How to call a method defined in AM when I select a value in LOV
Lets say there is a LOV. The scenario is as soon as I select a value in LOV, a method should be called I wrote in the AM. And the output of the method in an output text area.

I am not able to understand how to call a method when the user selects a value from the LOV.

This is wht I did. I had created the connection for the method. One replaced the property autosubmit to the LOV for real and in the properties of the output area, in partial submission trigger property, the ID of the LOV. But I don't have any place where I need to call the method. I'm also not able to remove a listener for action on the LOV

Call a method to support bean after selection to select only one option
Hi all

I'm new to Jdeveloper 11 g, and I'm trying to trigger a method once the user makes a selection on a 'select one choice' (JSF page).

I have a (backing bean) method that reads the selection and runs a procedure that retrieves data and that fills the input text A and B, unfortunately this is implemented using an af: button and I would that this method to trigger automatically after the user makes the selection without clicking the button. Can you help me?

Thank you

Use valueChangeEvent and selectOneChoice autoSubmit = 'true '.
```
    public void selectOneChoice1_valueChangeListener(ValueChangeEvent valueChangeEvent) {
        if(valueChangeEvent.getNewValue() != null)
     ......

How to call a method of the AM with parameters of Bean managed?
Hello world

I have a situation where I need to call the Managed bean (setDefaultSubInv) AM, under value changes Listner method. Here's what I do, I added the AM method on page links, and then at the bean call it

Class [] paramTypes = {};
Object [] params = {};
invokeEL ("#{bindings.setDefaultSubInv.execute}", paramTypes, params);

It works and be able to call this method, if there are no parameters. Say that I pass a parameter to setDefaultSubInv(String a) method AM, I tried to call it bean but raise an error

The string available = 'test ';
Class [] paramTypes = {String.class};
Object [] params = {DISP};
invokeEL ("#{bindings.setDefaultSubInv.execute}", paramTypes, params);

I'm not sure this is the right way to call the method with parameters. Can anyone tell how to call a method of the AM with bean to manage settings

Thank you
San.
Just do the following

1. your method in the Client Interface.
2 - Add to Page Def.
3 - Customize your Script like below one to reach your goal.

BindingContainer links = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap () .put ("username", "oracle");
operationBinding.getParamsMap () .put ("role", "F1211");
operationBinding.getParamsMap () .put ("Connection", "JDBC");
Object result = operationBinding.execute ();
If (! operationBinding.getErrors () .isEmpty ()) {}
Returns a null value.
}
Returns a null value.
}

I hope it helps you
Thank you

How to call a method when it is clicked on selectBooleanCheckbox?

Hello experts!

I use Jdev 12.1.2 and I'm currently calling a method in a Bean managed using an af:button and works great:

<af:button id="b1"
         icon="/images/icons/highlighted.png"
         actionListener="#{backingBeanScope.pppProjectsBean.toggleHighlighted}"
         text="#{sessionScope.highlighted_only ? 'Show All' : 'Show Highlighted Only'}"
         immediate="true"/>

My requirement is to change the button for a selectBooleanCheckbox, but the attributeChangeListener method is not executed:

<af:selectBooleanCheckbox text="Show Only Highlighted Projects"
   label=" id="sbc1"
   attributeChangeListener="#{backingBeanScope.pppProjectsBean.toggleHighlighted}"
   immediate="true">

What are the 3 codes methods in the managed bean:

    private void toggleHighlighted() {
        <code tested and working fine>
    }
    //For the action listener of the button

    public void toggleHighlighted(ActionEvent actionEvent) {   
        toggleHighlighted();
    }
   //For the attribute change listener of the checkbox    
    public void toggleHighlighted(AttributeChangeEvent attributeChangeEvent) {
        toggleHighlighted();
    }

Thanks in advance,
Jose.

Use valuechangeListener.

question on "How to call a method once when starting the application"
Hello everyone.

I'm trying to implement that article "How to call a method once when you start the application" by Frank suggests.
https://blogs.Oracle.com/jdevotnharvest/entry/how_to_invoke_a_method

Suppose I want to have a single entry point, so in my login.jpsx I have the below:
```
<f:view beforePhase="#{login.onBeforePhase}">
```
In the 'onBeforePhase' method, I have to pass the phaseEvent, since the signature is as follows:
```
public void onBeforePhase(PhaseEvent phaseEvent)
```
But how do I know the phaseEvent during the call to the login.onBeforePhase? How the call should be?

Thank you very much!

PS. I use jDev 11.1.2.1.0
You must not pass something to this method, this method is called before each Phase except view restoration
Just write logic as Frank suggested to the phase in which you want the code to run. You can get the PhaseId analogues

PhaseId.RENDER_RESPONSE
```
public void onBeforePhase(PhaseEvent phaseEvent) {// from Frank's doc
 //render response is called on an initial page request
  if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
... etc
```

ADF7,
the subject of the post has nothing to do with the question (for as far as I see it).
As you can see the error message clearly comes from the procedure pl/sql you call the application module, works of groovy appeal method.

We cannot decide what makes your service if you pass null as a parameter. You can check the settings before you proceed to the procedure or write the procedure in how it treats null parameters.

How to call a method of the Module of the Application of a class of ViewObjectImpl?
Howdy,

With the help of Studio Edition Version 11.1.1.3.0.

I have a setup where a user between an element and a price. When the item and the price is committed, I want this event to then influence the price of his parents. My idea is to do a ViewRowImpl class and then call an AppModuleImpl class that is her parents and it affects their attributes.

Question:

(1) how to call a method on the Module of the Application of a class of ViewObjectImpl?
```
  public void setPrice(Number value)
  {
    setAttributeInternal(PRICE, value);
    
    DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
    BindingContext bctx = bindings.getBindingContext();
    DCDataControl control = bctx.findDataControl("AppModuleDataControl");
    ApplicationModule am = (ApplicationModule ) control.getDataProvider();
    //uh now what??
    // am.getProperty("method call(getTipsNum())") ?
  }
```
(2) when I set an attribute on a view through the AppModuleImpl object, I'll make an infinite loop in this way? that is the AppModuleImpl calls the ViewRowImpl class on a setAttribue (< name >, < value >)?

Thank you guys.
It's an interesting problem, I'll take a stab to solve here.

First let's see I understand the data model:

(a) there is a table called BOM with a self referencing FK creating a hierarchy of data
(b) each record BOM is usually a child to another record BOM, so using your example, a van is composed of frames and tires - Let's say that this amounts to 3 records in the Schedule table.
(c) check parent, truck, is the root of the hierarchy, and so the FK relationship sucks.
(d) the price of a truck consists of its children. So if the frame costs $1,000 and tires $500, the pickup truck costs total $1,500.
(e) a change in the price of any folder BOM, upwards or downwards must be propagated to its parent folder BOM. As an example, if the tires up to $600, the pickup truck is now $1600 ($1000 frame + tires $600).

Does this sound right?

Well, that I understand the data model, here's what I'd do build in what concerns objects ADF BC:

(1) an entity BOM (EO) object - let's call this Bom
(2) a BOM BOM EO association (representing the self referencing FK)-Let's call it BomBomFkAssoc
(3) an object to view BOM (VO) based on the EO - let's call it BomView
(4) BOM VO view link BOM VO based on EO of #2 association - call BomBomFkLink

Next, we create the Java constructs:

(5) #1 ensures that the EntityImpl has been created
(6) #4 guarantees for the EO association that it generates the required Java accessors

Now the additional code:

(7) for the EntityImpl # 5, in the field of setter setPrice() something like the following:
```
public Number setPrice(Number value) {
  Number diffPrice = value.minus(getPrice()); 

  setAttributeInternal(PRICE, value);

  BomImpl parentBom = getBom(); // from step #6, the EntityImpl should have an accessor method to it's parent BomImpl record
  Number parentDiffPrice = parentBom.getPrice().add(diffPrice);
  parentBom.setPrice(parentDiffPrice);
}
```
From a point of view JSF, now when I change a specific record of the Nomenclature in an edit form, a change for the price of registration for the Bill to submit time will automatically propagated to the top of the hierarchy of the BOM because the method setPrice() of the current OS of BOM will walk to the top of the hierarchy of the BOM to the parent following the call it is setPrice() method , which will be then walk to the next BOM record and so forth. At the time all BOM records with changes should be committed to the database.

You don't need to test this in JSF, but simply the browser component of company on the Application template project Module.

.... Of course... If I misunderstood your data model, it will be of no help whatsoever.

How can I avoid losing image changes I've already done when changing the name of a folder?

How can I avoid losing image changes I've already done when changing the name of a folder? Whenever I have change a folder name (after having published images), Lightroom "updates" the images in this folder and any changes I've made have disappeared!

Thanks for the update.

This isn't the correct workflow.

When you rename a folder outside of Lightroom, it causes the link between this issue and Lightroom to be broken and images will be missed in the Lightroom Catalog

and if you re-import them same images after that, it will import the original images and not the changes

Lightroom does not store the original images it contains. It works on the previews and the changes you make are stored only in Lightroom.

So, you have to rename or move this folder in Lightroom instead of doing outside so that you do not lose your changes.

To rename a folder, select the folder name in the library module > right click / Control click and select Rename folder.

How to add italics or bold words when changing the webtext in catalyst

How to call this method?

I wrote this method earlier, but I do not remember how to call it. Can someone help me?

        ConnectionFactory connFact = new ConnectionFactory();
        ConnectionDescriptor connDesc;
        connDesc = connFact.getConnection(_url);
        if (connDesc != null) {
            HttpConnection httpConn;
            httpConn = (HttpConnection)connDesc.getConnection();
            try {
                final int iResponseCode = httpConn.getResponseCode();
                UiApplication.getUiApplication().invokeLater(new Runnable()
                {
                public void run() {
                    //Dialog.alert("Response code: " + Integer.toString(iResponseCode));
                }
                });
            } catch (IOException e) {
                Dialog.alert("Caught IOException: " + e.getMessage());
            }
        }
    }
}

You can simply call News PostReview.Submit (url). But why the class extends Thread If you aren't actually create or who runs an instance of thread?

Error when calling a method AM of Bean managed

Hi friends,
JDev's Studio Edition Version 11.1.2.4.0
I have a page (HomePG) that has a read-only table. Select a field in the table and you enter a value for the inputText and then clicking on a button, the selected employee's salary should be replaced by the value entered in the inputText field.
I am trying to call a method of the managed bean AM and I get an error while doing this. I created a link to the method in the page where the call is made.
Here is the code of the AOS
' Public Sub hikeSelectedRow (Key key, BigDecimal val) {}
ViewObjectImpl emp = getEMPVO1();
RowSetIterator empVO = emp.createRowSetIterator ("Test");
System.out.println ("in selected Update");
System.out.println ("in selected, Update key:" + key);
Row [] selectedEmpArr;
selectedEmpArr = empVO.findByKey (key, 1); -> Error comes here
System.out.println ("in selected, Update key:" + key.toString ());
EMPVORowImpl selectedEmp = (EMPVORowImpl) selectedEmpArr [0];
selectedEmp.setSal (selectedEmp.getSal () .add (val));
System.out.println ("added, made Bravo");
getTransaction () .commit ();
}
The line is selected in the Managed bean and is also selected. However during appraisal findByKey get the performance I get the below error. Can someone please.
The error I get is

I suppose this relates a strange string?

How to call a method abstract in Java

Hi all
I am new to Java, and have been learning. I have a question here. I came across the following Java class and trying to understand but got confused how he is able to call an abstract method. Here's the code I'm referring to:
package sampleapps.gui;
Javax.swing import. *;
import java.awt.*. *;
public class InnerClassAnimationExample {}
int x = 70, y = 70;
Public Shared Sub main (String [] args) {}
InnerClassAnimationExample innerClassAnimationExample = new InnerClassAnimationExample();
innerClassAnimationExample.go ();
}
public void getCurrentCard {}
JFrame frame = new JFrame();
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
NewMyDrawPanel drawPanel = new NewMyDrawPanel();
frame.getContentPane () .add (drawPanel);
frame.setSize (300, 300);
frame.setVisible (true);
for (int i = 0; i < 500; i ++) {}
x ++ ;
y ++ ;
drawPanel.repaint ();
try {}
Thread.Sleep (50);
} catch (Exception e) {}
e.printStackTrace ();
}
}
}
class NewMyDrawPanel extends JPanel {
{} public void paintComponent (Graphics g)
Graphics2D g2d = (Graphics2D) g;
Red int = (int) (Math. random() * 255);
int green = (int) (Math.Random () * 255);
Blue int = (int) (Math. random() * 255);
Color startColor = new color (red, green, blue);
Red = (int) (Math. random () * 255);
Green = (int) (Math.Random () * 255);
Blue = (int) (Math.Random () * 255);
Color endColor = new color (red, green, blue);
GradientPaint gradient = new GradientPaint (7070, startColor, 150 150, endColor); We can also use colors straight as Color.RED, Color.BLUE
GradientPaint gradient = new GradientPaint (7070, startColor, 150 150, endColor);
g2d.setColor (Color.White);
g2d.fillRect (0, 0, this.getWidth (), this.getHeight ());
g2d.setPaint (gradient);
g2d.fillOval (x, y, 40, 40);
}
}
}
For example, in the code above, there are an internal NewMyDrawPanel class that has a method paintComponent (Graphics g). I've highlighted the 2 lines of code above.
Line 1 : Graphics2D g2d = (Graphics2D) g;
Line 2 : g2d.fillOval(x,y,40,40);

I understand that we are casting type reference to Graphics2D g reference g2d and we call the method fillOval() on g2d. I do not see a method of fillOval() in the Graphics2D class but it's there in the Graphics class and Filloval()) method is an abstract method.
So my question is:
1. If we are not able to instantiate an abstract class (Graphics2D Graphics classes) and how are we able to access the abstract method fillOval()
2. Secondly, given that the fillOval() method is an abstract method, it has no implementation for the method. However, when I call the method fillOval() on Graphics2D reference, I was able to draw and fill in an oval of the specified coordinates. Then, where the actual implementation code would be?
Could you please, somebody explain how this happened? Pls help.
Thanks in advance.

The point of having the Graphics class declaring fillOval() summary, is that we can have confidence that all the graph goes instantiable subclass is an implementation of this method. You as the user of this unknown implementer of graphics have no need of care including probably several classes in this legacy hirarchie did the implementation. You just trust in the fact that it must be there, because the java compiler takes care of this.
