Netbeans beans binding

__How TO Bind The Domain object Directly To Detail View ?__
when we create master detail table with netbeans .netbeans uses the following binding patern.bind the list to master table and master tables selected element to lists domain object
how to use netbeans beans binding feature create a from which only have detail view (no master table )
and bind domain (customer) object directly to GUI fields
and i should have to the abilty to add new (create new ) domain object using the same form.
I dont want jtable in my form
note:-and I have to be able to persist the old object and create new object in the same form
ie :- add new button on the same form
please visit following link for picture
[http://netbeans7.blogspot.com/]

I'll give my usual comment here:
Take this to a NetBeans forum--since it's how to use the NetBeans GUI tool and hasn't anything to do with you coding Java--or go back and learn how to code GUI's without an auto-coder. I and many others are very reluctant to give any advice other than that to anyone that wants to use the auto-code features of a product.

PB with beans binding in a netbeans 6 java project with ant script existing

Hi all,
I am using netbeans 6.01.
I want to use beans binding in a simple swing form created with Matisse designer. If i do beans binding in a Netbeans java project with existing ant script i have the following error :
java.lang.UnsupportedOperationException: No PCPE/PCPMI found for classpath/compile in MasterFileObject@25 .... etc
Beans binding works very well in normal java project ( Java Desktop App for instance ).
How can i make it work in an existing java ant script project ?

You need to add the Beans Binding (beansbinding-1.2.1) that come with NetBeans 6 in your projects class path.

Bean Binding with Netbeans - JTable

Hi all,
I am using Netbeans to bind properties of my Java bean against particular fields in my UI...For example a text field is modified the bound bean property is automatically updated which is working fine.
Now I have a JTable and within this I want to bind the first column (e.g. name) against a property in my bean...I cannot see how to do this in Netbeans, has anyone got any advice?
Thanks,

You didn't reply to Andre_Uhres' response in your last thread on the same topic. Why should we think things will be any different in this one?

Beans Binding: JList + Converter = convertForward not called

Hello,
I'm having difficulty getting beans binding of a JList selectedElements to work with a converter.
I have a master detail generated app in Netbeans 6.1 b1. When I select the master table, my detail elements are all updating nicely except for a JList. The source property is a String (CSV) which I would like to run through a converter to turn the CSV into a List that the JList selectedElements can use. Unfortunately the converter's convertForward method is never called. If I select items in my JList, then the converter's convertReverse is called however the underlying source value is not updated. I'm obviously missing something here (either code or understanding!), could anyone please help me?
Best regards,
Chris.
The code is as follows:
Converter:
import java.util.*;
import org.jdesktop.beansbinding.Converter;
public class AdditionalFeaturesConverter extends Converter<String, List<MyEntity>>{
    @Override
    public List<MyEntity> convertForward(final String csv) {
        // will implement once I get this called ;)
        return new ArrayList<MyEntity>();
    @Override
    public String convertReverse(final List<MyEntity> selected) {
        final StringBuilder csv = new StringBuilder();
        for (MyEntity entity : selected) {
            if (csv.length() > 0) {
                csv.append(',');
            csv.append(entity.getId());
        return csv.toString();
Netbeans generated code. Note: the EL worked perfectly for the default generated String -> JTextField binding.
private void initComponents() {
       binding = org.jdesktop.beansbinding.Bindings.createAutoBinding(org.jdesktop.beansbinding.AutoBinding.UpdateStrategy.READ_WRITE, masterTable, org.jdesktop.beansbinding.ELProperty.create("${selectedElement.additionCashbackFeatures}"), jList1, org.jdesktop.beansbinding.BeanProperty.create("selectedElements"));
        binding.setConverter(new testapp.AdditionalFeaturesConverter());
        bindingGroup.addBinding(binding);
}

There is definitely something strange going on here.
When I select from my master list, the binding does not set the selected items in the JList. In fact, the opposite is true - when I select from the master table and the newly selected property is overwritten with the last selection state of the JList.
Has anyone seen this before?

Help - Bean Binding an SQL join to a gui component(jtable) in Netbeans?

Good afternoon. I'd like to ask if there is a way to data bind an SQL Join from 2 or more tables to a
GUI component(Jtable) in Netbeans. All the tutorials show is how to bind all the fields of 1 database table
to the component. Under the BIND/ELements option the IMPORT DATA TO FORM menu only allows
you to choose 1 among the database tables from a selected database.
Is there a way to configure an SQL query and attach it to the component?
Thanks.

This is not a Swing problem. Try a NetBeans forum.

Remove unwanted backing bean binding

Hi All,
My JSFX page has around 200 fields and I have to manipulate only a few fields in the backing bean. When I use this method to bind the UI components with the backing bean Design--> Page Properties ---> Component Binding ---> Auto Bind, all the page UI components get bound. This creates unnecssary binding and my backing bean java files becomes quite messy and runs into 5000 lines. Is it possible to remove the unwanted ones manually without causing any harm. What's the best practice by the way.
Thanks

Hi,
This creates unnecssary binding and my backing bean java files becomes quite messy and runs into 5000 lines
This exactly is why the auto-generate option for backing beans is disabled by default in JDeveloper. There is no functionality in the IDE to remove unneeded bindings (how would the tool be able to tell what you need and what you don't need given that managed beans can be referenced from other managed beans and are referenced from EL in the component binding property).
Best practices for working with backing beans is to not create them by default and instead use managed bean that you turn into backing beans (which is when they have a page component binding reference) only when needed. This way you stay in control
Sorry, I have no better answer for this

Beans Binding with JTable Problem

Does anyone have an idea on how to make the columns of a JTable (with binded elements) not editable? I'm currently using the binding feature of NetBeans 6.0 M9.

Override the tables isCellEditable method to always return false.

Update of JTable after inserting row with beans binding

I have a little problem. When i create a little app with netbeans which uses the beansbinding with a table it is not possible to get updates of the list into the table.
i use nearly the same methods as if i create a database application with the wizzard. The only difference i see (so far) is that i don't use the Swing application framework.
if i try to repaint the table or the ScrollPane, nothing happens. The list is changed but not the table....

You should be updating the TableModel, not the "list". When you update the model it will notify the table to repaint itself.

Netbeans Bean Form

Hi,
I created a class (MyPanel) using the JPanel Form.
I added some Component (JButton, TextField..)
I added it under Bean the Palette Manager so I can reuse it.
I created a class (MyCustomPanel) using the Bean Form and deriving from MyPanel.
I got the following error:
Error in loading component: [MyPanel]
Failed to initialize layout of this container.
MyPanel is working perfectly fine if I add it to another JPanel instead of inheriting from it.
So my questions are:
How to use the Bean Form?
Am I using it as it is meant to?
Is the Bean Form what I should use to derive from a panel and be able to use the Design view
What could be causing the error with the layout?
Thank you.

To make it a Bean, you must implement java.io.Serializable, and add getXXX and setXXX methods for your private variable foobar. As a bean, the code you've provided would look kinda like this:
class SampleJCB
      extends JComboBox
            implements Serializable {
    private int foobar = 0;
    public SampleJCB() {
        super();
        foobar = 15;
    public int getFoobar(){
        return foobar;
    public void setFoobar(int foobar) {
        this.foobar = foobar;
}Now, if you're interested in persistance of you're ComboBox, you may want to check out the Serializable Fields API, which will give you the details on how to serialize objects, how to write readObject and writeObject methods, how to define which fields are default serializable, etc.
Another thing you should note is that all swing components are already beans. So, JComboBox is itself a bean, and hence, when you create a subclass of JComboBox, it is, in a way, already a bean.

Typesafe and refactoring friendly bean binding alternative to jGoodies?

I've just read some jGoodies docs. It seems poewrful but it does have a problem: property names have to be specified as strings, so the compiler cannot enforce static type checking and refactoring becomes a nightmare.
PropertyConnector pc = new PropertyConnector(bean, "value", uicomp, "value");I'm surprised no one has invented something better yet, and I hope it was my fault when I searched for it. I mean, if you can get a Class reference from the language with
MyBean.class;it seems obvious you could do the same also with field members of a class, something like:
java.lang.reflect.Field myBeanProp = MyBean.fieldname.field;I understand that this would require the compiler to understand each field name as a keyword, and also that the above syntax is somewhat ambiguous, but I guess those problems can be worked around by using a new single fixed operator with two arguments, name it "property", something like the instanceof operator. I imagine something like:
java.lang.reflect.Field myBeanProp = MyBean property fieldname;This way refactoring can take place with standard IDEs tools and the Field instance has more chances to carry enough static type informations than a String so that the compiler can enforce type checking.
Do you know if something like this already exists? Do you know if JSR 295 is going to address these issues? If it does not, what do you think about this idea?
Your feedback is very appreciated.

Hi user404,
I am unable to instamtiate this class:
Warper warp = new Warper();
I think it should be Wrapper warp = new Wrapper ();
But still I am unable to instantiate this as well.
Do I need to create superate Wrapper.java class?.
I tried serializing AppModuleLocalImpl implements Serializable, it throwing java.lang.InstantiationException.
please suggest.
thanks,
VeereshOw yes, my bad. It should be Wrapper.
If you make a normal java class named Wrapper and paste the code provided by dario you should be able to make a Wrapper object in your AppModuleImpl.
You could also return a string (since your output param is VARCHAR) instead of Wrapper or Object since String is seriazable (if you can't get the Wrapper object working).
Trying to make your AppModule seriazable is not a good idea.

I face same problem,,
the reason behind it is the user and password for the connection should not be blank...
and I resolve it in this way
1. Go to Source Packages > META-INF
2. Open persistence.xml as plain xml
3. Change the value of the following properties to any thing except blank one of them should be blank thus you got the exception
<property name="toplink.jdbc.user" value="app"/>
<property name="toplink.jdbc.password" value="app"/>
4. Run and have a fun!

JTable renderering/binding

I have a couple questions:
1. I need to put buttons in some of the cells... add/copy/delete that particular row. how do you track what row button was clicked? so i can access that data in my tablemodel and update the db.
2. how do you bind jtable editable fields? for example, in another project i had a jdialog, and i binded all jtextfields to my domain objects, and when anything changed it enabled a save button below (worked really well!). How can i do that with jtable?
Please ask to clarify if neccessary.

The v6 of NetBeans supports the new jsr 295 for beans
binding. This version is not final yet, though:
http://www.netbeans.org/community/releases/60/index.ht
ml
http://www.netbeans.org/download/flash/netbeans_6_gui_
builder/netbeans_6_gui_builder.html
-PuceThanks puce, yeah I read a lot of good things about JSR295, and I'm glad their moving towards integrating binding into swing, it's a key component to desktop applications.
But my question isn't necessarily the technology for binding, but instead from a design point of view.

How to bind scroll positions

Hi all.
Do you know how to synchronize scrolling between to JScrollPane containers (for example, in a JSplitPane) using beans binding (in a NetBeans IDE)?
Thank you in advance.

Thank you very much, that code works just fine:
BoundedRangeModel brmMaster = topScrollPane.getHorizontalScrollBar.getModel();
bottomScrollRange.getHorizontalScrollBar.setModel(brmMaster);Thank you!

Binding properties of a root node and using fx:include.

I posted a downloadable example of this here:
https://dl.dropboxusercontent.com/u/8788282/binding-test.zip
I've noticed some understandable, but less than perfect behaviour with the way FXML initialization is done when using fx:include. I find it's difficult to bind properties that belong to the root node of the included view without shooting yourself in the proverbial foot. Here is an example of what I mean:
sample.Main
package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("MainView.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    public static void main(String[] args) {
        launch(args);
sample.MainController
package sample;
import javafx.fxml.FXML;
public class MainController {
    @FXML
    void initialize() {
        System.out.println("MainController initialized.");
sample.MainView (FXML)
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.*?>

            fx:controller="sample.MainController">

    @FXML
    void initialize() {
        label.visibleProperty().bind(Bindings.createBooleanBinding(() -> true));
        /* When used as part of an fx:include, this controller's initialize()
         * block is called and the below binding is performed. After that, any
         * property values set via the containing view (MainView) are applied.
         * In this example, the MainView attempts to set the visible property
         * of this included view (fx:id="sub"). Since the visible property of
         * the root node (anchorPane) has already been bound, the error
         * "A bound value cannot be set." is given.
        anchorPane.visibleProperty().bind(Bindings.createBooleanBinding(() -> true));
        System.out.println("SubController initialized.");
sample.SubView (FXML)
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>

              AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0"
              AnchorPane.topAnchor="0.0">
            <children>
                <Label fx:id="label" text="sub view"/>
            </children>
        </VBox>
    </children>
</AnchorPane>
The comments in the initialize method of SubController explain what's happening. I found it a bit confusing until I figured out what was going on. Should FXMLLoader be checking to see if a property is already bound before trying to set it, at least for nodes declared via fx:include?

Hi Gaurave,
We need to show the report like this to some users, thats what the requirement is. Using the Posted nodes option does not help.

Clearing up a backing bean's property values.

Hi All
I saw a few similar posts from the past on this forum similar to my issue but couldnt make much sense of them. Therefore appologies for any repetition :)
I have search jsp/jsf page. And have one session scope backing bean associated with it. There is a cancel/Back button on the jsp page that takes the current user back to the previous page.
The problem is that if the user entered some search criteria in the UI components that criteria is retained in my backing bean when the user revists the page. I want my bean's properties to be cleared up once the user leaves the page.
I would prefer not to set the scope of my backing bean to request.
One solution i can think of is to set all the properties to null before leaving the page. (I have not tried it yet as I am actually posting from home after coming back from work :) )
Could you guys advise any more elegant solutions that could possibly solve this issue?
many thanks

Set the beans propertie values to null in the constructor [If it is in pagecode]
and in the jsp use binding
Like for example:in the constructor of the pagecode
public Some(){
if((getFacesContext().getExternalContext().getRequestParameterMap().isEmpty()) || (getFacesContext().getExternalContext().getRequestParameterMap().containsKey("parkPlanFrm:prePlanName"))){
ValueBinding vb = getFacesContext().getApplication().createValueBinding("#{bean}");
Bean pcBean = new Bean()
pcBean = (Bean)vb.getValue(getFacesContext());
pcBean.getParkPlanCountyMenu().setSubmittedValue("select");
pcBean.getParkPlanCountyMenu().setValue(null);
vb.setValue(getFacesContext(), pcBean);
IN THE JSP:
<h:inputText id="parkPlanPpn" styleClass="inputText" maxlength="15" size="15"
value="#{bean.prePlanNumber}" binding="#{bean.parkPlanPpn}" size="15">
</h:inputText>
Here *value="#{bean.prePlanNumber}"* is from the Managed Bean
*binding="#{bean.parkPlanPpn}"* is from PageCode
