How to expand a tree at a specific node/item?

Hi,
we have a tree and the nodes/items were binded to context with this code
lo_nd_nvccmp = wd_context->get_child_node( name = wd_this->wdctx_nvccmp ).
lo_nd_tree = lo_nd_nvccmp->get_child_node( name = wd_this->wdctx_tree ).
lo_el_tree = lo_nd_tree->bind_structure( new_item = ls_tree set_initial_elements = abap_false ).
We want that the tree is expanded at a specific node/item?
The structure has the field is_expanded of type WDY_BOOLEAN. I think that if the field of the right structure is 'X' then the tree should expanded. How can we find the right structure in the context and change this field to 'X'?
Code is appreciated.
Thanks, regards
Susanne

Oh, apparently if you try that call right after you create
the Tree, it will throw a null reference exception. That might
count as a bug in the flex api...
If you create a Tree, and give it's dataProvider some xml
data, and then add it to the stage (addChild), and then you call
expandItem or expandChildrenOf() right after, you will get a null
object exception. You have to wait... for something. I don't know
what.
I even tried calling _tree.invalidateList() before the
expandItem, but it will still throw the error...
I wonder what the Tree needs to wait for? Is this a bug for
Adobe to fix?

Hi,
Is there a "elegant" way to make blink a treeview node?
I am thinking to use a timer with the collection of nodes that I want to make the blink effect, and update the icon ...

Hi,
You can develop your custom control for this purpose. The logic you mentioned was correct. Here is a sample control that I developed by the logic you mentioned.
public class BlinkingTreeView : TreeView
private Timer t = new Timer();
private List<TreeNode> blinkingNodes = new List<TreeNode>();
public BlinkingTreeView()
t.Interval = 1000;
t.Tick += new EventHandler(t_Tick);
bool isNodeBlinked = false;
void t_Tick(object sender, EventArgs e)
foreach (TreeNode tn in blinkingNodes)
if (isNodeBlinked)
//update Icon
tn.Text = tn.Text.Substring(0, tn.Text.Length - 1);//to test
isNodeBlinked = false;
else
//update Icon
tn.Text = tn.Text + "*";//to test
isNodeBlinked = true;
public void AddBlinkNode(TreeNode n)
blinkingNodes.Add(n);
public void RemoveBlinkNode(TreeNode n)
blinkingNodes.Remove(n);
public void ClearBlinkNodes()
blinkingNodes.Clear();
public List<TreeNode> BlinkingNodes
get { return blinkingNodes; }
public int BlinkInterval
get { return t.Interval; }
set { t.Interval = value; }
public void StartBlinking()
isNodeBlinked = false;
t.Enabled = true;
public void StopBlinking()
t.Enabled = false;
just show me how to use BlinkingTreeView class. i will have tree view which will have few node and few nodes may have few child nodes. now how to achieve by this class BlinkingTreeView and show me how to blink few specific node not all. thanks

better to come with code. first populate tree view with some dummy node this way
Root
       Child1
                Child1-sub1
                Child1-sub2
       Child2
                Child2-sub1
                Child2-sub2
now blink Child1-sub2 & Child2-sub1. please come with code. thanks

Ajax memory tree can't expand when searching for a specific node.

Hi,
I've just followed the ajax tree example. Everything is working except when the find node windows pop up and a node is selected. the corresponding report is displayed but the ajax tree doesn't expand accordingly.
Any help would be appreciated.
Thanks
Venus

I too am having this issue with Scott's search ajax tree example listed here..
http://www.oracle.com/technology/pub/articles/spendolini-tree.html
The correct node is highlighted if that level of the tree happens to be expanded, but the tree is not automatically expanding to show the correct node. Which part of the code is meant to "automatically expand" the tree? Is it the
"if tree_rec.id = y.id and tree_rec.id != v('P1_SELECTED_NODE') then..."
section of "find_node" in
http://www.oracle.com/technology/pub/listings/spendolini-tree-l1.html
Any help appreciated.
Thanks, Penny

How to have a tree view for value node..

Hi all,
I need to display a tree view for a value node in web ui just like a model node, for a custom view in a pop up. Please guide me how to do this or let me know the process steps.
Thanks in advance.

Hi All,
while debugging I found that in class CL_BSP_WD_CONTEXT_NODE_TREE , the method GET_T_TABLE the below code is not triigerring for the child node attributes ( to trigger the get method of attribute for value node).
this call method is not triggering at all only for first coulmn its triggering ..
LV_TN ?= ME->NODE_MAPPER->GET_NODE_OBJECT( <LINE>-NODE_KEY ).
    CONCATENATE 'GET_' COMPONENT INTO LV_METHOD.
    TRY.
        CALL METHOD LV_TN->(LV_METHOD)
          EXPORTING
            ATTRIBUTE_PATH = ''
          RECEIVING
            VALUE          = VALUE.
      CATCH CX_ROOT INTO LV_ERROR.
I created the GETTER method inthe class CN01 and CN02. But those methods are not triggered in CALL METHOD LV_TN->(LV_METHOD). Even that class CN02 is having the same methods. Those methods are already Implemented. May I know what was the reason Why those methods are not triggered ( getter method ). With out that Method data will not display in the Tree view. Can anybody tell me the reason why it is not happenning?
.Please find the below .HTM code as well.
<chtmlb:configTree
                      actionsMaxInRow       = "5"
                   id             = "Table1"
                   nodeTable      = "<%= ZTREEVIEW->node_tab %>"
                   table          = "//ZTREEVIEW/Table"
                   noFrame        = "FALSE"
                   personalizable = "TRUE"
                   onCollapseNode = "NODECOLLAPSE"
                   selectionMode = "MULTILINEEDIT"
                   onExpandNode   = "NODEEXPAND"
                   onRowSelection = "select" />
Only one column was triggered another column did not get any value becasue of the above method call fail.. We are not restricted anywhere to display one column value in the output.   Even in Debugging I checked that LV_METHOD is having the method name. CN02 class is also having the same method, But it is not going into the method. It is coming out side. What could be the reason I could not able to understnad.
Please provide me some pointers on the issue....
Thanks in advance..

ADF Tree Traversal from one node to its leafs

Hello,
after a titanic effort I have been able to add a checkbox next to each node of an adf tree table.
This checkbox is based on an "helper" entity attribute (not mapped to a column table on the database).
My next huge problem is to perform an automatic selection of all the checkboxes next to the nodes under the currently selected one.
For example, if the user checks a checkbox in the second level, then all the checkboxes next to the nodes under that, belonging to level three and four must be checked.
If this helps, in my case there are at most four levels.
Up until now I can get all the information from the currently checked node, but I fail to navigate the hierarchy under it for the automatic checking. I think that one problem is to navigate all the rows in the (only) VO the tree is based on. For example, since the tree is not expanded at the beginning, if I iterate on the VO retrieved from the current selected node at the top level, I can't see any rows corresponding to any children. Maybe I just miss something.
I have followed this example from Frank Nimphius, which only gets the current selected nodes, as I said, but no more. Maybe this is a good starting point, but I need to advance somehow.
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/32-tree-table-from-single-vo-169174.pdf
Can anyone help?
Thanks.

Hi,
here is a sample of how to search in trees, which actually shows how to traverse trees from a specific node
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/61search-in-rendered-trees-177577.pdf
Given you have a transient attribute defined, each node (and instance of JUCtrHierNode --> getRow will give you access to the attribute for read/access). Note that because the checkbox is stamped in the context of the tree, upon selecting a parent node, you need to refresh the tree to show the selection state change

How to scroll to a specific node in the webdynpro tree

Hi all,
I'm developing an application where I need to load and expand a tree upon some action in another view.
Loading the children, expanding nodes and setting a new lead selection (with cl_wd_dynamic_tool=>set_tree_lead_selection) all works fine.
But I did not find a way to scroll the tree, so that the node is in the currently visible area of the tree. Is there a way to do this?
Thanks for your answers!
Best regards,
Frank

Tree is a particular structure, you need to realize a recursive function, specially if the tree with is a recursive TreeNode.
this is a quickly answer, i did this in java.
The idea is the same everywhere, this is an ABAP-LIKE solution, understand and translate in a good ABAP source.
FUNCTION FindNode(TypeNode tree_node, TypeNode node_to_find ).
IF ( tree_node.ELEMENT_ID EQ node_to_find.ELEMENT_ID ).
"""""""    do what you wanna do """""
ELSE.
n = tree_node.GET_NUMBERS_OF_CHILDS;
""""""""" RECURSION
FOR i = 0 TO n.
    child_node = tree_node.GET_CHILD(i).
    CALLFUNCTION FindNode(child_node, node_to_find ).
ENDFOR.
ENDIF.
ENDFUNCTION.

How to create a tree in tree?

how to create a tree in tree?

Hello Luo Cheng
Did you mean to have multiple tree control within a tree control?
I am not understanding what business purpose will this serve to have a tree control inside other? You can always have a specific node and when expanded list all the related nodes.
To have a tree control inside another tree control is not possible.

you really don't need to post all that code, few people will read it, or try to compile/run it.
just a tree in a scrollpane in a frame is all you need, then add the method/problem to the basic,
and post that so its only 20 to 30 lines long.
here's your basic tree/scrollpane/frame, with an expandAll()
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Testing
public void buildGUI()
    JTree tree = new JTree();
    expandAll(tree);
    JFrame f = new JFrame();
    f.getContentPane().add(new JScrollPane(tree));
    f.pack();
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
public void expandAll(JTree tree)
    int row = 0;
    while (row < tree.getRowCount())
      tree.expandRow(row);
      row++;
public static void main(String[] args)
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
}so, is your problem with the expandAll(), or with reading the properties file?

Hello,
I'm a new user in Sol Man !
How to create a test plan with specific transactions (or program).
In my Business Blueprint (SOLAR01) I've created in 'transaction tab' the name of my specific transactions and linked it.
In my test plan (STWB_2) those specific doesn't appear to be selected !
Thanks in advance.
Georges HUYNEN

Hi
In solar01 you have defined but you have to assign the test case in solar02 for this test case in the test cases tab.
When you do so expand the business sceanario node in test plan generation of STWB_2 transaction and now that will appear.

How to create dynamic tree based on BAPI

Hi
I am able to create dynamic tree based on flat file structure example given in SDN . But how to create the tree from BAPI directly.Also when I will be clicking on any leaf node of the tree some data related to the node will be passed to another view.
Regards
Ananda

What i'm trying to do is create an organizational structure.
Global>Region>Plant-->Corporation
The output from the RFC is a structure containing every possible combination for orgazational hierarchy. Basically a flat table with record for every possible combinaton of Region-Plant-Corporation. This data needs to be bound to a tree structure so that we can call BW queries based on that level. For example: Give me aged inventory for the SAP corporation within the plant Berlin that is located in the Europe region.
Now that you understand the business reason will the nodes that represent Region and Plant and corporation be non-singleton nodes or recursive? I was thinking a hierarchy of non-singleton nodes.
I can bind these nodes to the Region - Plant - Corporation elements returned from in the flat table structure. I will probably get duplicates as a specific Region will be listed multiple times for every possible combination of the data beneath it. I'm not so concerned about that right now as I want to make sure I understand how in Web Dynpro to bind the data to the tree.
Hopefully this makes some sense. Can you elaborate on how this may be constructed in context of the view?
Would i create a model node for region (0..n), model node for plant (0..n), and a model node for Corporation (0..n)?
Or does this sound totally incorrect?

We have 3 regions over 50 plants and probably around 500 corporations.

How to re-open tree nodes after a refresh to AdvancedDataGrid's GroupingCollection?

Hello,
I have an AdvancedDataGrid, which has as it's dataProvider a
GroupingCollection. The GroupingCollection's source is bound to an
ArrayCollection. Items in the ArrayCollection can be edited.
After a change to the ArrayCollection, I refresh() the
GroupingCollection so it displays properly. Unfortunately, this
collapses the tree of the AdvancedDataGrid, that is, the previously
open nodes are no longer open. I would like to re-open the nodes
after a refresh.
In the code provided, I have attempted to save the nodes
which were open before the refresh, perform the refresh, then
re-expand the nodes with AdvancedDataGrid.expandItem(). But it
didn't work, and I am stumped.
Any ideas on how to expand nodes in the AdvancedDataGrid?
or
Any ideas on how to allow the user to modify a data item,
including fields used as GroupingFields, in an AdvancedDataGrid?

Yes, I try saving the nodes like this:
//save the currently opened items
openArray = new Array();
for each(var obj:Object in advancedDataGrid.openItems)
openArray = openArray.concat(obj);
and then restoring them with the expand function:
//expands the nodes which are passed in as the argument
private var expand:Function = function(array:Array):void
for each(var obj:Object in array)
advancedDataGrid.expandItem(obj, true);
Unfortunately, expandItem just seems to return without doing
anything!

How to highlight a tree node programmatically

Problem
=====
Just like a typical management software, I have a navigation tree presenting a list of objects (let's say toasters) on the left panel. The content panel on the right side presents the details of a toaster, when the user selects the toaster on the navigation tree. On the toaster details panel, I would like to have a hyper link referring to another toaster - associated to the selected toaster. On clicking on the hyperlink, I would like to display the details of the associated toaster and the navigation tree node for the associated toaster being highlighted.
For example, BUI presents the following now:
+ Toasters | Toaster 1 Details [Refresh]
+ <toaster1> |
+ toaster2 | ... toaster3
+ toaster3 |
toaster1 is selected on the navigation tree. The contents panel displays Toaster 1 details, which has a hyper link for toaster3.
When the user click on toster3 on the contents panel, I would like to see the following
+ Toasters | Toaster 3 Details [Refresh]
+ toaster1 |
+ toaster2 | ...
+ <toaster3> |
My Trial
=====
ADF Rich Client 11.1.2.3 is used for my development.
Jspx code for the navigation tree looks like this:
<af:tree id="navTree" ...>
<f:facet name="nodeStamp">
<af:panelGroupLayout id="nodePgl">
<af:switcher facetName="#{stamp.outcome!=null?'actnode':'noactnode'}" ...>
<f:facet name="actnode">
<af:commandLink id="leafLink" text="#{stamp.label}" action="#{stamp.actionOutcome}">
<af:setActionListener from="#{stamp.key}" to="#{treeHandler.selectedMenuItem}"/>
</af:commandLink>
</f:facet>
<f:facet name="noactnode">
<af:outputText id="notLeafText" value="#{stamp.label}"/>
</f:facet>
</af:switcher>
</af:panelGroupLayout>
</f:facet>
</af:tree>
The hyper link on the contents panel looks like this:
<af:iterator var="toaster" value="#{toastData.toasters}">
<af:commandLink text="#{toaster}" action="#{toasterHandler.goToToaster}">
<f:param name="toasterId" value="#{toaster}"/>
<af:setActionListener from="#{toaster}" to="#{treeHandler.selectedToaster}"/>
</af:commandLink>
</af:iterator>
I got some tips from this forum (cannot find thread at the moment) and implemented the treeHandler.selectedToaster method as follows:
// getSelectionState returns selStat, which is instantiated like the following:
// RowKeySet selStat = new RowKeySetTreeImpl();
// TreeModel model = (TreeModel) menuModel.getWrappedData();
// selStat.setCollectionModel(model);
// selStat.setContained(true);
RowKeySet rowKeySet = getSelectionState();
rowKeySet.removeAll();
// synthesize the rowKey for the selected toaster
// if the toaster found in the toaster node list,
// rowKey should look like [0, <rowIdx of toaster>]
ArrayList<Integer> rowKey = new ArrayList<Integer>();
rowKey.add(0);
rowKey.add(new Integer(rowIdx));
TreeModel model = (TreeModel) menuModel.getWrappedData();
model.setRowKey(rowKey);
model.setRowIndex(rowIdx);
rowKeySet.add();
This seems to work most of times except when I refresh the contents details panel using partial page rendering.
I get NullPointerException on the call to rowKeySet.removeAll().
Caused by: java.lang.NullPointerException
at org.apache.myfaces.trinidad.model.RowKeySetTreeImpl._selectAll(RowKeySetTreeImpl.java:459)
at org.apache.myfaces.trinidad.model.RowKeySetTreeImpl.removeAll(RowKeySetTreeImpl.java:146)
In my observation, this NPE happens when rowKeySet.size() returns 1 but rowKeySet.iterator() does not return any entries.
I suspect this is a bug on RowKeySetTreeImpl but not sure.
Help Need
=======
1. What is the reasonably right way to highlight the tree node for my problem?
2. If my trial is one way to do it, how can I get around the NPE? I cannot change ADF Rich Client library at this point.
Any help/suggestion/advise would be appreciated.
Thanks,
Jeongtae

I did this, to programmatically expand a tree node, you can try the same and set the row key to highlight.
private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();
public void rowDisclosureListener(RowDisclosureEvent rowDisclosureEvent)
Iterator added = rowDisclosureEvent.getAddedSet().iterator();
if (added!=null)
while (added.hasNext())
Object rowKey = added.next();
//disclosedTreeRowKeySet.clear();
List path = (List)rowKey;
for( int i=0; i< path.size(); i++ )
List<Object> nodePath = new ArrayList<Object>();
for( int j=0; j<i; j++ )
nodePath.add( path.get( j ) );
disclosedTreeRowKeySet.add( nodePath );
disclosedTreeRowKeySet.add( rowKey );
System.out.println( "disclosed Keys...... " + disclosedTreeRowKeySet );
private void expandSelectedNode(RowKeySet addedObj) {
if (sourceTreeTable != null) {
Iterator added = (Iterator)addedObj.iterator();
if (added!=null)
while (added.hasNext())
Object rowKey = added.next();
List path = (List)rowKey;
for( int i=0; i< path.size(); i++ )
List<Object> nodePath = new ArrayList<Object>();
for( int j=0; j<i; j++ )
nodePath.add( path.get( j ) );
disclosedTreeRowKeySet.add( nodePath );
disclosedTreeRowKeySet.add( rowKey );
sourceTreeTable.setDisclosedRowKeys(disclosedTreeRowKeySet);
}

How to create a tree structure,like I want to create Bill/Payment Tree

How to create a tree structure , like I want to create a Bill/Payment Tree containing a single node for all A/R related activities for a specific bill period, in reverse chronological order. Basically the tree should look like
+ Bill - Date: 03-17-2010 Complete
+++++ CR Note - Date: 05-04-2010 Complete
++++++++++ Pay - Date: 05-04-2010 Frozen
+ Bill - Date: 03-17-2010 Complete
+++++ Pay - Date: 05-04-2010 Frozen
And finally this should be attached as tab on the control central

The FTree package provides functions to populate the tree - look for the topic "Manipulating a hierarchical tree at runtime
" in the online help this point to all the functions and triggers
