:column, which is a child of af:table
CoreTable ct = (CoreTable)actionEvent.getComponent().getParent().getParent();
//access the row data, to obtain the Row object and the formatted key string
JUCtrlValueBindingRef juctrlref = (JUCtrlValueBindingRef) ct.getRowData();
String rowKey = juctrlref.getRow().getKey().toStringFormat(true);
//set the current row in the binding
dciter.setCurrentRowWithKey(rowKey);
// open dialog
        FacesContext fctx = FacesContext.getCurrentInstance();
        AdfFacesContext adfFacesCtx = AdfFacesContext.getCurrentInstance();
        UIViewRoot viewRoot = new UIViewRoot();
        viewRoot.setViewId("/yourDialogPage.jspx");
        HashMap properties = new HashMap();
        properties.put("width",300);
        properties.put("height",200);
        adfFacesCtx.launchDialog(viewRoot,properties,(CoreCommandLink)event.getSource(),true,null);
}If the dialog is based on the same VO then the current row is selected. If not then you may want to pass the value ofthe rowKey in a HashMap as the last argument to open dialog

Displaying a mixture of text and links in a single node of af:tree

Hi,
I want to display few links embedded in text as a node in <af:tree>.
For example, I want a single node in a tree to show three links with text - "Different type of email services are gmail, yahoomail,hotmail".
(gmail,yahoomail and hotmail are links)
Is there a good way of displaying this? I tried following options
1) I have a property named "linkText" in a bean instance mybean of MyBean.java. "linkText" contains required text and "a href" tags to display links. I used the following code in jsp page
<af:tree>
<f:facet name="nodeStamp">
<f:verbatim>
#{mybean.linkText>
</f:verbatim>
</f:facet>
</af:tree>
<f:verbatim> displays the EL expression as it is. I am not able to access the value.
2) I also tried to use <af:outputFormatted>. Though it supports "a href" tag, it does not support "target" attribute of the same tag.
Is there any other way of doing this?

A: Displaying a mixture of text and links in a single node of <af:tree>

On a related note ...is it possible to call a commandLink to call an existing java bean/function within an outputText?
For example:
Say I had an outputText that dumped a /etc/hosts file and I wanted to put in a command link to ping each host and pass the particular IP address to it. What would be the best method for doing that?
135.122.29.122 host1.me.com {color:#ff0000}_PingMeLink_
{color}135.122.29.117 host2.sd.me.com _{color:#ff0000}PingMeLink{color}_
So can I embed this in an outputText somehow or is there a better way to do this?
<af:commandLink text="PingMeLink"
action="#{NetworkController.PingAHost}"/>
Thanks for your help!

How to use a link in a tree

System: Oracle 8i on HP-UX, Forms 6i on WINNT.
Imagine a Forms app which contains a tree with all
accessible forms applications.
Each item is related to a command line which is
stored in the database and executed when the item
is doubleclicked.
This fires the trigger when-tree-node-activated
which executes 'cmd/c ||pathname||filename'.
and the file which will be executed is usually a
.bat file which then starts another form
with path\ifrun60.exe module=*path*\form.fmx usesdi=yes.
This works really fine and all users are happy
and me too, because any other new application
can easily be added. Now my question:
How can I use a similar construction with Oracle 9i
and 9iDS ? My customer is considering this switch.
How can I use a link instead of this batch ?
Every advice is greatly appreciated.
Best regards,
Udo

Depends where the code needs to be run - if it needs to be run on the App Server machine then keep the code you have today.
If it needs to be run on the Client (Browser) machine then look at the HOST bean sample on OTN (otn.oracle.com/products/forms)

Command link used as tree node
