• Want to add Action Listener programmatically on a button created Progammatically.

  Scenario is,

  I want to add the listener of pressing a button I've manually created and added to the page over time.

  Hey Zaid,

  Try the following code.

  1. create the inner class on your managed bean.

  private class MyListener implements ActionListener {

  write your action listener code here...

  System.out.println ("invoked");

  }

  }

  2. then add actionListener class to your button.

• JavaFX binding throws illegal state Exception: not on the thread of Application FX

  Hi all

  I am updating a label of a task using bindings.

  However, when I 'Bind' the label text property with a property of the task, Illegal state exception string is thrown. Saying: this is not not on the thread of JavaFX.

  The Exception occurs whenever I try to set the property of the task of the Interior string.

  Please do not suggest to use the platform. RunLater(). I want to do this through links as the values I am trying to display in the label (later on) could change too frequently, and I don't want to flood the queue of the thread of the user interface with executable objects.

  Please let me know what I'm doing wrong and what I need to change to make it work properly with links. (I'm new to links and concurrency JavaFx API)

  Here is my Code.

  public class MyTask extends Task<String>{
  
      MyTask(){
         System.out.println("Task Constructor on Thread "+Thread.currentThread().getName());
  
  
      }
      private StringProperty myStringProperty = new SimpleStringProperty(){

  And it is the output with links on:

  If myStringProperty is bound to the textProperty of etiquette, you can only change it on the Thread of the JavaFX Application. The reason is that change its value will result in a change of the label, and changes of live parts of the graphic scene cannot be performed on the Thread of the JavaFX Application.

  Task and Service classes expose a messageProperty you could use here. The Task class has a updateMessage (...) method that changes the value of the message on the Thread of the JavaFX Application property. It also merges calls in order to prevent the flooding of this thread. If you could do the following in your MyTask.call () method:

  updateMessage(""+counter);
  

  and then in your controller just do

  label.textProperty().bind(myTestService.messageProperty());
  

  If you don't want to use the messageProperty for some reason any (for example you are already using it for something else, or you want to make something similar to a property that is not a string), you must merge the updates yourself. What follows is based on the source code of the task:

  public class MyTask extends Task {
  
       // add in the following:
      private final AtomicReference fileString = new AtomicReference<>();
  
      private void updateFileString(String text) {
          if (Platform.isFxApplicationThread()) {
              setFileString(text);
          } else {
              if (fileString.getAndSet(text) == null) {
                  Platform.runLater(new Runnable() {
                      @Override
                      public void run() {
                          final String text = fileString.getAndSet(null);
                          MyTask.this.setFileString(text);
                      }
                  });
              }
          }
      }
  
     // Now just call updateFileString(...) from your call() method
  }
  

• How to bind the ACTIONS/help for a newly created button?

  I created a button to open a window pop up and display the same information if you click ACTIONS and then to HELP on a report/interactive form however, I find myself with a white pop-up screen
  
  I under the Action when the button is clicked
  
  action = URL redirection
  validation = YES
  
  URL =
  
  JavaScript:popupURL('wwv_flow_utilities.show_ir_help?p_app_id=101&p_worksheet_id=3&p_lang=en');
  
  any ideas?
  
  Thanks in advance for the help.

  Why not make your button click on fetch the IR Help menu link on-the-fly and use it

  Change your action buttons to redirect URLS

  JavaScript: Window.Location.href is $('_#apexir_ACTIONSMENU_a.dhtmlSubMenuN[title="Help"]').attr ('href');.

  Or even the following would

  JavaScript:popupURL ('wwv_flow_utilities.show_ir_help? p_app_id ='+ $v ('pFlowId') ' + ' & p_worksheet_id = ' + $("div_#apexir_DATA_PANEL_table.apexir_WORKSHEET_DATA').attr ('id'))

  It also has the advantage that there is no demand or worksheet_id hardcode in the URL.

• How given the action to a dynamic button programmatically?

  Hello

  I use JDeveloper 11.1.1.6

  I am trying to assign the action to a button that is created programmatically, using the following code:

    functionButton.setActionExpression(GlobalUtils.createActionMethodExpression("#{CollectorBean.invokeFunctionCall}"));
  

      public static MethodExpression createActionMethodExpression(String actionMethodExpression){
          FacesContext fctx = FacesContext.getCurrentInstance();
          ELContext elctx = fctx.getELContext();
          Application app = fctx.getApplication();

          methodExpr = exprFactory.createMethodExpression( elctx,actionMethodExpression ,null, new Class[]{});
          return methodExpr;
      }
  

  But it gives an error:

• Alternative to the model of David Giammona ADF area popup?

  Hi all
  
  y at - it anyway more simple/pattern, to include fragment (so, no full page) based bounded workflow inside af: light popup, but to do the same (cleaning of good task flow etc...)?
  
  In our current application, so we have a lot of these use cases, the implementation of this model in each case will be a time wasting.
  We need something less complicated.
  
  Any help?

  In I think JDev 11.1.3 a new af:popup property has been introduced: chiildCreation which can be set to 'deferred '. This property with the property deferred workflow link prevents loading of taskflows displayed in a box inside a pop-up window on the initial page load.

  It is an alternative to the technique of David so that's why the bosses is discouraged.

  The difference however is that, once the popup is open the taskflow is responsible and will remain loaded, consumes resources.
  If you want to release these resources again when you close the pop-up window, you can use the activation on the taskflow binding property. Bind this property to a Boolean property in a managed bean and the value of this property to true when the pop-up window is opened and set it to false when the popup window is closed.

• reset the action using a few imagelink

  Hi experts,
  
  11.1.1.5.0 - adbc - oracle db10g jdev
  
  Hi I know not af:reset button is to reset the fields.
  
  but trying to do commandImageLink link.
  
  Why go commandImageLink means. image link has some pictures. every time the link. I have to reset the fields.
  
  I can't do this. How can I do?

  <af:commandImageLink styleClass="OraBITooltipText"
                                         shortDesc="Clear"
                                         binding="#{backingBeanScope.glm0020.cil18}"
                                         id="cil18" icon="/icons/clear.png">
                      
                    </af:commandImageLink>

  ERP,

  something is entered in the field of af: table and I use commandimagelink to clear the entrance to the fields. It does not work properly. (Documents restored enterily)

  So what you see is that the new created line is removed, correct? Well, if that's your problem (I'm not quite sure that you mentioned on page 1 of this thread) then you can have an action listener defined (link order the value partialSubmit = true) who has access to the current row in the table, pass the attributes of this line and set them to null. However, for this you need to PPR table (as if not a single row refresh is not displayed).

• Access the corresponding line via detailStamp triggered the action

  Hello
  
  I am clearly not understanding something :/ I have a problem I'll demo with a small application here. I have a 'DeptView"(which is the SQL query mode, select deptid, deptname of Department in the HR schema) on which I based a simple af:table. It works very well, listing the data without problem.
  
  In the 'detailStamp' side, I have form fields based on the 'row' of the af var: table. This works fine as well. I use the DeptView as a DTO object, and in a backingbean action, I want to know what line the timbre of detail with the action button belongs to. Here is the demo app, showing the three different methods I've tried. The problem is the code I found returns the selectedRow, not the line containing the invocation of the action contained detailStamp.
  
  Here is an example of output about what is happening when I develop four lines, select the line 'marketing', then click "Who Dept?" in each detailStamp.

  Support action of bean:

          FacesCtrlHierNodeBinding data = 
                  (FacesCtrlHierNodeBinding)depTableBinding.getSelectedRowData();
          resultFromTable.setValue(data.get("DepartmentName"));
          
          // ---------------------------------------
          // VO
          DCBindingContainer bindings = 
                  (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();  
          DCControlBinding cb = (DCControlBinding)bindings.get("DeptView1");
          Row currentRow = cb.getViewObject().getCurrentRow();        
          resultFromVO.setValue(currentRow.getAttribute("DepartmentName"));
          
          // ---------------------------------------
          // Iter
          DCIteratorBinding iterBind = bindings.findIteratorBinding("DeptView1Iterator");
          currentRow = iterBind.getCurrentRow();
          resultFromIter.setValue(currentRow.getAttribute("DepartmentName"));
          
          // mark textfields for refresh
          RequestContext rc = RequestContext.getCurrentInstance();
          rc.addPartialTarget(resultFromTable);
          rc.addPartialTarget(resultFromVO);
          rc.addPartialTarget(resultFromIter);
                  
          return "blah"; // doesn't matter        
      }

  I guess that a solution would be allows only a single detailStamp open at a time, and get a rowDisclosureEvent to the other door detailStamps Manager and make the current line active (someone has me code is 11g to do this easy?). I feel however that I am just misunderstanding something basic.
  
  Thanks in advance

  Hi Barry,.

  What you see is expected, extend a row does not define the current line as the extended line. If you want to get the current line (where you have the button) at the click of a button, try the approach below:

     //Pass the row to the bean property on click of a button using setActionListener tag
            
                
                                  
              
                 
  
      //Inside Bean
      private FacesCtrlHierNodeBinding currentNode;
  
      public void setCurrentNode(FacesCtrlHierNodeBinding currentNode) {
          this.currentNode= currentNode;
      }
  
      public FacesCtrlHierNodeBinding getCurrentNode() {
          return currentNode;
      }
  
      public void printCurrentRow(){
          DCBindingContainer bindings =
                         (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
          DCIteratorBinding iterBind = bindings.findIteratorBinding("DeptView1Iterator");
          Row currentRow = currentNode.getRow();
  
          //Write your code here
  
      }

• Impossible to define the action of opening image/jpeg in Firefox

  I want to just open and display a jpg in a firefox tab, but instantly, link it asks me if I want to save or open by another application. Fine. I go into Options - handling jpg action change requests. There are 2 types of jpeg, one is "JPEG Image (image/jpeg) and the other"JPEG Image (text/html). I can change the action "text/html" to serve the action by default for Firefox, but for "image/jpeg", no matter how many times I tried, it just does not allow me to choose Firefox but any other actions or requests. Precisely, I choose Firefox in the 'Select Helper Application', but after I clicked 'OK', she returned to the old stock. I tried restarting Firefox and tried again, but not good at all. It frustrates me so bad.

  Are you sure that these images are to be sent with the right kind of MIME for images and not with the generic MIME type that makes Firefox view the 'Open with' dialog box?

  Watch Me Do is designed to replay the same click of mouse and keyboard events to the same speed.  Think of driving your car to work and record each turn and stop.  Then play each round and down at the same speed.  What to do if while reading the traffic moves a little faster or a little slower?  If you drive the same route to work, you could get a red light at an intersection that you had a green light to yesterday.  "Watch Me" does not know how to deviate from these changes, so he'll just to stop and report an error.  If iTunes launches slower or an event during playback takes longer to achieve because of different background running processes, it will have the same effect.

  Allowing automatic downloads in iTunes and help Automator to activate your device network at a specific time might be a better solution.

• Error-124102 when the action on the download

  I use action on download put some files on target RT. When I use the reference of the action on the download, all results of action by error-124102. Refrence seems to be valid, when I cast to I16, the value is 1.

  But if I open the session manually (with user IP name and admin), using session open, everything works correctly, I use the same paths etc. The session opened manually reference value is 2.

  Someone at - it work?

  SP1 VS 2015

  It is resolved already, I was using prefix /files/ with relative paths. Without this prefix, all functions working properly.
