Node duplication

Any API for duplicating a node with all the same attributes?
clone() ?

JavaFX classes donot implement Cloneable, so clone() is out.
They donot implement Serializable either so tricks relying on that are not going to work either.
You could look into a framework that can do this copying, like Dozer, but I suspect it might be easier to do it yourself depending on your use case.Thanks. Since the size of the distribution is sensitive, any third party library should be avoided. I am afraid, the best solution then would be duplicate it by my self.

Please help with JTree Node Duplication

Iam building a JTree which should not allow node duplication.
1.)First i construct a ArrayList which stores all the previous nodes.
treeNodeNames=new ArrayList();
2.)i call the method
          readTreeNodeNames((DefaultMutableTreeNode)dtm.getRoot());
3.)The method readTreeNodeNames is
public void readTreeNodeNames(DefaultMutableTreeNode node) {
          if(node.toString().toLowerCase().length()!=0) {
          treeNodeNames.add(node.toString().toLowerCase());
          for(Enumeration en=node.children();en.hasMoreElements();) {
               DefaultMutableTreeNode childNode=(DefaultMutableTreeNode)en.nextElement();
               if(childNode.toString().toLowerCase().length()!=0) {
                    treeNodeNames.add(childNode.toString().toLowerCase());
               if(!childNode.isLeaf()) {
                    readTreeNodeNames(childNode);
4.)i have four menu when right click a node add,modify,add subnode,delete.
node duplication fails in my case.when should i call this method?should i call while doing every above mentioned operations or in TreeModelEvent implementations?
i have mailed this problem already two times.but no one has not replied.Kinldy consider it and give me a solution.Or anyone having code for JTree Node duplication please send me to [email protected]

Hi all,
Any ideas to overcome this problem.?
Thanks,

JTree node duplication

I have a JTree which checks for duplication everytime a child node gets added.I have a combobox in cell Editor from which user can select the child node or he can give his own name also.If the node is already added,it will give a warning dialog.I have set root node as 'Device'.If i add 'Device' again in the tree somewhere,the warning dialog pops up two times.I want the warning dialog to come only one time.For other names it comes only once.I use arraylist to store the names of the nodes already added in tree and compare the new node(to be added)with them.i have given the code here..
public void readTreeNodeNames(DefaultMutableTreeNode node) {
     treeNodeNames.add(node.toString().toLowerCase());
     for(Enumeration en=node.children();en.hasMoreElements();) {
     DefaultMutableTreeNode childNode=(DefaultMutableTreeNode)en.nextElement();
     treeNodeNames.add(childNode.toString().toLowerCase());
     if(!childNode.isLeaf()) {
     readTreeNodeNames(childNode);
public void treeNodesChanged(TreeModelEvent tme){
     selectedNode = (DefaultMutableTreeNode)hierarchyTree.getLastSelectedPathComponent();
     if(treeNodeNames.contains(selectedNode.toString().toLowerCase())) {
     Toolkit.getDefaultToolkit().beep();
     JOptionPane.showMessageDialog(this,BuilderUtils.getString("DDFE.DeviceHierarchyScreen.warningMessage5.text"),"Warning!",JOptionPane.WARNING_MESSAGE);
     setEditable();
public void setEditable(){
     treeNodeNames=new ArrayList();
     readTreeNodeNames((DefaultMutableTreeNode)dtm.getRoot());
     TreePath treePath=(TreePath)hierarchyTree.getSelectionPath();
     hierarchyTree.expandPath(hierarchyTree.getSelectionPath());
     hierarchyTree.setEditable(true);
     hierarchyTree.startEditingAtPath(treePath);
     updateUI();
public void createNode(){
     // code for creating a Node at same level
     selectedNode=(DefaultMutableTreeNode)hierarchyTree.getLastSelectedPathComponent();
     parentNode=(DefaultMutableTreeNode)selectedNode.getParent();
     DefaultMutableTreeNode node=new DefaultMutableTreeNode("");
     rootNode=(DefaultMutableTreeNode)node.getRoot();
     dtm.insertNodeInto(node, parentNode, parentNode.getChildCount());
     TreePath tp = new TreePath(node.getPath());
     hierarchyTree.scrollPathToVisible(tp);
     hierarchyTree.setSelectionPath(tp);
     setEditable();

What you can do is to create a second TreeNode with same userOject as in first.

Problem with trees(Duplication of the parent node in creation of children)

Hi guys i am experiencing a slight problem with the creation of trees.Here is a clear explanation of my program.I created a program that generates edges from a set of datapoints then use each and every edge that is generated to create multiple trees with the edge as the rootnode for each and every tree.Everything up to so far everything went well but the problem comes when i want the program to pick every single tree and traverse through the set of generated edges to create the children of a tree.What it does at the moment for each tree is returning the a duplication of the parent node as the child nodes and that is a problem.Can anyone related with this problem help.Your help will be appreciated.

Your program description makes no sense. What exactly is it supposed to do?
Your errors make no sense. What is it doing wrong?
Your program output makes no sense. Look up pre-order, in-order, and post-order notation for representing trees. Pick one of those that you think would be best. I would go with pre-order. Because what you are doing isn't understandable.
By the way, I think your concept of a tree is flawed. A node in a tree has 3 things. it has a reference to its parent, it has references to any of its children, and it has some key value that represents the node (if each node were represented by numbers, the value would be an integer or something). In the case of the root, its reference to its parent is null. I don't know what you are doing with your tree, but it is highly confusing.

Duplication of nodes in JTrees

Hi,
I have GUI a system in which one of the screens contains a JTree which in turn contains two JTrees. Whilst the two internal JTrees have different names they each contain nodes which have the same names as nodes in the other tree.
My problem is that when the trees are fully expanded and I select one node and call setIcon(Icon) on it both it and the one with the same name in the other tree are updated with the new icon. The server side cannot provide me with any different values to display in the trees and setIcon(Icon) does not seem to be able to distinguish between the two (ie selected and unselected) when it is called.
Any ideas would be gratefully appreciated.
Thanks

Here is the code, sorry the tabs etc did not come out properly:

          Object value, boolean selected, boolean expanded,

          String nodeStr = value.toString().trim();
          if(nodeStr.equals(sysAStr))
               isSYS0 = true;
               isSYS1 = false;
          else if(nodeStr.equals(sysBStr))

               isSYS1 = true;
          // if node is leaf or SYS-SYS interface test
          if (leaf || value.equals(currentLocale.getString("SYSABInterfaceTest")) ||
          value.equals(currentLocale.getString("SYSBAInterfaceTest")))
               // set icon on tests to run
               if (CTGPanel.selectedTestsArrayList.exists(nodeStr, isSYS0))
                    // components on different SYSs may have the same path, ensure that the correct path is set
                    MONTreeComponent component = CTGPanel.selectedTestsArrayList.getComponent(nodeStr, isSYS0);

ABAP OO: Duplication of selected data in created objects?

I am new to ABAP OO and I have a conceptual question/concern that I cannot resolve. Can someone explain what I am missing?
I would think that selecting and storing (in internal tables) a large amount of data from many related database tables and, at the same time, creating and storing objects from this same data would unnecessarily consume a huge amount of memory. To avoid this problem, it seems that the selected data and created objects should not be stored in internal tables simultaneously.
Does this concern make sense? If so, how is this problem best handled?
Does it make sense to delete the corresponding data once the objects are created (to free memory)?
Or does it make sense to keep the data and only temporarily create objects as needed?
Thanks.

Hello Matt
The approach you describe is to select data first and the feed the object instances with them. <b>Why not let the object instances do the data selection themselves?</b>
I will give you an example what I mean.
(1) Lets assume I want to write an application that allows to deal with cost center hierarchies. On the selection screen you can choose one or many cost center hierarchies.
(2) Using the selection criteria I would select all cost center hierarchies but without any details (just the key values).
(3) Next I would loop over the cost center hierarchies and create a cost center hierarchy instance (a class you have to define yourself) for each key value. The CONSTRUCTOR of this class will have an IMPORTING parameter like <i>id_kostl_hier</i>.
(4) In the CONSTRUCTOR method I first check if the cost center hierarchy exists (if not raise an exception-class based exception) and then do the selection of the hierarchy details (e.g. the cost centers).
(5) The instances are collected in an itab of the "frame" application.
Using this approach you will have little duplication of data within your application. Furthermore, if you really have to deal with huge amounts of data then you could read them only on demand (like in tree controls where the sub-nodes usually are read when the parent node is expanded).
Hope I could give you some fresh insights into this exciting topic.

Uwe

Same child value under different parent node and these also some childs

Hi guys,
Can anyone suggest me on the hierarchy creation with duplication of node data as
follow we have
one text node under 3 childs and these have same data value &
these have some child values
here we have problem with same data node as not accept the following childs..
pls help me on this.....

Hierarchy from flat file loading with errors - duplicate node names

Hello experts,
I am loading a product hierarchy from a flat file into a custom hierarchy
object. The issue is that it errors out saying I am loading
duplicates within nodes, however all node IDs within a level are unique.
It seems to be looking at the node name to determine uniqueness and I know
we have some duplication within the text there especially when you factor
in the 32 character limitation for the node name. Does anyone have an idea
as to whether it is possible to have it only consider the node ID instead
of the node name to determine uniqueness?
A colleague suggested using the link ID to fix this problem but I don't know how that field works or how to populate it.
I'm working in a BI 7.0 environment (I don't know if that makes a difference since you still have to use the 3.x objects to extract the hierarchy).
Any help would be appreciated.
Nancy

Hi Nancy,
You may wish to check this OSS Note 1026749 - Hierarchies: Consistency check for duplicate nodes and 912115 (old one)
Symptom -
When you load or activate a hierarchy it terminates with error message RH 109 or RH 211. The hierarchy contains duplicate nodes and this is not allowed. The long texts of messages RH 109 or RH 211 do not describe the reason for the problem sufficiently or they are partially incorrect.
There is uncertainty about in which cases duplicate nodes exist in a hierarchy and in which cases duplicate nodes are allowed.
Hope this helps,
Bye...

Y scale flip in waveform graph when using property node.

I'm having problem with property node. I'm trying to build a stackable scope with Waveform Graph And dynamically change the number of plots. It is working. But The Y scale is flipping. The minimum goes on the upper part and the minimum scale goes down. when I change it appearance it's not very fast. It take about 1 or 2 second on my computer.
The way it is build actually is:
Cluster_1 is containing 8 clusters. And each of the 8 clusters are containing a Waveform Graph. By reference I change the property of each Waveform to make visible or not each of the Waveforms.
First I would like to solve the scale problem and second accelerate the redrawing of my scope.
Maybe there is an other way t
o do what I need.
Thanks.

Wow, you have a neat program! The problem with your y axis flipping is because the last four charts in the cluster were programmed with a flipped axis. I relabeled the charts and it worked correctly.
From what I could tell with your code, you do not need the sequence structures. The one inside of the even actually runs the same code twice. Remove this duplication and you should see improvement. Also clusters are slow, so you should not expect it to blink back with additional coding. Use defer panel updates to get that behavior. I incorporated these changes and attached the program.

Duplication checking

Hello gurus!
Is there anybody who used ADDRESS_SEARCH and ADDRESS_UPDATE badies for duplication checking?
Could you provide me with roadmap (code samples, descriptions) how to use them? My case: Business Partner duplication check by name and telephone number.
I have read next document, but unfortunately this field is still unclear for me.
http://help.sap.com/saphelp_crm50/helpdata/en/a3/eaa43ab9db4814e10000000a11402f/frameset.htm
Thank you in advance!
Kirill

Hello Krill,
1)You are creating a BP,category Organization and saved it.
2)You have activated those BADI'S that you've mentioned(Address_search,Address_Update) what happens is the sytem will carry out a duplicate check based on certain threshold values that you have mentioned in the customizing.(a dialogue box pops up indicating all possible duplicates)
3)You can tell the system that the BP you are trying to create is not a duplicate,
its duplicate, or you can create a cleansing Case.
4)Using BUPA_CLEAR, you can manually search for duplicates, enter the weighing factor, select the process (Note you can manually do the cleansing process of Automatically.
5)Execute the BT and drag and drop the BP you want to cleance.
6)In the transction enter BUPA_CLEAR enter the cleansing case number.
7)Compare the BP for a node comparision.
8)Maintain the number range for Data Cleansing. in CA>SAP BP>Data Cleansing
9)enter the Numebr range object.
10)Define Priorities.
11)Activate Duplicate cleansing.
12)Remember we need to make settings in the BAS(Business Address Service)
which is integrated with the SAP Regional Structure, which has to be populated with data either manually(administration overhead is a constraint, or using a Program), Activate Duplicate check index pools.(SAP Web application server)
13)use Transaction SM30
14) display table /SMBCRM/TSAD10
15) this is where you find all the tables.
Finally If your BADIS(Address_Search and ADDRESS_UPDATE) will work accordingly and they only provide an interface for a third party application to come in to contact and do the actuall work. they are defenitely helpless without an external application. Check with SAP for the list of 3rd Party tool available.
Reward with points.

ORA-24544 When Creating a Standby From RAC One Node

I have a RAC One Node database running on node A and am attempting to create a Data Guard standby on node B using the following RMAN command -
duplicate target database for standby from active database
Error returned is -
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN-04014: startup failed: ORA-24544: Oracle RAC One Node instance is already running.
Can anyone advise ?
Thanks in advance

Hi,
ORA-24544: Oracle RAC One Node instance is already running.
Cause: An instance startup failed because an instance of the Oracle RAC One Node database was already running on one of the cluster nodes.
Action: In Oracle RAC One Node, avoid any attempt to start a second instance by any means while the instance is already running.
I have never used One Node RAC, but it looks like RMAN trying to start an offline instance of current One Node RAC on Node B.

Pradeep

Duplication of messages in Integration Engine Monitoring

I send a file from sender(File System) to receiver (BPM). 1 sender 1 receiver.
There are 2 entries of sender to receiver in Integration Engine Monitoring. These rows are identical.
Quality of Service for File adapter is exactly once.
Could anyone expain this duplication?
Adapter Engine monitoring shows one message of sender

Hi,
pls see the below note for help.
note number: 821267 File FAQ.
. FTP Sender File Processing in Cluster Environment
Q: When running the File Adapter in an environment with more than a single J2EE server instance, the same file is fetched by multiple cluster nodes at once. How do I solve this problem?
A: Initially, please make sure that you do NOT use the processing mode "Test" for your File Sender channel. This mode is intended to be used only for testing purposes and is not guaranteed to work in a cluster environment.
Additionally, please activate the "Advanced Mode" for the respective sender channel or upgrade to SP11 Patch Level 2 or SP12. No further configuration changes are necessary.

Creating DR standby from RAC to single NODE

OS and Database versions Primary:

My scenario:
============
node1:- linuxdb1
node2:- linuxdb2

Point2:- grid and oracle users are on RAC prod database & also same grid and oracle users on SINGLE node DR
Point3:- Took RMAN backup from prod database ( 2 node RAC ) and copied to DR as shown below:
RMAN>backup device type disk format '/u02/stby/%U' database plus archivelog;
RMAN>backup device type disk format '/u02/stby/%U' current controlfile for standby;
scp -rp /u02/stby/* [email protected]:/u02/stby/

Have you tried once again ?
Why cant you go for RMAN duplicate from active database, If you have any concerns then enable trace of RMAN and share the information
rman target / log=/u01/test/rman_log.txt trace=/u01/test/rmantrace.log

Changing Node name and appending sibling in DOM

Dear all,
I have what seems like a trivial problem. In a DOM I want to grab nodes with a certain name, duplicate them and attach the duplicated node with a different name to the original node. The duplication bit is no problem with cloneNode(). But there don't seem to be any method for the other tasks (something like: setNodeName() and appendSibling()). Any ideas?
Cheers!
NetWundi

as for the rename, you will need to just create a new
node, and position it in place of the old one, moving
the old one's children to the new node. As for
appendsibling, there is no such thing, you need to
get the parent, and use insertBefore(Node newChild,
Node refChild)Thank you for the reply! I will try it like this then.
All the best!

BP duplication prevention

Hi,
I need to find, in B2C scenario, a solution where new users cannot create accounts
using duplicate address data.
( When new user tries to create a user with duplicate data the webshop page should show a message, telling certain duplication problems.)
I read that there is an add-on for Service Industries, which is free.
However I do not know how to find and install it.
I also read that it has a transaction code CRM_BUPA_DC for cleansing cases.
If anybody knows how to find the installation files and installation procedure, I will be very grateful.
Regards,

Hi Rahul,
Sure, this can be easily configured.
There is a BADI - ADDRESS_SEARCH which is used to implement duplicate checks on BP name + address. You can either write your own implementation or you can use the SAP provided implementation SIC_ADDRESS_SEARCH.
You should also be able to find the relevant documentation with the BADI itself in SE18. You would also need to do some minor customizing to choose which fields should be checked for duplicate values. You can find this customizing in the IMG customizing (transaction SPRO) (Just search for duplicate check and the search will find the relevant node in the customizing menu)
This should solve your problem.
Cheers,
Rishu.
