TreeByNestingTableColumn UI element

Hi,
in the "Web Dynpro UI Element Reference Guide" there is
description of the TreeByNestingTableColumn UI element.
However, in the NWDS I could not find it in any group
of UI elements. Is the NWDS support for this UI element
missing?
regards
Sasa

This is a special type of table (master) column. It can only be aggregated to a table, not used standalone.
You find it in NWDS in the <b>outline view</b> of the view designer. Open the context menu on a table elment and select "Insert MasterColumn".

Seeking Help:Using TreeByNestingTableColumn UI element

Dear All,
I have a set of search results in a resultset.Each result belongs to a category.
For example,(refer below) lets say i have 4 results in the resultset and 3 of them belong to category 11
and one belongs to category12.
Now what i want is to display the results in a tree structure such as below using a TreeByNestingTableColumn UI element :
Category
Category1
     Category11
     result1
     result2
     result3
     Category12
     result4
Category 2
Note:category 2 should be visible only if it has some records under it.
So,I have the records in the ResultSet and i have to arrange them as above.The records in the resultset will have only categories at the level of Category11 or Category12 and not the parents.The parents also have to be taken from a master table.
I'll appreciate any thoughts on this.

Hi Karambir,
you have to create a context node with value attributes for data which you want so show and with a recursion node. Additionally you must define attribute value for control (properties you bind to UIElement properties visible, isLeaf, expanded), in run time you must fill it with data from result set and set proper values for control properties (e.g. false for visible in category which have no result to show). In MasterColumn (treeBy NestingTableColumn element) you must bund properties to context and that should work:)
I afraid my description is complicated a little but I hope that can help you solve your problem.

Bogdan

Sorting TreeByNestingTable column

Hi all,
I have implemented my table as discussed here:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/tutorial on creating a tree structure in a table - 27.htm
Now I'm trying to sort my table columns as described here:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/tutorial on creating tables in web dynpro - 11_0_.htm
Unfortunately I cannot get it to work. The icons for ascending and descending appear, however, it does not sort my table columns.
Is it all possible to sort using these TreeByNestingTableColumn UI element components?
And if yes, how can it be done?
Can you please suggest?
Regards,
Harm de Laat

This looks very promissing however, when I paste the TableSorter class into my project, it cannot resolve imports, and has some other import problems:
import com.sap.tc.webdynpro.clientserver.uielib.standard.api.IWDAbstractTableColumn;
import com.sap.tc.webdynpro.clientserver.uielib.standard.api.IWDTableColumnGroup;
import com.sap.tc.webdynpro.clientserver.uielib.standard.api.WDTableColumnSortDirection;
All seem to cause compilation problems.
I'm using NWDS 2.0.15. Anything I should know here?
Please suggest?
Regards,
Harm

WDA: TreeByNestingTableColumn and ALV in webdynpro for ABAP

Hi,
1) I am trying to implement a tree with nested structure and multiple columns. I am using RecursionNode in the context and UI element TreeByNestingTableColumn. I am not able to figure out how to make a distinction between the key and parent key. In TreeByKeyTableColumn, we use key and parent key to differentiate. Is there any link which explains how to implement TreeByNestingTableColumn in Webdynpro for ABAP? (I got a link for webdynpro for java though).
2) Can ALV be used to implement a tree structure instead of using Table with TreeByNestingTableColumn or TreeByKeyTableColumn? Then I would be readily able to use ALV features like sort etc. If it can be used is there any link which explains how to do it in Webdynpro for ABAP?

Hi Srinivasa,
I can answer the first point. If you use a recursive node and TreeByNestingTableColumn, there is no need to have a rowKey and parentRowKey, since the recursion with the context already defines the hierarchy. As far as I know someone posted a blog that explains how to use the TreeByNestingTableColumn in Web Dynpro Java. I don't have the link available, but this blog would be good place to start. The implementation in WDA and WDJ is pretty much the same here.
Kind regards,
Thomas

Drag and Drop from Table with Treebynestingtablecolumn

Hi,
I am using table UI element in Webdynpro ABAP.
And I am showing data in tree format using element TreeByNestingTableColumnn.
Now I tried to implement the Drag functionality for a nested table line and I face two problems:
1. The requirement is to drag an item out of the table without selecting the reow before! I tried it (by implementing a dragable image etc.) but it seems that it is necessary to select the row first before being able to drag. The problem is that I don't use the property row selectable, so I can't select and therefore I cant drag, right?
Is it possible to drag an item out of the table but not selecting it before?
2. In the meanwhile I decided to use the property "row selectable". Now I am able to drag.
BUT, if I drag a nested item (a child item) and drop it, then - instead of the expected data-reference of the selected item - the data reference of the fathers node will be provided within wdevent. Does anyone know why? and is my requiremnt solvable?
Thanks and regards
Oliver

Hi Saravanan,
thanks a lot for your answer. I was happy to hear that someone else also has the same curious problems than me
In the meanwhile I was able to solve my requirement and I describe the solution here:
- Important is how the table is defined:
--> Set rowSelectable to 'true'
--> Set selectionMode to 'none'
- Insert a column. Insert as CellEditor an "Image". Mark the image as "isDragHandle". Now insert a DragSourceInfo.
Take care on correct data binding.
For any reason it works now With Treebynestingtablecolumn and without selecting a row, but by dragging the image.
Best regards
Oliver

How to use TreeByNestingTableColumn in CE SP3 ??

(WD ABAP) TreeByNestingTableColumn in ALV?

To anybody who can answer this:
Is it possible to have a TreeByNestingTableColumn in the ALV? And if it is, can someone provide code as to how this is possible?
Regards,
Christopher Cedro

Hi Christopher,
Unfortunately, this is not possible. I am afraid you need to switch to using the table ui element directly or to refrain from using a hierarchical column.
Best regards,

WD 4 ABAP - expanded nodeelement in TreeByNestingTableColumn

Hi,
I am using the TreeByNestingTableColumn to show a hierarchy table in WD 4 ABAP. When clickin on the norgie triangle in front of the hierarchy parent element, I need to access this node element in the event handler coding. How do I access this element, it is not the get_lead_selection () element?
Thank you for you help. Cheers, Robert

Hi Robert,
reading the leadselection is not sufficient, because it would only read one level. To get it in your nested table, use method CL_WD_DYNAMIC_TOOL=>GET_TABLE_TREE_LEAD_SELECTION.
Ciao, Regina

TreeByNestingTableColumn - how to set lead selection?

Hallo Guys!
I am using TreeByNestingTableColumn in my project. I am searching for a way to select a certain context element inside of the tree shown in such a table. I actually know that setLeadSelection doesnt work properly in such a case.
Ive already read this very helpful blog /people/valery.silaev/blog/2005/06/20/master-of-columns-part-ii searching for a solution, but its seemed not to be there.
Valery had shown how to read the selected context element recursively, but there is nothing about to how to set the needed lead selection for a certain one.
In my scenario, I am loading the whole table (10-15 elements) with only two levels of hierarchy. After the user clicks on a button I have to reload this table but keep the selection of the previously selected element.
The try using getTreeSelection didnt succeed either.
Any ideas?
Many Thanks
Dimitri
Edited by: Dmytro Lubenskyy on Apr 1, 2008 3:44 PM

Hi,
You can use the following methods to set the selection.
IWDNodeElement nodeElement = wdContext.nodeOrders().getElementAt(2);
wdContext.nodeOrders().setTreeSelection(nodeElement);

GetLeadSelection of a branch in a TreeByNestingTableColumns

Hi all,
I'd insert a Tree into a Table by using the TreeByNestingTableColumn.
Moreover I'd added to that Table another Columns with a CheckBox.
My question is:
How can I get the lead selection of the tree's branch when I toggle the corresponding Check Box?
My Table has 3 columns:
-Master Column that contain the Tree
-ID of the Tree element
-Check Box
I hope that the prblem is clear.
Thanks a lot.
Gianluca Barile

Hi Gianluca,
Just navigate down in the context starting from root node of the tree-part following the leadSelection. Another option would be register for the onLeadSelection event of the table and to store the leadSelection at some place that will be accessible from the event handler of the checkbox.
Best regards,
Thomas

TreeByNestingTableColumn and sorting rules for children

Hi,
i have created my first WD Application by using a table with a TreeByNestingTableColumn. My question is how can i influence the order of the children. It seems that the order is hard coded and depends on the sequence of the entries in the table. I added and moved the childs on differnent positions in the table ( by using "bind element ..index x ) . I expected a special field/attribute in the UI element which can be used to influence the sequence of the children.
A second question: Is it possible to combine WD-ALV table with a TreeByNestingTableColumn ? I have the impression that you only can use TreeByKeyTableColumn within WD-ALV to build a hierachy.
Thanks in advance, Juergen

Hi Juergen,
The ALV does not support the hierarchy functionality. As far as I know the only way to get a hierarchy is to build a table, sort and collapse by one column.
Especially the tree by nesting is not supported by the ALV.
Just use the normal table control with the mastercolumn.
Ciao, Regina

LinkToAction inside TreeByNestingTableColumn

Hello Guys!
Does anybody knows how to get a reference to the context element using the onAction method of the LinkToAction UI element inside a TreeByNestingTableColumn?
The onAction is being called but I cannot get the current context element.
In the wdModifyView I did the source mapping for LinkToAction element but a runtime exception is being thrown.
I'm using NW SP12.
Best Regards,
Marcelo

Using Adobe Bridge with Photoshop Elements

I have an iMAC with iLife 08.
I take photos in RAW format with a Nikon camera.
I have been editing photos this way:
After uploading photos to iPhoto, export them as jpg to a new folder on the desktop, external HD or wherever. I open Photoshop Elements, edit the exported photo.
Then I'm stuck with my edits outside of iPhoto, unless I then import them back into iPhoto. It works, but it's cumbersome.
Today I thought I'd try a different route. I opened Photoshop Elements, and tried to use Bridge to browse photos. I can find the iPhoto library easy enough, but if I click on it, it opens iPhoto, and I'm stuck - can't open the photos in Photoshop.
I am hoping that if I do it correctly, I can save my edits directly back into iPhoto.
Any ideas?

Using Photoshop (or Photoshop Elements) as Your Editor of Choice in iPhoto.
1 - select Photoshop as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.
2 - double click on the thumbnail in iPhoto to open it in Photoshop. When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done.
3 - however, if you get the navigation window that indicates that PS wants to save it as a PS formatted file. You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.
This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..
If you want to use both iPhoto's editing mode and PS without having to go back and forth to the Preference pane, once you've selected PS as your editor of choice, reset the Preferences back to "Open in main window". That will let you either edit in iPhoto (double click on the thumbnail) or in PS (Control-click on the thumbnail and seledt "Edit in external editor" in the Contextual menu). This way you get the best of both worlds
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Photoshope Elements when selecting an action, the paint brush tool doesn't work and system keeps freezing, then catching up every 30-45 seconds

I have been having this problem with elements ever since the last OS upgrade, but it wasn't all the time and it wasn't very bad. Now, I have upgraded my macbook again, and I cannot even edit a photo!! I open the photo, choose an action, say "smooth skin", then choose the paint brush, I start to "paint" over their face and it won't paint a line, I have to keep clicking it, click - it paints, move brush, click again - it paints. Plus, every time I choose a tool or an action, it freezes for about 10 seconds, then catches up to what I am doing, 30 seconds later, it freezes again. HELP!! I have 8 sessions to finish editing by this weekend!! I just want to cry!!

Try deleting the prefs and the saved application state:
