Implementation of the hasProperties() method of the Node class

The following snippet of code prints:
false
true
which seems to be a bug.
TextField nameField = new TextField();
System.out.println(nameField.hasProperties());
ObservableMap<Object, Object> props = nameField.getProperties();
System.out.println(nameField.hasProperties());The implementation of the hasProperties() method in the Node class returns true, if the ObservableMap object for storing properties has been created. That is not what is expected from this method. I think, this method should also check if the ObservableMap has any properties.
Can someone confirm that it is a bug?
Thanks
Kishori

You can log it at http://javafx-jira.kenai.com and then, if the developers want to keep it the way it is (which they may for API compatibility purposes), they can at least document it so that a user would know what to expect without writing a test or making a potentially invalid assumption.

Overwriting a method of a super class in the subclass ???

Hi,
can somebody tell me whether it's possible to add a new implementation of a method in the sub class which is inherited from a super class?
I want to model my program in that way:
1. I define a super class with some implemented methods.
2. This class should be inherited in a sub class. One method should be used as it was implemented in the super class but another method should be overwritten in the subclass.
I know this concept from Java but I couldn't find a way how to do it in ABAP
Many thanks for any help!
Best regards,
Birgit

hi,
yeas you can do it,
Subclass can re-implement the inherited public and protected methods from superclass.Class C1 contains method METH1(public) and METH2(protected), both of which are modified and re-implemented in its subclass C2.also you can have ur own methods in subclass.Objects are created out of both classes and the method METH1 for both objects are called.
Output of the program demonstrates different behaviour for method METH1 of class C1 and C2.
This demonstrates the theme.

Is it possible to call a subscreen/modal dialog box from the global class

Hi,
Is it possible to call a subscreen or modal dialog box from the global class ..
or is there any option to display a pop screen or subscreen in order to get the values from user which as to be implemented
in the global class..
thanks and regards,
Poornima.

Hi Poornima,
you should follow Uwe's suggestion. The only alternative I can imagine is dynamic document in a dialog container. But I don't know any standardized classes to make use with minimum effort. Have a look at report DD_ADD_FORM_INPUT. Here they put the input field in a container control in a screen; you can put the container control on a dialog container (CL_GUI_DIALOGBOX_CONTAINER).
We will not get rid of any screen for the time being, but if your application is started from any screen, the DIALOGBOX_CONTAINER can start from there.

Clemens

Implements interface method at the derived class

Hi all.
I have a class (Derived) that extends another class (Base).
In the base class (Base) there is a method f() with its implementation.
In the interface (C) there is also f() method exactlly like in the base class (Base).
The derived class (Derived) is implements the interface (C).
My question is:
Do i have to implement the method f() in the derived class (Derived) ?

My guess is that you probably have to, even if it's just to call the parent's method.
This all sounds pretty sketchy. Why don't you just make the BASE class implement your interface?

How to implement the String class "split()" method (JDK1.4) in JDK 1.3

is it possible , with some code, to implement the split() method of the String class......which is added in JDK1.4 ..... in JDK1.3

how do i change the Node color in the JTree

What do you mean it doesn't help you? PhHein told you you need to use TreeCellRenderer and gave you a link to a tutorial, what more do you want? You need to create a class that implements TreeCellRenderer like:

boolean expanded, boolean leaf, int row, boolean hasFocus)If you want to be spoon fed, you need to pay for a tutor.

Binding with all the nodes to the table

Hi,
I have requirement like this,
I have table in which data is displayed using BAPI.
In my BAPI , there are four tables.
My criteria is to bind the values to the table from the four nodes which is mapped from BAPI.
But I can't able to bind the value form all the nodes, it allowing me to only bind form one node.
Please help me with the procedure to bind the values to the table from all the nodes in the context.
Thanks,
Anitha

Hi Anita,
I had a similar requirement and resolved my problem by following the below procedure. Try this, it might help you.
I have got 3 Nodes coming from a BAPI
Model Node Root--
       Model Node A---
          Attribute- 1
          Attribute- 2
      Model Node B--
          Attribute- X
          Attribute- Y
      Model Node C--
         Attribute- F
         Attribute- G
Now I want bind all these Nodes to one table. So, I created a "Value Node" - V under Model Node Root. Then create Value Attributes under Node -V with the similar names of the above Model Node attributes and then change their "Type" property exactly same as the Model Attributes Type.
Then, create a Table and then Bind the table to the Value Node. Now, in your wdDoinit Method of your Component Controller, give this code
WDCopyService.copyElements(wdContext.node<modelnode>, wdContext.node<valuenode>);
Later in your View Implementation give the following Code.
IPrivate<Name>View.ISourceValueNode iSourceValueNode= wdContext.nodeSourceValueNode();
IPrivate<Name>View.ISourceValueElement iSourceValueElement;
IPrivate<Name>View.ITargetRFC Element iTargetRFCElement;
for(int i=0;i<wdContext.nodeTargetRFC().size();i++){
iTargetRFCElement = wdContext.nodeTargetRFC().getTargetRFCElementAt(i);
iSourceValueElement = iSourceValueNode.createSourceValueNodeElement();
iSourceValueElement.set<attribute name>(iTargetRFCElement.get<Attribute name>());
iSourceValueNode.addElement(iSourceValueElement);
iSourceValueNode.moveNext();
I hope this helps you. Let me know if you need any information.
Regards,
Gopal.

I think your problem come from this method :

   System.out.println("Got transfered data");
   Object userObject = tr.getTransferData(TransferableDataItem.DEFAULT_MUTABLE_DATAITEM_FLAVOR);
//DefaultMutableTreeNode node = (DefaultMutableTreeNode)path.getLastPathComponent();
   IconNode node = (IconNode)path.getLastPathComponent();
   IconNode newNode = new IconNode(userObject);
   DefaultTreeModel model = (DefaultTreeModel)getModel();
   model.insertNodeInto(newNode, node, 0);
...You should write :
if (tr.isDataFlavorSupported(TransferableDataItem.DEFAULT_MUTABLE_DATAITEM_FLAVOR))
   IconNode node = (IconNode)tr.getTransferData(TransferableDataItem.DEFAULT_MUTABLE_DATAITEM_FLAVOR);
   IconNode node = (IconNode)path.getLastPathComponent();
   IconNode newNode = new IconNode(node);
   DefaultTreeModel model = (DefaultTreeModel)getModel();
   model.insertNodeInto(newNode, node, 0);
...and create a construcor for IconNode :
public IconNode(IconNode node) {
   super(node.getUserObject, node.getAllowsChildren());
   icon = node.icon;
}When you use IconNode newNode = new IconNode(userObject), the icon is null (see your constructor).
If I can say something, you should simplify your code : you can do the same thing dividing the size of your code by five (at less).

Database Connectivity takes long time if one of the Node is down .. ??

Hello All,
Env: 10.2.0.4 on Solaris 10
I have 2 nodes.
When Node1 server is down, it takes long time to connec to the database.
tnsping would give "OK(2050ms)". Below is the tnsalias.
RAC_test =
(DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST=20.268.169.123)(PORT= 1521))
     (ADDRESS = (PROTOCOL = TCP)(HOST=20.268.169.127)(PORT= 1521))
     (LOAD_BALANCE = yes)
          (CONNECT_DATA =
        (SERVICE_NAME = DK.com)
      (FAILOVER_MODE =
        (TYPE = SELECT)
        (METHOD = BASIC)
        (RETRIES = 180)
        (DELAY = 5)
)I put the trace on sqlnet.ora and found that first it pings to the "20.268.169.123",
since the Server is down there will not be any reply and this consumes the delay and
later it would ping "20.268.169.127" and connect to it.
If i keep "20.268.169.127" above "20.268.169.123" in tnsalias, and keep "LOAD_BALANCE=no",
it gets connected very fast, as its directly connecting to Node2. In tnsping i get Ok(40ms).
How do i reduce the connect timing if i use the first step. Why does it take long time for
Oracle Client to understand that the Node1 Server is down ?
TIA,
J J

I hope the IP's you are using in the TNS are Virtual IP's.
You must use Virtual IP's / hostnames for the failover to be quick. If Node 1 is not available then then it's (Node 1's) virtual IP would also get assigned to Node 2 hence all client connections are still able to get a response from the Node Virtual IP address without needing to wait for TCP/IP timeouts. This helps clients to get notified immediately that node 1 is unavailable and the connection tries the 2nd ip/host in the connect descriptor.
Hope this helps.

How to create input text of the node in AVL tree

Hi experts,
I create a simple AVL tree to display the sales order items, just two classes for one relationship. Like the left part on the screen in this program "DEMO_ABAP_OBJECTS_CONTROLS".
I want to let the node of the second class be maintained serial no., somthing like input field behind the node or double click the node, then show up the input field on another space on the same screen.
And there is a button on screen, I can do some check for the text of input field when pressing the button. If the input data is wrong , then show up the error message.
I have searched BCALV* in SE38, but i don't see anything helpful.
Plz give me some advice, thanks a lot!!
Regards,
Claire

To Kunjal and Uwe,
My AVL tree is declared like this:
Data: tree TYPE REF TO cl_gui_simple_tree.
The class is not "cl_gui_alv_tree" , so I can not use the code.
The code I create the node is the follwing:
CALL METHOD tree->add_nodes
EXPORTING table_structure_name = 'ABDEMONODE'
node_table = node_table.
And I looked the program that Uwe wrote, the tree is declared in class cl_gui_alv_tree, too.
I want to double click the node and appear a field that can be inputed text.
Is there any other way to do this with the class cl_gui_simple_tree?
Thanks for the advence help.

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 edit the node value of a tree in webdynpro java

Hi ALL
I have Tree UI element where i got displayed all the nodes by calling the BAPI
Now my requirement is when i put the cursor at any node in the Tree struture then on click of insert button i need to insert the new node with the text , the user has to be option to give new text for the new node dynamically , so while adding the new node in a tree the tree has to choose the text for new node , like how to edit the node of a tree to add new text.
If any one can send the sample code on the same then it would be great help to me.
Similar requirement like in table UI Like however we are adding the new row in a table when we click on the insert button then cursor will go to that new row in a table where user can enter his details in the table.. now i am looking for the same requirement in a Tree UI element.
is it possible the same requirement in tree UI element in webdynpro for Java??
Thanks
kallki reddy

Hi kallki reddy
In general I think this is not possible in the form you'd like. It seems the Tree control is read-only thing always. It cannot provide editing capabilities.
Table is different thing. You can select within many different cell editors including Input Fields.
I guess that you scenario could be implemented not with Tree control, but with Table with Master Column. The master column allows to bring up a hierarchy into a plain table. So it's just a tree inside a table.
Here you can find further details: [TreeByNestingTableColumn API|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/92/12a74046033913e10000000a155106/content.htm]

Calling the super class method from the subclass

Hi all,
I have a question about inheritence and redefinition of methods. Is it possible to call the superclass implementation of a method which is redefined in the subclass in another method of the subclass?There are possbilities like creation of an explicit super class instance or delegating the super class method implementation to another method which is also protected etc. What i mean is, is there a direct way of calling it?We have ,me, as the reference for the instance we have(which is the subclass instance in this case), is there also a way of pointing the superclass implementation(with super we can reference in the subclass redefinition, my question is if we have such a parameter in other methods of the subclass too)
Thanks in advance
Sukru

Hi,
The super reference can only be used in redefined methods to call superclass implementation . So probably what you can do is use upcasting and access the required superclass implementation. I can think of only this way...;-)
Ex data lr_super type ref to cl_superclass
lr_super = lr_subclass.
lr_super->method().

How to Restrict the node level in account hierarchy

Hi experts,
I want to restrict the node level in account hierarchy. I attached one example. in that if i click 6000 node again it want to show error message. for one parent node i want to create only two child node. Further if i create means it want to show error msgs and not allow to create the node..

Not able to display the Node context attributes to table

Hi Friends,
Issue: Currently i am reading the Node parameters and assigning the parameters to the Context of the mainView.
Then displaying the attributes into table here i am using a iterator to fetch the attributes.
But its reading only one record to the table not all the attributes.
Here i am attaching the code:
Node is EvaluationDimensions and attributes are Dimension and Selected_values.
Line: -
public void wdDoInit()
//@@begin wdDoInit()
try
IBONodeElement test = null;
test = (IBONodeElement)wdThis.wdGetDefinedimensiongafController().wdGetContext().nodeEvaluationDimensions().currentEvaluationDimensionsElement().model();
IBONode testNode = test.getBONode();
Iterator it = testNode.iterator();
IBONodeElement itElement = null;
while(it.hasNext())
itElement = (IBONodeElement)it.next();
//wdContext.nodeEvaluationDimensions().createAndAddEvaluationDimensionsElement();
wdContext.createAndAddEvaluationDimensionsElement();
wdContext.currentEvaluationDimensionsElement().setDimension(itElement.getAttributeValue("KPIParameterDefinitionName").toString());
wdContext.currentEvaluationDimensionsElement().setSelected_Values(itElement.getAttributeValue("ParameterSelectedValuesText").toString());
} catch (RuntimeException e) {
e.printStackTrace();
wdThis.wdGetDefinedimensiongafController().wdGetAPI().getComponent().getMessageManager().reportSuccess(e.toString());
//@@end

Could you suggest me some alternatives to show all records into table??

Hi Prabhu
IBONodeElement test = null;
test = (IBONodeElement)wdThis.wdGetDefinedimensiongafController().wdGetContext().nodeEvaluationDimensions().currentEvaluationDimensionsElement().model();
What is this model() .
You remove the try catch method once and test it to trace the error.Why cant you use typed AccessAPI to fetch the values from the node element.Is your node have more elements test it.By getting the size of the node.
That too you are setting values to only current context element .Not for other elements.Everytime you are setting the values to current context element,thats why you are getting only one element values at a time.Iterate properly and try to set the values for each element
wdContext.currentEvaluationDimensionsElement().setDimension(itElement.getAttributeValue("KPIParameterDefinitionName").toString());
See the above code every time you are setting to currentNode lement notforother elements.
