• 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(){
          {
              System.out.println("Creating stringProperty on Thread "+Thread.currentThread().getName());
          }
      };
      private final void setFileString(String value) {
          System.out.println("Setting On Thread"+Thread.currentThread().getName());
          myStringProperty.set(value); }
      public final String getFileString() { return myStringProperty.get(); }
      public final StringProperty fileStringProperty() {
          System.out.println("Fetching property On Thread"+Thread.currentThread().getName());
          return myStringProperty; }
      
      @Override
      public String call() throws Exception{
          System.out.println("Task Called on thread "+Thread.currentThread().getName());
  
  
         for(int counter=0;counter<100;counter++){
             try{
             setFileString(""+counter);
             }catch(Exception e){
                 e.printStackTrace();
             }
             Thread.sleep(100);
             System.out.println("Counter "+counter);
         }
         return "COMPLETED";
      }
  }
  
  
  public class MyService extends Service<String> {
  
  
      MyTask myTask;
  
      public MyService(){

      }
  
      @Override
      public Task createTask(){
          System.out.println("Creating task on Thread "+Thread.currentThread().getName());
          return myTask;
      }
  
  }
  
  
  public class ServiceAndTaskExperiment extends Application {
      @Override
      public void start(Stage stage) throws Exception {
          Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
          Scene scene = new Scene(root);
          stage.setScene(scene);
          stage.show();
      }
      public static void main(String[] args) {
          launch(args);
      }
  }
  
  
  public class SampleController implements Initializable {
      @FXML
      private Label label;
  
      @FXML
      private void handleButtonAction(ActionEvent event) {
          System.out.println("You clicked me!");
          myTestService.start(); //This will throw out exceptions when the button is clicked again, it does not matter
      }
  
      MyService myTestService=new MyService();
      @Override
      public void initialize(URL url, ResourceBundle rb) {
          label.setText("Hello World!");
          //adding the below Line causes the exception
          label.textProperty().bind(myTestService.myTask.fileStringProperty()); //removing this line removes the exception, ofcourse the label wont update.
      } 
  }
  //sample.fxml

  <?import java.util.*?>

  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
  }
  

• simultaneity and javafx.beans.property

  I am building a MVC architecture and I would like to model runs independently of the view/controller, for the model works with the controller/view.
  
  the following example is a very simplified version on how I got it:
  
  controller:

  public class controller extends AnchorPane implements Initializable{
       private ObjectProperty<Model> m;
       @FXML Label aLabel;
       
       public controller() throws Exception{
            this.m = new SimpleObjectProperty<Model>(this, "Model", null);
            FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("../view/View.fxml"));
            fxmlLoader.setController(this);
            fxmlLoader.setRoot(this);
            fxmlLoader.load();
       }
       @Override public void initialize(URL arg0, ResourceBundle arg1){}
       public void setGame(Model m) throws Exception{
            this.m.set(m);
            aLabel.textProperty().bind(this.m.get().getIntProperty().asString());
       }
       public void start(){
            //Method1:
            m.get().start();
            //Method2:
            Task<Void> task = new Task<Void>() {
                 @Override public Void call() {
                      m.get().start();
                      return null;
                 }
            };
            new Thread(task).start();
            //Method3:
            m.get().start();     //Model extends Thread and public void start() to protected void run()
            //Method4:
            m.get().start();     //Model extends Task<Void> and
                           //public void start() to protected Void call() throws Exception
            //Method5:          //calling any of the before ones on the controller that calls this one
       }
  }

  model:

  public class Model extends Thread{
       IntegerProperty intProperty;
       
       public Model(){
            this.intProperty = new SimpleIntegerProperty(0);
       }
       public IntegerProperty getIntProperty(){
            return intProperty;
       }
       public void start(){
            while (true){
                 this.intProperty.set(this.intProperty.get()+1);
            }
       }
  }

  I tried one of those and the results are:
  -Method1: the display is blocked and cannot be seen anything (model seems to work since ongoing in the loop)
  -Method2: when arrives the first this.intProperty.set (this.intProperty.get () + 1); the task is frozen and stops
  -Method3: error running on this.intProperty.set (this.intProperty.get () + 1);
  -Remplacement4: same as Method3
  -Method5: as before those
  
  How can I make the computer works?

  There are a few things wrong here.

  First of all, if you want the model to use a wire, make sure that you know how to use the Thread class. There is a decent section on concurrency in the Java tutorial [url http://docs.oracle.com/javase/tutorial/essential/concurrency/index.html]. What you need here, it's that your model class to override the run(), not the start() method method. Call then the start() method, which will cause the run() method run on a separate execution thread. (You can do this in method 3, I didn't understand your comment)

  It's probably just an artifact of your simplified version, but your run() method should block at some point. Multiple threads can be run on the same processor, if your current implementation can hog this CPU, it is impossible for the FX Application thread to do its stuff. For the test, throw in a call to Thread.sleep (...), wrapped in a try/catch block for the InterruptedException. I guess the real application expects something from the server, so there would be some "natural" the thread to block in this case.

  Important rule for the user interface is that changes made to the interface should be made only on the FX Application thread. Assuming you have the implementation of your model correctly running on a background thread, you violate it with your binding. (The model defines its intProperty on the background thread, the link causes the text of the label to change on the same thread). So to solve this problem your controller should listen to property int of the model changes and schedule a call to aLabel.setText (...) on the FX using Platform.runLater (...) application thread. You want to make sure that you do not flood the Application FX thread with too many such calls. Depending on how often the int in the model property is get updated, you discussed techniques in {: identifier of the thread = 2507241}.

  The tasks of JavaFX API provides friendly mechanisms to remind the JavaFX Application thread; However it is not really applicable in this case. The task class encapsulates a one-time job and (optionally) return a value and then ends, which is not what you're doing here.

  Here is a complete example; He is not broke in separate FXML for display and a controller, etc., but you can see the structure and break it down according to your needs.

• getAttribute after invokeMethod in processRequest throws NullPointerExcepti

  Hello:
  I appreciate your time to help me with this problem. I'm puzzled as to why this error is thrown. Pointers or ideas will be certainly useful. Please, share your ideas.
  =========
  Requirement:
  =========
  My basic page (custom OA Framework page) is called from another page with a parameter EstimateId. You use this parameter, I invoke a custom method "initHeaders" in processRequest executing the query on the view object wldssLabelEstimateHeadersVO. This query is performed on the base table that will return me a number of fields/columns based on the given primary key estimateId. As soon as I invoke the "initHeaders" method, I need a lot of the values returned by the query because only based on these values, I need to display the page properly.
  (For example) According to the type of estimate code, several elements/fields on the page are not appropriate. So, I have to hide those. When they are appropriate, I have to show them. Another area is "Die indicator. If it has a specific string value ("Die required'), I need restore a region called"dies. " And so on.
  
  ======
  Problem:
  ======
  I coded as follows in my page controller. After that I invoke the "initHeaders" method, if I do a findViewObject on the original Version and do a getAttribute, I should have the value in the EstimateTypeCode attribute. Fix? But he throws a NullPointerException.
  
  Here is the code:
  -------------------------------------------------------------------------------------------------- Code Begins -----------------------------------------------------------------------------------------------------------
  ' Public Sub processRequest (pageContext OAPageContext, OAWebBean webBean)
  {
  super.processRequest (pageContext, webBean);
  OAApplicationModule am = pageContext.getApplicationModule (webBean);
  String EstimateId = pageContext.getParameter ("EstimateId");
  If ((EstimateId! = null) & & (!("".)) Equals (EstimateId.Trim ()))
  {
  [Serializable] param1 = {EstimateId};
  am.invokeMethod ("initHeaders", param1);
  OAViewObject vo = (OAViewObject) am.findViewObject ("wldssLabelEstimateHeadersVO1");
  String estTypeCode = (String) vo.getCurrentRow () .getAttribute ("EstimateTypeCode"); -<-this line up the NullPointerException because vo is null
  [Serializable] param2 = {estTypeCode};
  am.invokeMethod ("initEstimateActions", param2);
  }
  -------------------------------------------------------------------------------------------------- Code Ends -----------------------------------------------------------------------------------------------------------
  
  I don't know what I'm missing. I checked for typos, correcting the names VO several times and am exhausted. Help please!
  Kind regards

  > mvn clean install javadoc:aggregate (this fails with NPE error)

  > mvn clean install javadoc:javadoc (this works)

  
  

  The question seems to be similar to Javadoc aggregation NullPointerException

  However, it is unclear what the resolution was.
  

  
  

  Any idea on how to solve this issue?

  Thank you in advance.

  The error was confused, I thought it was a problem with javadoc.

  We have updated the project dependency in the project, now it works.

  I'm not shure if I use .ai, .svg or other file formats and how to load that.
  
  I read on SVGGraph but failed to get the idea behind it
  (and think that's not for files)
  
  So please can someone tell me how single charge and show a graphic vector and formaterait which should take?
  
  Ah: A way to make this replaceable graph via CSS style would be nice too ;)
  
  Thank you

  This .fx file is probably the old 1.x JavaFX, which is no longer supported for JavaFX 2.x and to my knowledge there is also no converter for this.

• VAADIN and JavaFX

  I have already developed an application written in VAADIN (a library of java to create web user interfaces) to have a web interface for maintenance of an application. Everything works fine and development was very fast, but now I'm browsing the web interface by using the JavaFX WebView component and I suffer from a few problems. If I start to reload the URL after several tests the background of buttons does not load. I tried to change the cache from the Pier (used for browser VAADIN pages) to 0 without results.
  
  Once it fails the following are charged do not solve the problem. I can't reproduce this problem using firefox or chrome (which has the same engine as WebView I think). I also tried to reproduce the same situation using the demo "http://demo.vaadin.com/sampler#ButtonPush" but in this case, the problem is not in the same way, even if the background of the button may took several seconds in certain situations.
  
  Any idea? Any relevant configuration in the webEngine?

  I can't reproduce your problem (JavaFX 2.2b6 WinXPSp3).
  If you are not already the case, make sure you use JavaFX 2.1 + on a taken platform support (Windows or Mac).

  Here is an example of application.

  import javafx.application.Application;
  import javafx.scene.Scene;
  import javafx.scene.web.WebView;
  import javafx.stage.Stage;
  public class VaadinWebView extends Application {
    public static void main(String[] args) { launch(args); }
    @Override public void start(Stage primaryStage) {
      final WebView webView = new WebView();
      webView.getEngine().load("http://demo.vaadin.com/sampler#ButtonPush");
      primaryStage.setScene(new Scene(webView));
      primaryStage.show();
    }
  }
  

  Right-click on the Web view and choose reload to reload the page - I did it a lot, but he always worked (possibly) for me - it sometimes takes a while to load the graphics up, probably due to slow network connectivity to the site vaadin or inefficient javascript code in vaadin. I tried firefox, it was also slow to load images button too, but (maybe) a little faster than webview. I guess this all matches your description for http://demo.vaadin.com/sampler#ButtonPush

• NetBeans plugin 7 and JavaFX

  I'm the only person who can not get the JavaFX plugin to work with Netbeans 7?
  
  Downloaded 7 NB
  Installing Javafx 2.0 runtime
  Downloaded and installed the plugins nb javafx 2.0 according to the installation instructions.
  
  Then by restarting gives errors on the NB plugins - that must be disabled before you continue.
  
  Tried on both PC and had the same problem. Nb plugins seems to destroy the basic features in Netbeans (cannot create new projects)

  It worked for me:
  1 uninstall Netbeans 7.
  2 install Netbeans 7.
  3. start Netbeans and go to tools-> Plugins
  4. the new updates should appear. Install them. See patch info here http://wiki.netbeans.org/NetBeans7.0PatchesInfo
  5 install the JavaFx plugins

• Windows 7 - downloading patches and extensions keep throwing games

  I recently bought a laptop Asus with Windows 7 Home Premium x 64.  I was able to load and read of Civilization IV, Heroes of Might and magic and Elven Legacy, but games would launch is more after fixes or extensions have been uploaded.

  In particular, I bought the seat and Direct2Drive Elven Legacy magic expansions.  Once installed, the original game (who worked previously) and the or extensions would launch.  I just got the hourglass.  Restoration has allowed the original game function, but reinstall the downloads still caused a failure to launch.  Download of the official game patch on the working version of the original game also caused are unable to run the game.  The expansions it came out the last 60 days so should work fine on Windows 7.

  Heroes of Might Magic played fine on the facility, but when the official patch has been downloaded, the game would not launch either.  Check to Civ IV.

  Machine game with Trend Micro and disabling before and after the patch did not help.

  Try to run with administrator privileges and in compatibility mode gave the same result.  Asked me if I wanted to leave the program to make changes on the hard disk and click Yes.  Then, I'd get the hourglass and then nothing.

  I guess this is a feature of security, perhaps with IE, but can't seem to cross it and I got some games that I paid so that I can not install?

  Someone at - it gotten past this problem?

  Thank you

  lvwolverine,
  The games you listed show "Information coming soon" on the Windows 7 Compatibility Center.  This means that we are working with the software as to its compatibility.  It is perhaps that the expansion is not compatible, even though the basic game is.  You should check with game makers for the State to update their software for Windows 7.  You can also save the expansion, and then run the installation of the expansion in compatibility mode.   Mike - Engineer Support Microsoft Answers

  Hi philwhitesell,

  Follow these methods.

  Method 1: Uninstall and reinstall the Java application.

  Step 1: Start the computer in safe mode and check if the problem persists.

  Step 2: If the problem does not still in safe mode, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

  Note: After completing the steps in the clean boot troubleshooting, follow the section How to configure Windows to use a Normal startup state of the link to return the computer to a Normal startupmode.

  After the clean boot used to resolve the problem, you can follow these steps to configure Windows XP to start normally.

  (a) click Start, run.

  (b) type msconfigand click OK.

  (c) the System Configuration Utility dialog box appears.

  (d) click the general tab, click Normal startup - load all services and device drivers and then click OK.

  (e) when you are prompted, click restart to restart the computer.

  Method 3: Performs a search using the Microsoft safety scanner.
