Display recursive tree expanded upto element level

Hi all,
I have created a Recursive tree. I want to show expanded tree upto element level. I saw EXPAND_INTO_ELEMENT mehod of IF_WD_TABLE_METHOD_HNDL and SET_ON_EXPAND_ALL from class cl_wd_tree. Is it useful for me.
Please suggest how it works for me.
Thanks
Sanket

Any suggestions.

Selection of elements in a recursive tree structure

Hello,
I have a recursive tree structure, and I am dynamically creating the child nodes as the parent nodes get expanded. The structure at runtime after expansion of the nodes would look something like this:
Node 1
---Node 1.1
Leaf 1.1.1
Leaf 1.1.2
Leaf 1.1.3
---Node 1.2
Leaf 1.2.1
Leaf 1.2.2
Node 2
---Node 2.1
Leaf 2.1.1
---Node 2.2
Leaf 2.2.1
Leaf 2.2.2
When I select an item, say Leaf 1.1.1, that item gets highlighted. Now, when I select another node, say Node 2.1, that item gets highlighted as well. The issue now is that both Leaf 1.1.1 and Node 2.1 are highlighted, although I want only the latest selection to be highlighted.
I have the following settings on my context node of the tree:
Initialization Lead Selection = False
Singleton = False
Selection = 0..1
How can I get only the latest selection to be highlighted on the tree?

Hi Venkatramanan,
You are right - the lead selection works perfectly, and it is just an issue with the appearance. But even so, I would like to know if there is some way to control the visual highlighting of the nodes. The main cause of concern is that for a user, if he selects leaf 1 first, and then leaf 2 (from another node) next, both are highlighted, and there is no way to know which one is really selected.
I did look at the component WDR_TEST_EVENTS. The dyn-load recursive tree does not appear to have this problem, but I could not find any special handling in the code.
One more thing: I have the ignoreAction attribute set to true for all the parent nodes. The leaves have this attribute set to false, so they can be selected. But this does not seem to help with the highlighting issue.
Thanks,
Kamal

Regarding ALV ( To be displayed in Tree Format)

Hi all,
I am working on a ALV report which is to be displayed in Tree Structure . I found some demo programs within SAP .. but do we have an Alternative .. all those Demos use OOPS concept .. Can this Report be done without using OOPS in ALV.
Please Suggest.
Thanks & Regards

Displaying ALV hierarchy at a certain level

Hi all,
I have an ALV report that shows a hierarchy. This ALV hierarchy is created using std class CL_GUI_ALV_TREE.
The number of hierarchy levels is dynamic and only determined during run time. However I would like to be able to either display all nodes expanded or only the last node unexpanded. In other words I would like to control which hierarhcy level is expanded when the report is first displayed.
Can anyone suggest a way to do this please?
Thanks

If you want to display the sum for a given hierarchy level, you should use CUBESET function.
e.g.
=IF(B2="all",CUBESET("mycube","[Location].[Location Hierarchy].[Department].&[DEPT 07]","all"),Cubemember("MyCube","[Location].[Location Hierarchy].[Department].&[DEPT 07].&["&B1&"]"))
Hope it helps.

How to Use MRS Functionality at Activity Elements Level?

When we use Multi Resource Scheduling for resources in PS, we specify "Resource planner process" as process variant at the network header and the Resource planner node.
In the other hand, at the network operation level we are able to choose the same Process variant and the system displays the planner node to start planning; however we cannot do that when using activity elements because the icon to search the Resource planner is gray out.
How can I use MRS functionality at activity elements level?
I will appreciate your help.
Ragards,
Rafael

Hi Rafael...
A question were able to integrate elements activity to MRS?

How to only display specific members from dissimilar hierarchy levels?

Hi,
I have a Business Partner that routinely wants to build a report that displays members from dissimilar hierarchy levels. For example, she wants to display member "210_UNASSIGNED EXP/ACC" from level 8 and member "E090_ADVISOR SERVICES" from level 1. When she filters on just those two members, the reports displays as such:
She then must manually expand the "E020_CORPORATE AND EXECUTIVE" member 7 times to see "210_UNASSIGNED EXP/ACC":
Is there anyway to make her life easier and have the report display only the "210_UNASSIGNED EXP/ACC" member and the "E090_ADVISOR SERVICES" member, even though they are from different levels?
Thanks,

BI4.0 SP8.3
SQL Server 2012

Hello Michael
Displaying information from mixed hierarchy levels without the context of the parent members is a reporting workflow best suited to WebI and CR. The AOLAP content can be exported as an Analysis View and then this becomes a data source for WebI and CR.
Our previous product Voyager used to allow member selection from mixed levels without the context of parent members but it caused a lot of confusion and misinterpretation of the data, which is why we deliberately do not have it in AOLAP.
Worth noting that BI4.1 was a big release for AOLAP with many enhancements. One is "Expand to Level". So instead of having to click 7 times to expand the hierarchy, it now just requires one mouse right-click to do the same thing.
Regards
Ian

Display Recursive Columns in JTREE

I'm having a problem displaying a recursive relationship like
EmpNo & MgrNo in a Jtree to show a management hirerarchy.
I'm using JDeveloper2.0 and trying to load the model with
the data from the two columns....
Is there an example in the documentation that I could follow???
Any help would be greatly appreciated!

null

okay, I was able to access the file system and display the tree, but i still need some help.
What I did was to create a split panes and on the left side i display the file system , and when the user click on the files it should open the selected file in the right side. At this point i can display the file system on the left side , but i can not display the files. The following is the part of the code which i am working on it.
public void valueChanged(TreeSelectionEvent e) {
DefaultMutableTreeNode node = (DefaultMutableTreeNode) tree.getLastSelectedPathComponent();
if (node == null) return;
Object nodeInfo = node.getUserObject();
if (node.isLeaf()) {
i don't know what to put in side of if loop to open the selected file.
I appreciate any help or suggestions

Menu option under recursive tree item/folder & checkbox in tree

Hi,
I want to present a checkbox next to an item or folder in a recursive tree.
I didn't see any option to do it so I tried to add a menu and a menu option type checkbox under the node item and note type.
The issue it does nothing.
Any ideas?
THanks,
Itay

Hi Akshay,
Everything mentioned here step by step:
0. You cannot use check-boxes inside tree, so you have to emulate them with images (or use Table with Tree-like master column -- not discussed in this message)
1. Create boolean attribute isChecked in node
2. Create calculated read-only string attribute cbIcon, write following in generated getter function:
return element.getIsChecked() ?
"~sapicons/b_okay.gif" : "~sapicons/b_canc.gif";
or whatever images you are using.
3. Create & bind action onAction for TreeNode / TreeItem.
-- apply parameters mapping in wdDoModifyView:
if ( firstTime )
final IWDTreeNodeType treeNode = (IWDTreeNodeType)
view.getElement("<your-tree-node-element-id>");
treeNode.mappingOfOnAction()
.addSourceMapping("path", "selectedElement");
Your action must define parameter with type of your node element and name selectedElement
-- write the following code for handler:
selectedElement.setIsSelected( !selectedElement.getIsSelected() );
4. Bind cbIcon attribute as TreeNode / TreeItem image source, bind rest of attributes.
--Done.

Best way to Display a tree in Adobe Forms i.e. Classification

As I am new to Adobe interactive and do not have the experience that many of you have, I am posting a general question in that what is the best way to display a tree like structure of data in Adobe Forms so that a user can select a 'leaf' node easily.
I have looked at and coded drop downs that drive the data in the next drop down and it seems to work but it is not pretty and is a lot of work to handle the requirements for different levels of data. we have suggested that they select the Classification in a Webdynpro pop-up before they go into the form meaning that the classification will only work when they are on line. I looked briefly at using imbeded tables but they would be too big(should I look at them further?).... There could be upwards to 3000 rows in the classification table.
Example of data
Level 1
=== level 11
=== level 12
Level 2
=== Level 21
Level 3
=== Level 31
====== Level 311
====== Level 312
Thanks in advance for any ideas and learnings you may have.
Glenn

After talking to a number of people, I have determined the best way is to use dynamic dropdown lists to show the hierarchy.

Accordion creationPolicy="all" effect on tree expand

facing very strange problem
i have placed 2-3 tree component inside Accordion container.
On each tree's creationComplete i called function to expand first level.
when I set creationPolicy of Accordion to "all", tree expand is not working.
and if I removed creationPolicy from Accordion, all trees are expand to first level at creationComplete but only tree will not expanded.
and idea why this happen?

Your trees' creationComplete routines are being called at an earlier time than they were before. So maybe something isn't set up yet that they depend on.

Recursive tree issue

Hello!
I have made a view object with self referencing view link, dropped the data control onto page, added a rule, chosen attributes.
It works fine, but the tree initially displays all the table rows, since the tree uses a single view object and query is not limiting the data because if i limit it for selecting only root records, the children won't be seen, of course. How to construct a recursive tree, so that it would initially have only root records on top?
Thank you!

This is in 11.1.1.4 btw.
Here's the stack trace if it helps:

We have a copy of the adf 11.1.1.4 source and I checked FlattenedTreeCollectionModel.setRowIndex(FlattenedTreeCollectionModel.java:171) but it doesn't reveal anything. I see the part that rethrows the IllegalStateException, e.g.:
try
//more code here
catch (IllegalStateException e)
IllegalStateException exp =
new IllegalStateException(LoggerUtils.getMessage(
LOG, LoggerBundle.EXCCHANGE_INDEX, new Object[]{_index,index,_rowCount}));
exp.initCause(e);
throw exp;
But I can't find the part that actually throws the IllegalStateException. I'm looking for an explanation as to why this is happening. I understand the solutions above worked for some people but there never was an explanation about what the error is about (e.g. why did the exception happen). The error message is far too cryptic and does not really establish what could be wrong which is just annoying as hell.

Implementing tree control in third level navigation

Hello
1. Is it possible to Implement a tree control inside third level navigation ?
2. How can I make selecting one of the nodes change the display in another iview on the same page ?
(How do they pass data to one another)
3. Is it possible to select several nodes at once ?
P.S
Is there a how to guid out there ?
Thanks
Ziv.

Hi,
I undestand you want to hide/show tree nodes on demand.
in the standard DTN (detailed navigation) it isn't possible.
There are two options -
1. As suggested you can modify the DTN provided by SAP - all the code is under com.sap.portal.navigation.detailedtree.par and the iView name is also com.sap.portal.detailedNavigationTree
2. create this tree from scratch, and put it on the left side instead of the DTN or as a dynamic navigation iView.
For creating navigation iViews by yourself, you can start from here:

Af:tree expand/collapse customization

hi all,
i have problem with af:tree expand and collapse.
I want to expand only one node in each level.
i mean let say i have 3 node in same level.
i expand first one then i expand second node again. at that time, first one should be collapsed automatically.
So, user can expand only one node in each level at one time.
is it possible?
With Regards,
WP

hi Sireesha,
it is really helpful. but it is still something wrong for child node.
only root node is working as i want.
but when i click on child node, it go back to default and every node is collapse.
if i found the following logic is not working for child node.
discloseRowKeySet.add(firstKey);
eg. let say fristkey is (2,0) then it should open 2 and then second level 0. but it can't open any node.
do u have any idea?
With Regards,
WP

CLOSED- Recursive Tree with Recursive Table and seperate Relationship table

Hi All,
I am trying to achieve a adf recursive tree with recursive table but relationships are stored in separate table like
Table A:
id name
1 Val1
2 Val2
3 Val3
4 Val4
5 Val5
Table B:
fromid rel_type toid
1 Parent-of 2
2 Parent-of 3
3 Parent-of 4
1 Parent-of 5
I did lots of reading from forum and various posts but couldn't make it work.
Any suggestion what would be best approach and/or sample code for this ?
Thanks

I think that you can get this done by defining a VO that fetches all the top level nodes and have a view link to a VO that has all the details with a self recursive viewlink
Query for the top level
Select A.id, A.name
from A
Where A.id not in (select disctinct toid from B)
Query for the detail level
Select A.id, A.name, B.from, B.to
from A,b
where a.id = b.toid;
ViewLink is going to be:
detail.from=master.id
and another viewlink for the recursive relationship
detail.from=detail.to

Help with displaying a tree...

Hello,
I created a window program that displays some data in a tree structure. I have two versions of the program. One that works and one that doesn't. The one that does, builds the tree in the constructor method of my window class, creates a scrollPane for it, and adds the scrollPane to the window. Again, this version displays the tree fine.
The second version, what I want to accomplish is load the tree when a button is pressed. When the button is pressed, I execute exactly the same steps that I do in the constructor but now these steps are in the actionPerformed method associated to the button. The thing is that the program does not display the tree. I have tried the repaint methods at the contentPane level, at the tree level, reloading the treeModel, but cannot get the tree to show. I would very appreciate any ideas on this...
Thanks
Antonio

Hey...
Thanks for the tip...that did the trick. What does the validate() method do exactly? The documentation doesn't say much....Thanks again...
