A dynamic tree question

i have found some example about how to create dynamic trees... and also found and example wich is similiar to my case on how to Building a hierarchical tree from recursive tables(Frank Nimphius' Blogbuster)....
i have a answer.... i want for the same example to hve on the right of the tree a form in wich i can add the eleemtn in the tree.... so i need a form to add element , and three buttons to add , delet, and save elements from the forms, in the moment they are deleted from forms are also deleted from tree....
can anyone pls give me and idea how to do this :):) or there is any similiar example with this case..
thanks in advance !

to be honest, your question has been asked countless times already.
use the 'search forums' box at left. some possible keywords

How to create a dynamic tree report

hi experts,
i have a requirement to create a dynamic tree report in OM module.
this report should show the number of people positions required in a org unit, and also the number of people available in a org unit.
There is something called as qualification catalog to which qualifications are attached, to these qualifications org units are attached, these org units will have some positions attached to it, and each of this position might have a person attached to it.
The user will enter the qualification catalog number in the selection screen for which he should be getting the result in a tree format which flows from qualification catalog to qualifications, from qualifications to org units, from orgunits to the total no of positions present in this orgunit and the no of positions occupied in the orgunit.
This is a challenging job as far as i am concerned.
Please suggest me a way to approach this,i promise to reward the answers.
thanks in advance,
santosh.

Dynamic Tree Creation using JSP, Struts framework

I urgently require tips/information/code snippet for creating a Dynamic Tree structure.
Tree is the hierarchical folder structure that we see in windows operating system.
Dynamic tree in the sense that all nodes shall be populated from database & a radio button shall be present at each node that can be selected & submitted to form.
Tree should be done using JSP (& if required Javascript).
I am using Struts framework .

u need to know quite a few java technologies to make archieve your dream.
JDBC, dynamic array and JSP.
after reading tutorial regarding to these 3 materials, you should be able to get your job done.

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

Another possible option is to show a dialog with no OK button. If you hold a reference to it, you can discard the dialog when the operation is complete.

Custom.xss and dynamic tree

urgent response would be really reappreciated. !!

Images are in /OA_MEDIA directory. In jedv they are in your home directory under myhtml.

Dynamical Tree handling multiple requests

Hi,
I think I already explained well my need. I currently have an
implementation of a tree control that is dynamic. So, when I click
to open a node, it sends a request to server to ask for its
children.
Attached you have my tree code.
And here is a sample feedback I have from server in XML:
<response>
<status>OK</status>
<message/>
<data>
<item id="3" type="folder" label="Item 1.1"
isBranch="true"/>
<item id="4" type="folder" label="Item 1.2"
isBranch="false"/>
</data>
</response>
The problem is that if I the user clicks too fast to open two
branches, only the last request is added. THe other request is
lost, but its node keeps the down arrow. If I try to close it then,
it crashes the app.
My question is how do I make this code able to work with
simultaneous requests? I already tried via AsyncToken without
success. The main problem using tokens is how to pick the selected
item then. =\
Thanks in advance,
Best regards,
Guilherme Blanco

So can u kindly advice me where should I use Servlets here in my application in order to overcome the problem.Dude, you need to study struts as well. There is an underlying servlet handling all the requests, and based on action name it decides which action class it needs to call. All this is done behind the scenes what you as a developer do is write your logic in the Action class (or may be call some services from it). So it would be easier for us, if you can share the code where you have written the logic as well your Action class code.

To Create a Dynamic Tree

Grant,
How to generate a Tree in Oracle 11g Dynamically.
Thanks & Regards,
Srikanth Reddy

What do you mean with 11g of Oracle. There is no 11g of Oracle Forms (which is the forum you posted this question in). Do you mean Oracle Forms 9 or 10?
If so have a search in this forum and in the help files. You will find examples and hints and tips on how to do it.
A general advice about using a forum like this is to show at least a little effort before you post a question. Very few people will take the time to show you from scratch how to do something that is described in the general documentation if you have not even read it and tried yourself first.

If anyone runs into the same issue in future: this JSP implementation evaluates anything in <%=...%> type expressions, and calls toString() on the result. If the result is a primitive type, it can't call toString() - obviously. You also obviously can't call toString() manually, as the second questioner was trying to do.
In my experience, JSPs (or the JSP implementation used in HTMLB development - which, by the way, is not a complete or compliant implementation, by SAP's own admission) also tend to break when you try to perform evaluations in within <%=...%> expressions. For instance:
int i = 1;
<%="myTextLabel" + i%>
generally doesn't work, but:
int i = 1;
String id = "myTextLabel" + i;
<%=id%>
generally does, even though "myTextLabel" +++ i, when evaluated, is a string.

Windows 2008 R2, converting to dynamic disk questions

Hello,
   I have a Windows 2008 R2 server and I want to convert the drive into a dynamic disk for mirroring. The disk currently is divided into two partitions. The C: partition which is System,Boot, Page File, etc. and the D: partition which
is data. The questions I have are:
    Can a disk with multiple partitions be created without data loss or anything?
    I know you have to reboot, but how long does it usually take to do the reboot/conversion before the server is back up?
    I want to mirror the drive to a 2nd identical disk in the server, and am planning to use Computer Management. Do I have to partition the second drive first, or will the process do it automatically?
    The server is a dedicated server that is provided by a hosting company, so I would be doing it through Remote Desktop. Can it be done that way?
Thanks.

Hi,
You can convert the drive into a dynamic disk within both local logon session and remote desktop session. The system requires reboot twice to make the conversion take into effect. You do not have to partition the second drive.
For more detailed information, please refer to the articles below:

Dynamic Tree and TreeNode Issue

I am using JSC2 (060120) on Win2K pro, exporting the WAR and running in JBoss 4.0.3 running under JDK 1.5.0_04.
I am trying to dynamically build a tree as the user clicks on nodes and am not having success following the example at http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/sitemaptree.html
When I attempt to add the child nodes directly to nodes via clickedNode.getChildren().add(myNewNode); I get an error as follows:
10:17:29,260 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
javax.faces.el.ReferenceSyntaxException: AP-1030Child.id
at com.sun.faces.application.ApplicationImpl.checkSyntax(ApplicationImpl.java:749)
at com.sun.faces.application.ApplicationImpl.createValueBinding(ApplicationImpl.java:291)
The ID shown AP-1030Child.id does not exist, my to be parent node is named AP-1030 and my to be child is named AP-1030-Bottom.
The only way I can get the Tree to build properly is to add the to be child (AP-1030-Bottom) to the Tree itself and then assign it's parent as the node (AP-1030). But, the problem I run into then is the next time the parent node (AP-1030) is clicked parent.getChildCount() or parent.getChildren().size() both evaluate to zero and I attempt to build the children for the node at which point the code blows up due to duplicate naming.
Has anyone else experienced this? Am I doing something wrong?
Here is the code I use to build my tree initially on the SessionBean...
for(int i = 0; i < count; i++)
TreeNode newNode = new TreeNode();
newNode.setId("AP-" + pages.pageId);
newNode.setText(pages[i].page);
newNode.setImageURL("/resources/tree_document.gif");
MethodBinding nodeMethodBinding = this.getApplication().createMethodBinding("#{MainPage.treeNode_action}", null);
newNode.setAction(nodeMethodBinding);
this.applicationPagesTree.getChildren().add(newNode);
Here is the code I am using to add the child nodes to the clicked node...
     for(int l = 0; l < locationsCount; l++) {
          TreeNode locationNode = new TreeNode();
String sectionText = "";
          (populate sectionText with Top|Left|Center|Right|Bottom based on data)
          locationNode.setText(sectionText);
          // making unique name for this object in the tree: parentname + section
locationNode.setId(searchID + "-" + sectionText);
locationNode.setImageURL("/resources/tree_document.gif");
          // bind to method for the page sections click
MethodBinding nodeMethodBinding = this.getApplication().createMethodBinding("#{MainPage.locationNode_action}", null);           locationNode.setAction(nodeMethodBinding);
          // adding to the base tree object after the parent (why can I just not add to the node?)
          this.treeList.getChildren().add(insertIndex + l, locationNode);
          // this nudges the node over one, otherwise it is peer to the parent (again, why not just add to the parent?)
locationNode.setParent(node);
Why is it I can get the String ID from the tree and not the object? Wouldn't it make sense to give me the TreeNode instead of it's ID when calling getCookieSelectedTreeNode()? This would seem a more proper object orientated approach.
Any help appreciated, thanks.

Thanks,
I have tried pretty much that exact same code and it does not work for some reason. That code is the same as the example I showed that I followed originally.
The only way I can get it to work is as I showed. When I do the node creation and then add to the node in the tree it blows up while rendering with the message from the original post.

How to create dynamic tree component

I am using netbeans 5.5 and visual web pack to develop my jsf application.
I want to add a tree component that will be tied to a table with following columns:
id,parent_id,name
Actually the table stores data in tree structure with parent_id storing the parent of the row.
So a row with parent_id = 0 will be the root nodes of the tree.
When ever any root node is selected i want to fetch its children from the database and populate then as children of that parent node.
The tree can go to any depth so i want to make my tree component dynamic enough to handle this requirement.
How can i accomplish this.
I just want to add listerner for the plus sign of every node so that when the plus sign of that node is clicked i just want to get the id of the corresponding node.

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.
