Method to expand a particular node in a HGrid

I have an enhancement where I create a child node under a parent node in a HGrid and once I create the child and come back to the Grid page I need to see the parent node expanded and child node visiible. By default the parent node is collapsed as a result child node is not visible.
Please suggest.
Also let u know if there is any api for expanding specific node in Hgrid

I have this same requirement and I am encountering java.lang.NullPointerException. This line works fine for finding the HGrid:
OAHGridBean oaHgrid = (OAHGridBean)webBean.findIndexedChildRecursive("SupHgridRN");
Either of these suggested methods:
oaHgrid.setExpandAllEnabled(true);
oaHgrid.setAutoExpansionMaxLevels(99);
results in the attached error stack. Any ideas?

How do i expand all the nodes in a jtree

Hi,
I am working on a project where i need to expand all the nodes of a jtree i have tried a few different ways but it never seems to expand all the nodes..
I would be very greatful if someone could point me in the right direction
cheers
Mary

you could use the following method that expands nodes recursively
expandNode( myTree, myRootNode, new TreePath( myRootNode ) );
public static void expandNode( JTree tree, TreeNode node, TreePath path ) {
    tree.expandPath( path );
    int i = node.getChildCount( );
    for ( int j = 0; j< i; j++ ) {
        TreeNode child = node.getChildAt( j );
        expandNode( tree, child , path.pathByAddingChild( child ) );
}

How to use xpath function to select some particular nodes

Dear experts:
does abap supports xpath to sellect particular nodes according some node value or condition, i know other programe language supports the function selectNode(xpath expression) , does abap or have the api to support it?
and i know there is a class support the xpath but it's not work., the class this:cl_xslt_processor
to clarify my point. i take a ex.
the xml doc is follow:
<?xml version="1.0" encoding="utf-8" ?>

i want to select the employee 's company name who empolyee id is 123
i use the method ,and the code is :

nsdeclarations = 'n0 http://gome.com/CRM/CRM/Outbound'
l_xslt->run('').
nodes = l_xslt->get_nodes( ).
LEN = nodes->GET_LENGTH( ) .
WRITE LEN.
but no nodes return.
is anybody knows what's wrong with it? or there is some other api to manipulate the xml dom.
best regrds!

Hello Kevin ,
i think you can get those details , have a look at program BCCIIXMLT1, i think this program will give you some idea to handle * manage xml docs.
along with that program ...you need to put filter
*---creating filers.
filter = document->create_filter_name( name = 'Company' ).
iterator = document->create_iterator_filtered( filter ).
main_node = document.
*---processing document.
perform print_node using main_node p_flag.
let me know if you need anymore help.

Display a particular node of Hierarchy in the Report.

Hi , all
I have an urgent requirement that i have to display only a particular node(5) of Hierarchy in the Bw Report , I have tried different options available in the Hierarchy tab (That is Expand to level 5 , Position of lower node - Above , Value of posted node - Hide ) . But stil it is displaying 5 and then 4 node , but i don't want that 4 node .
Can anybody gine me some useful suggestion .
Thanks in advance..

Hi Akash,
- To show only particular nodes of a hierarchy in the Excel sheet:
Step 1: include the base characteristic
Step 2: select the hierarchy (properties of the characteristic) - (display key only)
Step 3: user restrict (from context menu of the characteristic) on the nodes that you want to display.
Step 4: expand to level: 1 (properites of the characteristics)
This should serve the purpose. I know it is a little late, but it might be helpful in the future

When using numericupdown to expand/collapse treeView nodes. Why the collapse part is not working ?

I have a treeView in my form1 designer. The treeView variable name is: treeViewMS1
When i'm running my program the treeView is automatic expanded to level 1:
Now if i click on the numericUpDown and change the value to 2 then:
So the expanded part is working fine when i change of the numericUpDown by one up the expanded is working fine.
Now when it's on level 2 and i change the numericUpDown back to value 1 that's level 1 instead get back to my first screenshot Expanded level 1 it's getting back to the root level 0.
and i want that the collapse part will move only one level back but it dosen't matter if i'm on expanded level 2 or 3 or 5 it will allways jump to 0 to the root.
This is the numericUpDown value changed event:
decimal oldValue;
private void numericUpDown1_ValueChanged(object sender, EventArgs e)
if (numericUpDown1.Value > oldValue)
ExpandToLevel(treeViewMS1.Nodes, (int)numericUpDown1.Value);
else
CollapseToLevel(treeViewMS1.Nodes, (int)numericUpDown1.Value);
oldValue = numericUpDown1.Value;
ExpandToLevel method:
void ExpandToLevel(TreeNodeCollection nodes, int level)
if (level > 0)
foreach (TreeNode node in nodes)
node.Expand();
ExpandToLevel(node.Nodes, level -1);
And CollapseToLevel method:
void CollapseToLevel(TreeNodeCollection nodes, int level)
if (level > 0)
foreach (TreeNode node in nodes)
node.Collapse();
CollapseToLevel(node.Nodes, level - 1);

I solved it this way:
I solved it like this: In the Form1_Load event i did:
SetToLevel(treeViewMS1.Nodes, 1);
In my case i wanted it to begin by default in level 1.
Then in the numericupdown1 changed value event:
private void numericUpDown1_ValueChanged(object sender, EventArgs e)
SetToLevel(treeViewMS1.Nodes, (int)numericUpDown1.Value);
Then the method SetToLevel:
void SetToLevel(TreeNodeCollection nodes, int level)
foreach (TreeNode node in nodes)
node.Collapse(false);
ExpandToLevel(nodes, level);
And last the method EXpandToLevel:
void ExpandToLevel(TreeNodeCollection nodes, int level)
if (level > 0)
foreach (TreeNode node in nodes)
node.Expand();
ExpandToLevel(node.Nodes, level -1);
And now it's working perfect like i wanted it to work. When changing the numericupdown value it's changing the node tree expand/collapse levels.

Web Dispacher, deactivate a particular node how to?

Hi,
Is there any property that can be set in the Web dispatcher profile or the message server, which can stop sending any request to a particular J2ee instance in the cluster?
The business requirement is that one server (node) in the cluster should not receive any HTTP(s) request from the client, so that this server can be dedicated to run some application intensive routines.
One way that I have figured out is that we can deactivate a particular node from the Web dispatcher ICM web console, but this is not persisted and the settings go away when the web dispatcher is re started. How can I make it persist?
Thanks.

Hi Sukanya,
Did you ever resolve this problem? We too want to deactivate a server from the Web dispatcher. We also need to connect directly to it as you require. When we used Gary's method of Config Tool --> Server_ID####### --> Debug --> Debuggable --> Restricted Load Balancing, we are also unable to connect to that node directly.
I have read through the Web dispatcher online Help. The mention creating groups but they all seem to pertain to ABAP groups using SMLG. Our Web dispatcher is used in a stictly J2EE environment.
There must must be a Profile setting or some config to restrict specified nodes... Let me know if you have found out?
Thank You,
Jon Sells

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

Expanding a JTree Node on selection

Hi,
I have a need to expand the node on selection in a JTree. I would like all the children to be recursively expanded and selected.
I believe the code lies somewhere with in JTree's TreeSelectionListener.
The code I have is as follows
tree.addTreeSelectionListener(new TreeSelectionListener()
public void valueChanged(TreeSelectionEvent evt)
TreePath[] paths = evt.getPaths();
for (int i=0; i<paths.length; i++)
if (evt.isAddedPath(i))
DataNode node = (DataNode)paths.getLastPathComponent();
ArrayList aList = node.children();
if( !aList.isEmpty() )
for(int j = 0; j<aList.size(); j++)
TreePath tp = paths[i].pathByAddingChild(aList.get(j));
System.out.println(tp);
tree.expandPath(tp);
}//for
}//public void ValueChanged
This does not seem to solve the problem..
Your comments or help is very much appreciated..
thanks

Confining objects to a particular node in a distributed cluster

I have a partitioned cache for a cluster and there are n nodes(jvm instance) within that particular cluster. Both the data and backup data are randomly and evenly spread accross different nodes. Is there any way to put a constraint based on the cached object value (eg object with value >5) or the newly cached object should always reside in a particular node? Is partitioned near cache supports that facility? I want that object to be loaded in a particular user preffered node for the first time itself irrespective of where it is referred?

Hi,
there is support to a somewhat similar functionality, but it is impossible to exactly achieve what you want.
First of all, Coherence places and locates objects in the partitioned caches (distributed cache and near cache are partitioned caches) strictly based on the key. So it is impossible to achieve data placement based on any part of the value. Placement can depend only based on the key.
Second: when nodes come and go, data in a partitioned cache moves around with the granularity of these movements being the partition. There is a way to influence which partition a specific key ends up or rather to influence that certain keys end up in the same partition, but the placement of partitions on nodes is not static, it varies over time. However you can determine which node a certain partition resides at the time of asking. Of course it might change right afterwards :-).
So what you can do is you can ensure that groups of your keys end up on the same partition and hence they always reside on the same node.
To achieve this either your keys must implement KeyAssociation or you must define a KeyAssociator instance for your cache. When this is done, then you can optimize your queries and aggregations by using the KeyAssociatedFilter or PartitionFilter to execute only on certain nodes or partitions.
For more about this, look at the following Wiki page:

Forms Builder-hierarchical tree(expanding and collapsing nodes)

hi friends,
can anyone help me with populating my hierarchical tree form by using codes for collapsing and expanding?
for instance when_button_pressed:
tree_control.expand_all(tree_control.v_item_name); //this is for expanding all the nodes in the tree structure
well, i have an sql statement in my record group which in turn defines the structure of the hierarchical tree.
Is it possible to just use the codes 'tree_control.expand_all(tree_control.v_item_name);' like that in the when-button-pressed trigger?
Thanks for any help :)

Detection method for first time a Node is rendered

Hello,
I need to lazily perform some computation until after a particular Node is shown to the User. So if the app has multiple tabs, the goal is to not do work for a tab that hasn't even been switched to yet.
I figured the VisibleProperty of Node would help but it's not acting as I'd expect.
final BorderPane tab1 = BorderPaneBuilder.create().build();
setOnFirstShown(tab1, new Runnable() {
@Override
public void run()
    _log.info("Show 1");
    tab1.setCenter(new Text("1"));
final BorderPane tab2 = BorderPaneBuilder.create().build();
setOnFirstShown(tab2, new Runnable() {
@Override
public void run()
    _log.info("Show 2");
    tab2.setCenter(new Text("2"));
tabs.getTabs().addAll(
TabBuilder.create().text("One").content(tab1).build(),
TabBuilder.create().text("Two").content(tab2).build());Here is the listener:
public static void setOnFirstShown( final Node node, final Runnable response )
class Changer implements ChangeListener<Boolean>
    @Override
    public void changed( ObservableValue<? extends Boolean> obsVal, Boolean oldVal, Boolean newVal )
      _log.debug("Changed: " + newVal);
      if( newVal.booleanValue() )
        /** remove the listener b/c it's only used once */
        node.visibleProperty().removeListener( this );
        _log.debug( "Responding to first show for: " + node );
        try
          response.run();
        catch( Exception e )
          _log.error( "Failed to run response:" + response, e );
node.visibleProperty().addListener(new Changer());
}So each tab should replace its content with a Text when it becomes visible. However in actuality it works like this:
1. Scene launches, nothing displayed in the first tab. The visibility flag is set to false but not to true
2. Click on the second tab and its content correctly gets a change (to true) in visibility and the Text node appears
3. Click back on the first tab and now it gets visible set to true and shows the Text node
So it seems like for what is initially shown, the Nodes' visible flag is not properly set.
Does anyone have any insight or a better way to delay reaction until a given Node is actually visible to the User?

The visible property of a Node doesn't quite do what you think. From the javadocs:
Specifies whether this Node and any subnodes should be rendered as part of the scene graph. A node may be visible and yet not be shown in the rendered scene if, for instance, it is off the screen or obscured by another Node.
The default value of the visible property is true.
So, your first tab content originally has visibility set to true. You add it as the content of the first tab, and it remains true. Since it never changes, your ChangeListener is never invoked.
The second tab's content also originally has visibility set to true. When you add it as the second tab, it's visibility becomes false to indicate it should not be rendered. When it is selected, the visibility of the first tab content changes to false and the visibility of the second tab content changes to true, invoking the listeners.

How can i change the particular node color in Jtree?

I have constructed the tree.i dont know how to set the color for the particular node then how can i change the particular node icon depends on some conditions like if we will give the input whether it is available in jtree that node icon only changed.Anyone please help me as soon as possible.

i saw that tutorial.from that book i dont get the particular node cell renderer.i got a cell renderer for tree only.i attached my code in this mail.pls see and help me if u will do

Debug a particular node of SMARTFORM

Hai Fellas,
How to debug a particular node of Smartforms.
I dont want to debug it from the begining.
There is a restiction I can't add anything as the code is in Quality server.
i.e no break points can be hardcoded using program line.
Best Regards,
Suvendu.

Hi,
Just for debugging you cant write break-point statement and u cant transport,the best practice is go to smartforms ,there will be a option find the function module.Go to Se37 give the function module name,go to display mode,search for ur field or internal table or a work area,keep the break-point ,and then run the smart form ,this is way that we can debug in quality and production systems
Thanks

Since it's all text, why not use a real quick Match Pattern (or Regular Expression, but you don't need that much power here), see attached.
