Help on Deleting Node in Tree?

I'm trying to delete a node on a tree and some weird stuff is
occurring. Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
initialize="init();" layout="absolute">
<mx:Script>
<![CDATA[
private function click () : void {
if (MyTree.selectedItems.length > 0) {
var items:Array = MyTree.selectedItems;
for (var i:int = 0; i < items.length; i++) {
var nodeToDelete:XML = XML(items
var xlcParent:XMLListCollection = new
XMLListCollection(nodeToDelete.parent().children());
var iIndex:int = xlcParent.getItemIndex(nodeToDelete);
xlcParent.removeItemAt(iIndex);
]]>
</mx:Script>
<mx:XMLListCollection id="MyDP">
<mx:XMLList>
<root label="Default Policy">
<node label="node1"/>
<node label="node2"/>
<node label="node3"/>
<node label="node4"/>
<node label="node5">
<node label="node1"/>
<node label="node2"/>
<node label="node3"/>
<node label="node4"/>
<node label="node5">
<node label="node1"/>
<node label="node2"/>
<node label="node3"/>
<node label="node4"/>
</node>
</node>
</root>
</mx:XMLList>
</mx:XMLListCollection>
<mx:Tree labelField="@label" id="MyTree"
dataProvider="{MyDP}" x="141" y="109" width="528" height="440"/>
<mx:Button click="click();" x="141" y="557" label="Delete
Selected Node"/>
</mx:Application>
For some reason when I expand all the nodes and try to delete
one of the great grand children all of the great grand children
shift over as if they are siblings of the node that I deleted the
great grand children from.
Anyone have some good ideas? I sure wish deletion of nodes
was as easy as in actionscript 2.0

There a quite a few posts about this problem here already -
it seems to be a tree rendering bug (seems to come in various
different flavours).
The safest work around after fiddling with the nodes in the
tree is to get the axe out and reassign the data provider. To be
nice to the user, you might want to keep the expansion state (this
may not work if you made big "structural" changes to the tree).
The following works for me (after your changed the tree data
model):
var openItems:Object = treeopenItems;
tree.dataProvider = tree.dataProvider;
this.openItems = openItems;
Hope this helps.

How can i add and delete node in tree in run time

i want to know the method that let me select tree node to delete it and another to input upon user inputs

Hello,
why don't you just enter "add tree node" in the Search Forum search box ?
There are plenty of samples.

Adding Node and Deleting Node in Tree

Hi,
I am building a tree dynamically.
I have a class which has set of properties.I am constructing as follows.
public class TreeNode
 public function TreeNode()
 public var friendlyName:String;
 public var icon:Class;
 [Bindable]
 public var children : Array;
 public var logicalName:String;
 public var neType:String;
 [Bindable]
 public var arrayColl:ArrayCollection = new ArrayCollection();
 public function addChild(node:TopoTreeNode):void
 if (this.children == null){
 this.children = new Array();
 children.push(node);
 arrayColl.source = children;
 public function clearChild():void
 children = null;
 public function removeChild(arrayIndex:int):void
 if(children != null)
 children.splice(arrayIndex,1);
 arrayColl.source = children;
Then I set the dataProvider as follows where treeModel is object that is injected.
<mx:Tree id="tree"
 dataProvider="{treeModel.rootNode.arrayColl}"
 labelFunction="{treeModel.getDisplayName}"
 iconFunction="{treeModel.setIcon}"
 width="100%"
 height="95%"
 rowCount="6"
 showScrollTips="true" showDataTips="true" dataTipFunction="{treeModel.getDisplayName}" allowMultipleSelection="true" click="treeModel.displayItemInWorkingView(tree.selectedItems);"/>
TreeModel has the following variables
 [Bindable]
 public var rootNode:TopoTreeNode = new TopoTreeNode(); // this is the rootNode.
 [Bindable]
 public var rootChild:TopoTreeNode = new TopoTreeNode(); // this is the child of the root node..
While constructing the tree, it is working fine.
But after this when i try to add a node (ie adding a node as child to rootNode), it is getting added to my rootNode object but it is not getting displayed
When i click on the items in the tree or click on the drop menu in the tree it is getting displayed.
But i want it to be shown in the tree without clicking anything.
Could anyone help on this?

Srini

Off the top of my head, you need to call a refresh of some sort, or executeBindings()... something like that.
You will also need to start at the root node and expand any parent branches down to the new leaf.
If you are still having trouble after looking into that, I can try and dig through some of old code and find my solution.

Deleting nodes in tree structure

Hi All,
I have created a classical tree strcuture. Now I need to implement a delete functionality. This should delete all the nodes that are selected. If the node is a parent node, then, when I press the delete button, I should find both the parent and the child nodes deleted. How do I build a logic for this. Any help

you can read the table node_table with nody key value which imports when docubble click the the tree node (Double clifk event).

Program to add node / delete node in the tree control via abap object

Hi all,
i am new to abap objects.
Can anyone help me out to give program about add node , delete node at
a particular point in tree hierarchy.
folder1 -- level 1
subfolder1 -- level 2
*********subfolder1 -- level 3
*********subfolder2 -- level 3
subfolder2 -- level 2
folder2 -- level 1
if i select level3 and click on ADD button .....i get a facility to add new node
at level 3 and and same thing can happen at level1 and level2 ............ if i select
and folder at level3 and click on delete button ....it should delete that folder...
if you do not have such program ........then guide me how to achieve this target via object oriented because i have to split the screen also and have to show some alve display in that.
just guide me how to add and delete node at a particular level in tree structure....
thanks in advance........

Help needed in deleting nodes from RAC database

Our DB is 10g RAC database and the servers are Window 2003 server. Initially the database was configured to have 4 nodes. For some reason we stopped the instances in the first two nodes and the current database is running on node3 and node4. I queried the v$thread view and it shows 3 records. Thread 2 is closed and disabled. Thread 3 is open and public and thread 4 is open and private. Now we need to disconnect nodes 1 and 2 from RAC db and cluster ware (We use Oracle cluster ware) and plan to use those two servers for other purposes. Although I read through the Oracle doc regarding deleting node from RAC “11 Adding and Deleting Nodes and Instances on Windows-Based Systems” and wrote down the steps we need to take but I am still not comfortable in doing it since it is production env and we don’t have any dev env to practice those steps. So I would like to borrow your experiences and your lessons learned while you were doing those. Please share your thoughts and insights with us.
Thank you so much for your help,
Shirley

what's your full version? I can warn about specific issues in 10.1.0.3 and 10.2.0.1 - for example, in some cases (depending on how the listener was configured), it will be impossible to delete the listener for the deleted node. Known bug.
To avoid many many known bugs, you may want to upgrade to at least 10.2.0.2 before removing a node (from my experience, this is the first stable RAC version).
In any case, deleting a node is a rather delicate process. I really really recommend practicing. Take any pc/laptop, install VMWARE, define two virtual machines, install RAC and remove one node. It will take you an extra day or two, and could save your production.

Help in getting current expanded node in Tree UI

HI,
I have a requirement to build a tree dynamically. On expanding each node I need to create sub nodes inside that. But it is always creating inside the node where the lead selection is and not inside the current expanded node. Even though I have used getTreeSelection () to get the current element.
Detailed description about the application.,
I have created a context with the following structure,
TreeNode (0..n)
|
|--> ChildNode (recursive SiteTree)
|--> Name (string)
I have created a Tree UI Element in the view and inserted a node type 'TreeNodeType'.
I have set the properties of the inserted node type as given bellow,
Value Attribute in TreeNode -> Name I have assigned to 'Text' property of 'TreeNodeType'.
Initially I have created four nodes in the init() method ., using the following code :
for(int i=0;i<3;i++)
IPrivateTestTreeView.ITreeNodeNode treenode=wdContext.nodeTreeNode();
IPrivateTestTreeView.ITreeNodeElement treeelement=wdContext.createTreeNodeElement();
treeelement.setName("Testroot:"+i);
treenode.addElement(treeelement);
Now I need to create sub-nodes for this dynamically.,
I have created an action and called it in 'onLoadChildren' event of 'TreeNodeType' with the following code:
public void OnCurrentSelection()
IPrivateTestTreeView.ITreeNodeElement el = wdContext.nodeTreeNode().getTreeSelection();
wdComponentAPI.getMessageManager().reportSuccess(el.getName());

Where this returns me only the name of LeadSelection node and not the node which i try to expand. 
Is there anyway I can get the currently expanded node., Kindly help me out in this.
Points will be rewarded for helpful answers. Thanks in advance.
Regards,
Nirmal

HI Ayyapparaj ,
First I would like to thank you for your reply.
So it means that we cannot identify the currently expanded node in tree UI element and It will always be the lead selection node we will be able to get rite?
Can we make the current lead selection to currently expanded node 'By Default'?
Coming back to your solution.,
I created a context element 'isExpanded' of type boolean inside the TreeNode.
You said that there will be a call made to 'getter and setter' methods while we expand the node and we can set the lead selection to that element from there.
Could you please give me some more details of how to achieve it.
Thanks in advance.

Nirmal G

then employee name as a child of department
Initialy its working fine ,user can add edit and delete any node
In add and edit option I have no problem but in delete I hava a problem
when I am deleting any child node and after deleting the node I am clicking on the root node of the deleted node the it gives me null pointer Ecxeption .
but user added any child node and then delete it then Application work properly .
What is the problem I can't Understand please help me
thanks

Help needed in constructing a tree

Help needed in constructing a tree. I was wondering if some one can suggest me how to add messages in the second column for both the parent node and child elements.
I was able to create a tree succefully, but want to add some description in the second column for the first column elements, for both parent and child elements.
Please suggest me how to add the arrays to second column for parent and child nodes.
Solved!

The Child Text parameter is the one you are searching for. It accepts a 1D string array for the following columns.
hope this helps,

I deleted nodes with the web developer and the deletion has become permanent. How to undo?

I was trying to remove all the "Recommended Pages" etc. garbage on the right-hand side of Facebook and got a little click happy with 'delete nodes' using the Web Dev tools - as cathartic as it was! :)
Now it seems as though I have broken FB on Firefox (seems to work fine on IE, surprisingly) as pics seem to be missing and the left-hand menu as well - but, of course the stuff I was trying to rid myself of comes back just fine ... sigh.
I've read that all changes are supposed to be temporary until you restart the browser but this hasn't helped at all and I did try unchecking the 'Use hardware acceleration when available' that I read somewhere else, to no avail.
Any assistance that can be rendered would be very much appreciated.
For the record, I've learned my lesson and won't futz around with this anymore! :)

For a node deletion in the Inspector tool,revert that by reloading the page. If that isn't working for you, you could try Command+Shift+r to reload the page bypassing the cache.
You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.
HT > Profile Directory: Open Containing Folder
http://kb.mozillazine.org/Profile_folder_-_Firefox
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

How to fill or bind data using Value Node in Tree Node

Hi Gurus,

Thanks in advance.

TRY.
          lv_child = me->node_factory->get_proxy(
                    iv_bo = lv_value_node
                    iv_parent_proxy = me
                    iv_proxy_type = 'ZL_CLASS_CN02' ).
          lv_child->is_leaf = 'X'.
          APPEND lv_child TO rt_children.
        CATCH cx_sy_move_cast_error cx_sy_ref_is_initial.
      ENDTRY.
In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data. After/before this, you would need to build table and refresh in do-prepare_output of IMPL class.In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data. After/before this, you would need to buid table and refresh in do-prepare_output of IMPL class.
ztyped_context->resultlist->build_table( ).
IF ztyped_context->resultlist->node_tab IS INITIAL.
    ztyped_context->resultlist->refresh( ).
ENDIF.
Also the EH_ONEXPAND has to be implemented and event handled in DO_HANDLE_EVENT. But this expand event has to be delegated to context node directly as CL_BSP_WD_CONTEXT_NODE_TREE will already have the implementation.
ztyped_context->resultlist->expand_node( lv_event->row_key ).
Where in result list is the node ZL_CLASS_CN00.
After typing the whole content , i found this blog :). There are few things i have written more that in the blog. /people/poonam.assudani/blog/2009/06/24/create-a-tree-view-display-in-crm-web-ui
