NullPointerException fx: include

Hi guys,.

I'm going crazy with this error. I have worked on this for 2 days and I can't find a solution.

When I do a fx: include in my fxml file, I got this error:


Caused by: java.lang.NullPointerException
  at javafx.fxml.FXMLLoader.equals(FXMLLoader.java:1856)
  at javafx.fxml.FXMLLoader.isCyclic(FXMLLoader.java:1868)
  at javafx.fxml.FXMLLoader.access$2100(FXMLLoader.java:71)
  at javafx.fxml.FXMLLoader$IncludeElement.constructValue(FXMLLoader.java:941)
  at javafx.fxml.FXMLLoader$ValueElement.processStartElement(FXMLLoader.java:570)
  at javafx.fxml.FXMLLoader.processStartElement(FXMLLoader.java:2356)
  at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2172)

Here's my root file:


<fx:root type="javafx.scene.layout.AnchorPane" fx:id="scrollPane" id="scrollStocksList"
  xmlns:fx="http://javafx.com/fxml"
  fx:controller="net.StocksListRunningController">
   <fx:include fx:id="tableListStock"
  source="/fxml/stocksList.fxml" />
</fx:root>

And my include file:

<Button layoutX="15.0" translateY="10" mnemonicParsing="false" text="Fermer"
        onAction="#close"/>

If I remove my fx: include in my root file, all work fine.

I can't debbug because the source is not provided.

I try an alternative to my tag fx: include:

<fx:include fx:id="tableListStock" charset="UTF-8" resources="/bundles/messages"
  source="/fxml/stocksList.fxml"  />

And I get this error because the loader is null:

Caused by: java.lang.NullPointerException
  at java.util.ResourceBundle.getBundle(ResourceBundle.java:1026)
  at javafx.fxml.FXMLLoader$IncludeElement.processAttribute(FXMLLoader.java:902)
  at javafx.fxml.FXMLLoader$Element.processStartElement(FXMLLoader.java:185)
  at javafx.fxml.FXMLLoader$ValueElement.processStartElement(FXMLLoader.java:568)
  at javafx.fxml.FXMLLoader.processStartElement(FXMLLoader.java:2356)
  at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2172)

I don't understand why the loader is null.

I use the latest version of java fx provided by jdk 7.0.51.

What is bad in my include file (or other)?

Thanks for your help.

Hello!

I had the same problem today and followed a location missing in my case FXMLLoader.

It defines explicitly as fxmlLoader.setLocation (Main.class.getResource ("dialog.fxml")); before you make a call to fxmlLoader.load did the trick

for me.

I hope this helps.

Best regards

Christian

  • Trying to update vCAC Blueprint entity, gets "java.lang.NullPointerException".

    Hello

    I am trying to create a fairly complex workflow in vRealize Orchestrator.

    The purpose of this workflow is to clone a vRealize current/previous deployment MultiMachine Automation and mark the new clones as models and then update a plan Director multi-machine 'Ad hoc' vRA with these models new vCenter.

    Right now, I figured out how to map prints blueprint only computer individual Ad hoc, to clone new models of vCenter.

    This is done in the "VirtualMachineTemplateProperties" of each single computer model part.

    Thanks to a code borrowed Christiaan Roeleveld createiaasblueprintfortemplate package

    But because the components of the original deployment MultiMachine could were converted to the CPU and memory, I need to update the entity for SingleMachine component plans.

    I have one tries to use the workflow by default to "Update an entity of the vCAC model" for this.

    The code below is just hard code examples.

    I create a set of properties:

    theBlueprintEntityProperties =
    {
      CPUCount : "2",
      MemoryGB : "4096",
      DiskSize0GB : "20"
    };
    

    I then try to run the workflow 'Update an entity of the vCAC model' (inside my workflow of wrapper of cause), with the following entries:

    entity = theBlueprintEntity
    inputProperties = theBlueprintEntityProperties
    links = null
    headers = null
    

    But I get just "java.lang.NullPointerException".

    Correctly, this means that I need to include links or headers.

    I tried with a few links, again using package Christiaan Roeleveld createiaasblueprintfortemplate code

    But even if I include the following links:

    var links = {
      "InterfaceType": [ interfaceType ] // The vCAC Entity for the vSphere interface,
      "HostReservationPolicy": [ reservationPolicy ] // The vCAC Entity for my Reservation Policy,
      "ProvisioningGroup": [ provisioningGroup ] // The vCAC Entity for my Procisioning Group / Business Group,
      "WorkflowInfo": [ cloneWorkflow ] // The vCAC Entity for the Clone Workflow,
      "GlobalProfiles": buildProfiles // Array of build profiles, in this case just a array of one build profile,
    }
    

    I still just takes "java.lang.NullPointerException".

    Someone has a few entries on how to upgrade the vCAC entity for a master plan, with regard to the CPU, memory or disk?

    Environmental information:

    vRealize Orchestrator = 6.0.3 Build 3000581

    vCAC/vRA Pluging in vRO = 6.2.2

    vRealize Automation = 6.2.2 Build 2754020

    I found the problem.

    The problem is that the properties in the vRO inventory, for example 'VirtualMachineTemplateDescription' has an envelope has changed compared to the vRA SQL database.

    In the vRO inventory, it is listed as virtualMachineTemplateDescription ("v" in lowercase)

    But in the vRA, database SQL, it is listed as VirtualMachineTemplateDescription (capital ' V')

    And when properties are not what is in the database, the answer back is:

    java.lang.NullPointerException
    

    Here's the corrected code that updates the VirtualMachineTemplateDescription, the CPUCount and the MemoryMB of an entity of Blueprint.

    var entity = theBlueprint.getEntity();
    
    var properties =
    {
      VirtualMachineTemplateDescription : "Testing Description",
      CPUCount : 8,
      MemoryMB : 18432
    };
    
    var hostId = entity.hostId;
    var modelName = entity.modelName;
    var setName = entity.entitySetName;
    var keyString = entity.keyString;
    
    vCACEntityManager.updateModelEntityBySerializedKey(hostId, modelName, setName, keyString, properties, null, null);
    
  • FXML: &lt; fx: include / &gt; with the attribute of resources. How does it work?

    Hello

    I am trying to understand FXML and I struggle with the help of ResourceBundles / internationalization.

    I did a common component, which relies on its own resources file, let's say the package 'fxml', I have:

    Control.fxml

    Control.Properties

    Control_de. Properties

    Another FXML includes this one:

    <? import javafx.scene. *? >

    <? import javafx.scene.control. *? >

    <? import javafx.scene.layout. *? >

    < fx:root type = "javafx.scene.layout.VBox" xmlns:fx =" " http://JavaFX.com/fxml ">

    < fx:id TextField = "textField" / >

    "< fx: include source="/fxml/Control.fxml ' resources = "fxml. Control"/ >

    < / fx:root >

    If I load only through:

    LoginView parent = FXMLLoader.load(getClass().getResource("/fxml/Login.fxml"), ResourceBundle.getBundle ("fxml. User name'));

    I get the following exception:

    What's not here? fxml. Control.Properties there permanently.

    If I remove the < fx: include / > element, everything works fine.

    Is it possible to include resources directly in a FXML, so that I don't have to specify them again in each include?

    I'm guessing that this is the problem that you run in:

    How is used with fx i18n resources: include?

  • How is used with fx i18n resources: include?

    I can't seem to get bundles of resources working with fx: include.  This old post suggests it should work, but I'm running into two different errors.  I downloaded a very simple example here:

    https://DL.dropboxusercontent.com/u/8788282/sample-app.zip

    The example has everything set up the way I expect to work.  When I open "MainView.fxml" with SceneBuilder (7 bundled JRE), I get a MissingResourceException.  When I try to run "SampleApp" using JDK8-b111 I get a NullPointerException.  In the second case, it seems that fxmlloader might be passing a null to ResourceBundle ClassLoader.

    Does anyone know how to use beams of resource with nested views?  The Introduction of to FXML. JavaFX 2.2 docs silence resources fx: includes, but does not explain how it is supposed to work.

    A possible workaround is to make sure the ResourceBundle you go to your main FXMLLoader is not loaded by the system class loader. I think that the best way to proceed is to wrap the resource group, you get in the usual way in a trivial wrapper implementation. Something like this:

    import java.io.IOException;
    import java.util.Enumeration;
    import java.util.Locale;
    import java.util.ResourceBundle;
    import java.util.Set;

    public class ResourcesTest extends Application {
    
     @Override
      public void start(Stage primaryStage) throws IOException {
           ResourceBundle resources = new ResourceBundleWrapper(ResourceBundle.getBundle("resources.Resources"));
           System.out.println(this.getClass().getClassLoader());
           System.out.println(resources.getClass().getClassLoader());
           FXMLLoader loader = new FXMLLoader(getClass().getResource("ResourcesTest.fxml"), resources);
           Parent root = (Parent) loader.load();
           Scene scene = new Scene(root, 300, 120);
           primaryStage.setScene(scene);
           primaryStage.show();
      }
    
      public static void main(String[] args) {
           launch(args);
      }
    
     // this class effectively does nothing, but it will be loaded by the
     // application class loader
     // instead of the system class loader.
      private static class ResourceBundleWrapper extends ResourceBundle {
    
           private final ResourceBundle bundle;
    
           ResourceBundleWrapper(ResourceBundle bundle) {
                this.bundle = bundle;
           }
    
           @Override
           protected Object handleGetObject(String key) {
                return bundle.getObject(key);
           }
    
           @Override
           public Enumeration getKeys() {
                return bundle.getKeys();
           }
    
           @Override
           public boolean containsKey(String key) {
                return bundle.containsKey(key);
           }
    
           @Override
           public Locale getLocale() {
                return bundle.getLocale();
           }
    
           @Override
           public Set keySet() {
                return bundle.keySet();
           }
    
           }
    }
    

    The simplest workarounds is may be possible, but I don't see one right now...

  • NullPointerException on &lt; jbo:DataHandler / &gt; tag

    I'm working on the maintenance of older web applications Java/Houston, originally written in jDeveloper 9.

    In Oracle Enterprise Manager, I can activate the debugging under JSP properties > run settings.

    Line 231 in the JSP file is:

    The error only occurs on my JSP pages that use the DataHandler tag.

    My problem is to understand what is causing the NullPointerException, and why this happens only on the
    physical server. Even more curious, the application seems to work despite the error message (I can visualize the data of the)
    database, State is preserved in different Web pages, and I can even modify the database)...

    It is a possibility, but we can not really help you here. This old technology and not used by many users today. If you have a support contract, you should open a SR with support and see if they can help out you.

    Moreover, you never said which exact version of 10g you are migrating to. Maybe you should try one another and see if the error fixed (if that's a mistake).

    So this means JavaFX is made only for Netbeans and does not run in other IDEs?

    No, the other IDEs can build and run JavaFX applications.
    For Oracle JavaFX samples, it is just easier to use NetBeans because they have already defined NetBeans projects.

    I created a project idea which includes the NetBeans project, added sources has the JavaFX runtime library for the project Idea (C:\Program Files\Oracle\JavaFX 2.1 Runtime\lib\jfxrt.jar), adjusted settings-online settings idea | Compiler | Patrons of resources to add;? *.fxml, you press Run and, even once, the sample ran without problem.

    Idea is a bit limited by default when copying of resources, for example, you must add explicit reasons to copy things like css and javascript output directories for files.

    Without the model copy of resource fxml when developing applications based in the idea fxml, JavaFX 2.1 will not be able to find the fxml file because it is not copied during the compilation of the project output directory and JavaFX 2.1 raise an error when it runs:
    java.lang.IllegalStateException: location is not defined
    The error message can be a bit nicer and mention the path that cannot be found, but it makes sense.

  • NullPointerExceptions endless in Flash Builder 4.5

    I have been using Flash Builder 4.5 with the kit Flex 3 SDK. 5 b on Mac OS X 10.8.2 for a few months. It was not an experience perfect - the software has a few bugs, but in general he worked until recently.

    Our application includes two Flash Builder 'projects', which refers to the other. Whenever clone us the repository, it is necessary to update the file .project of the primary project to include the new path of the secondary project.

    The last thing I did before all broken did was move the folder containing the project to a new location. As expected, when I open Flash Builder, it complained that it couldn't find my project files, and they were all marked as inaccessible in the "Package Explorer" view. I did not remove inaccessible project in my workspace, but I tried to re - import the main project of his new location. It was the first time I saw a dialog box that has haunted me since:

    'Building workspace' has encountered a problem. Errors occurred during the build. Details: Errors running 'Flex' on project 'configurator'. java.lang.NullPointerException

    The view of 'Problems' told me to return in the errorlog...

    Errors (2 items): an internal build error has occurred. See the error log for more information.

    .. but the error log was empty!

    The "Package Explorer" view has not changed (the new draft has not been listed) so I decided to just try the import again. When I chose the directory of the project, Flash Builder said that I couldn't import it because the project was already in the workspace. "But the Explorer Package says it's not... maybe he'll try again if I restart Flash Builder" I thought. I have bad thought. When I rebooted, it is what I saw:

    Could not create the view: an unexpected exception was thrown.

Deleting all files from the project did not help either. I was unable to set the workspace, and the only way I could continue to use Flash Builder has been creating a new workspace.

    Since then, I tried a lot of different things:

    • Reinstalled Flash Builder 4.5.
    • Reinstalled Flex SDK 3. 5b.
    • Excerpt from a six - month old version of the project.
    • Flash Builder 4.6 upgrade.
    • Created a new user profile on my computer.
    • Tried to remove some trace could have broken things:
      1. Instruments to monitor the process of Flash Builder affects all files.
      2. Uninstalled Flash Builder.
      3. Used find to locate include files builder or eclipse in their name.
      4. Delete all the files found in (1) or (3) who seemed possibly related to Flash Builder.
      5. Reinstalled Flash Builder.
    • Installed Flash Builder 4.5 on another Mac running Mac OS X 10.6.8.
    • Installed Flash Builder 4.5 in a Windows 7 VM.

    None has made any difference. It seems impossible.

    Other members of my team have worked on this project for a few years without running into this particular issue, yet now project versions from before that I started appear to be broken, and even with the help of new installations of Flash Builder on entirely different systems also violates.

    I don't know what is happening. It seems I must have done something else and forgot about it, because the current situation makes no sense. Someone has encountered this problem before? Do you have an idea what could be causing it, or that I could do about it?

    We finally found a solution. It's rather disappointing.

    Ignore any errors.

    Import your project files and activate the correct SDK version in the order you want. If you find yourself with a messed up view "Project Explorer", with just the close and reopen it or restart Flash Builder.

    Once the display of "Project Explorer" is available, select your primary project and run it. It should work!

    Anyone know what is the problem and how to fix it?

    I downloaded the ALBUM here:

    http://subzero.EU/WP-content/uploads/2012/10/EU.subzero.SZJpegEncoder.ane_.zip

    It is a known problem in AIR3.4.

    Here are two solutions for you-

    1. use the latest version of laboratories AIR3.5 (http://labs.adobe.com/downloads/air3-5.html)

    2. or, if you want it to work with your current configuration, as a solution, please also use Add a finalizer to your DONKEY function and declare in your extension.xml. The finalizer can do nothing, but simply return.

  • NullPointerException error in canvas

    Hey all,.
    I have a main MXML application that contains a Web. I have another component MXML, called viewBestelling, I load in the root Web. Simply using: rootcanvas.addChild (viewBestelling). Which works very well. In this painting, (viewBestelling) some other components. There is only a viewstack that contains another painting, which contains 2 panels. Now, in one of those signs, I put a few tags.
    I have also some Actionsript in my component viewBestelling. One of my labels in one of the panels a id: klantnummer. When I then use for example:
    klantnummer. Text = "blah"; in my actionscript,.
    I get a NullpointerException pointing to this line of code. I don't really know why.
    I have another label on my main cloth in viewBestelling. I can change the text of it through actionscript that is no problem.
    Furthermore, I give the floor that it function initsialiseer (best_in) in my main application, there may be something wrong.
    I'll include the code so that maybe someone can find a response and, hopefully, a solution to my problem.

    Thanks in advance,

    Jordy

    You may need to set the property of ViewStack's creationPolicy to 'all', but if you have a lot of content in the ViewStack it could affect performance.
