  Hello

  When you set focuschangelistener to BitmapButtonField, it throws a NullPointerException.

  Someone knows why?

  Ex: myBitmapButtonField.setFocusListener (myFocusChangeListener);

  Additional information:
  

  • The project's POM and pom base have not been updated recently, in the past - he was able to generate javadoc:aggregate.
  • If I changed the switch of javadoc for javadoc:javadoc, the documents are generated successfully. This problem occurs if we use the javadoc:aggregate switch.

  > 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.

  Use case:

  During execution of the program, I can rollback in some cases. When the restore is executed the view lose its current line and returns to the default state (from the beginning). I store the last line someRow and try to return under the current name online in the view to help setCurrentRow method. But I always get a NullPointerException.

  It's been asked before, but there is no clear answer.

• JDK 8 and JavaFX TabPane throwing NullPointerException

  Hi all. I hope this is the right forum for this. I want to preface this question by declaring that the following code works perfectly fine in JDK 1.7. The goal here is to create a component with a tab at the end tab (with the value text '+') so that whenever this tab is selected, the program creates a new tab in the tab pane. This feature works fine. The problem is that when you close the new tab via the X, it goes to the tab 'add,' creates a new tab, then survey the following NullPointerException in some code JDK (and the app shows now TWO new tabs that correspond to the exact same object):

  Execution using the C:\Program Files\Java\jdk1.8.0\jre/bin/java java.lang.NullPointerException at com.sun.javafx.scene.control.skin.TabPaneSkin platform $TabHeaderSkin.access$ 302 (TabPaneSkin.java:1040) of C:\Users\XXXXXX\Documents\NetBeansProjects\TestJavaFx\dist\run2082574567\TestJavaFx.jar...

  I cut down the trouble code bare minimum to view the issue, and it's as follows:

  (Incase it do not paste correctly, see here: [Java] package testjavafx; import javafx.application.Application; import javafx.bea - Pastebin.com)

  package testjavafx;
  
  
  import javafx.application.Application;
  import javafx.beans.value.ChangeListener;
  import javafx.beans.value.ObservableValue;
  import javafx.scene.Scene;
  import javafx.scene.control.Tab;
  import javafx.scene.control.TabPane;
  import javafx.scene.control.TabPane.TabClosingPolicy;
  import javafx.scene.layout.StackPane;
  import javafx.stage.Stage;
  
  
  public class TestJavaFx extends Application {
  
  
      private TabPane tabPane;
      private Tab addTab;
      private Tab currentTab;
  
  
      @Override
      public void start(Stage primaryStage) {
  
  
          //Create the tab pane and the 'addTab' for adding new tabs.
          tabPane = new TabPane();
          tabPane.setTabClosingPolicy(TabClosingPolicy.SELECTED_TAB);
  
  
          addTab = new Tab("+");
          addTab.setClosable(false);
          tabPane.getTabs().add(addTab);
  
  
          //Add a listener to listen for changes to tab selection.
          tabPane.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Tab>() {
              @Override
              public void changed(ObservableValue<? extends Tab> observable, Tab oldSelectedTab, Tab newSelectedTab) {
  
  
                  //If we change to the addTab create a 
                  //new tab and change selection.
                  if (newSelectedTab == addTab) {
                      //Create the new tab.
                      createNewTab();
                  } else {
                      currentTab = newSelectedTab;
                  }
              }
          });
          //Create a new tab for initial load of the app
          createNewTab();
  
  
          StackPane root = new StackPane();
          root.getChildren().add(tabPane);
  
  
          Scene scene = new Scene(root, 500, 500);
  
  
          primaryStage.setTitle("Tab Test");
          primaryStage.setScene(scene);
          primaryStage.show();
      }
  
  
      /**
       * @param args the command line arguments
       */
      public static void main(String[] args) {
          launch(args);
      }
  
  
      private Tab createNewTab() {
          Tab newTab = new Tab("New Tab");
          newTab.setClosable(true);
          tabPane.getTabs().add(tabPane.getTabs().size() - 1, newTab);
          tabPane.getSelectionModel().select(newTab);
          return newTab;
      }
  
  
  }
  

  Does anyone have ideas on this? Why it would break in 1.8? Is there a bug in the JDK?

  It's clearly a bug in the code of TabPaneSkin. What seems to be the case, it's that the tab is removed before the end of the deletion tab animation. The problem may be exacerbated by the code by automatically adding a tab if the last tab is deleted, but the code base should not fall like that.

  To work around the issue, disable the close animation of the tab with the following CSS bit.

  tabPane.setStyle ("- fx - close-tab-animation: none ;"); ")

  I created https://javafx-jira.kenai.com/browse/RT-36443 to follow up the matter.

• NullPointerException in screen #navigationMovement Manager

  Hello

  After you add a VerticalFieldManager to a screen, Manager of navigationMovement super screen throws a NullPointerException and the verticalFieldManager scroll with the trackpad of this point (using the Enter key to scroll works very well and after once the trackpad works again scroll).

  I use the same model as this post defining NullField focus on the top and the bottom of the field with vertical scrolling. Has anyone have the same problems, or have any ideas on places of interest to search for?

  I'm sorry, that I couldn't reproduce it with a simple example. After a few hours, I was able to solve the problem by changing the hierarchy of my screen area, adding a handler of accepting high-field the developed anything in it.

  I think what he throwed NullPointerException because he could not find a field of focus when took place the first movement of the navigation, or the system has attempted to lock the focus on an element unfocusable. I have no final conclusion, I could work around it by rearranging the fields.

• NullPointerException when app running, but don't not during debugging

  When I run my app in the Simulator I get a nulpointerexception, but when I debug in the Simulator even I get no exception.  Has anyone seen this behavior before and how can I find the source of the exception?

  I tried this a couple of simulators.  There's a place in my code I know wherever I knocked a nullpointer but this exception is caught by the debugger with a catch (Throwable t) {...} line.  Catch (Throwable) does not work in run mode?

  I use JDE 5, 9550 and 9530 sims, eclipse 3.5.2 plugin 1.1 and compliance of java 1.5

  By adding an extra

  catch (NullPointerException e) {}

  block that now my exception gets handled.  The final catch blocks look like this:

  try{
  ...
  //code that throws nullpointerexception
  ...
  } catch (NullPointerException e) {
      lat=0;
      lon=0;
  catch (Throwable t) {
          lat=0;
      lon=0;
  }
  

  Seems to me the catch (Throwable t) should work in run mode too.  Is NullPointerException not a throwable in run mode?

  -Peter, I did not look into the timing stuff.

• EXECUTE IMMEDIATE throws exception NO_DATA_FOUND when it should not

  Hi all
  
  I wrote an anonymous PL/SQL block that, on paper, should be OK, but one of its commands EXECUTE IMMEDIATE is runnning slowing prematurely and throw an exception NO_DATA_FOUND, when it should not because I know that there is data in the table.
  
  Here is the line that I suspect is out of steam after 8 attempts:
  
  
  ---
  immediately execute "INSERT INTO ple101.circular35 (ID, SLAVETABLEID, SLAVEITEMID, MASTERTABLEID, MASTERITEMID, PRO) (SELECT * FROM SLAVETASKS where mastertableid =' |)" subTableID | "and masteritemid =' |" subitemID |' and subtableid =' | mastTableID | "and SLAVEITEMID =' |" mastItemId |') ' ;
  ------
  
  It is supposed to search the entire SLAVETASKS table for documents that match the WHERE clause, but gives up after 8 cycles.
  Table SLAVETASKS got 10228 records.
  
  The above statement (and the whole of the PLSQL block) is good in that it gets records if they are wthin the first 8 records in the SLAVETASKS table, but like I said after 8 records, to throw an exception NO_DATA_FOUND.

  # Save the code below in the sqlscript for example. circular_process_display. SQL and run as

  sqlplus /@ @circular_process_display.sql

  -- CREATE TABLE circular 35

  /
  
  -- Execute PLSQL Block as given in my earlier post
  DECLARE

  -- Run SQL to display output on screen.
  SET SERVEROUTPUT ON SIZE 100000 FEEDBACK ON LINESIZE 200;
  
  SELECT *

  If I remove the form from the page loads, but then I can't use the inputFile.
  
  Any ideas?
  
  Best wishes in advance.

  If you use regions, then you af:form component in the main page.
  You can have more then one af:form in a page that I know, or at least you can't have nested.
  Why do you need all the af:form? It should work fine without it.

• How to insert data into the database of the fields that have already been assigned values?

  Hi all

  I'm sorry for the question, I'm still new to the OPS

  Here's the thing.

  I have 4 points messageTextInput in my page. each of these 4 field is associated with an attribute of the VO.

  3 of these items have their value already defined in the processRequest of the Commander, like this:

         
        OAMessageTextInputBean factureItem = (OAMessageTextInputBean)webBean.findChildRecursive("factureItem");
        factureItem.setValue(pageContext,pnumfacture);
  
         OAMessageTextInputBean actionItem = (OAMessageTextInputBean)webBean.findChildRecursive("actionItem");
         actionItem.setValue(pageContext,pidaction);
         
        Date sysDate = new Date(); 
         OAMessageDateFieldBean dateSystemItem = (OAMessageDateFieldBean)webBean.findChildRecursive("dateSystemItem"); 
           dateSystemItem.setValue(pageContext,sysDate);       
  

  The user must enter the value of the 4th field.

  I used the classic entry code for data as follows:

  in the AM, I added,

      public void insertRecord(){
      
      OAViewObject vo = getTraceVO1();
      OADBTransaction trans = getOADBTransaction();
      
          if (!vo.isPreparedForExecution()) 
            { 
                  vo.executeQuery(); 
            }
      
      TraceVORowImpl v_row;
      v_row = (TraceVORowImpl)vo.createRow();
      vo.insertRow(v_row);
     v_row.setNewRowState(v_row.STATUS_INITIALIZED);
    }
  public void apply()
     {
        getTransaction().commit();
      }
  

  In the processRequest of the Commander, I added:

        if (!pageContext.isFormSubmission())
          {        
           am.invokeMethod("insertRecord",null);       
          } 
  

  in the processFormRequest of the CO, I added:

        if(pageContext.getParameter("submitButtonItem")!=null){
                       
              am.invokeMethod("apply");
        throw new OAException("Trace Created successfuly",OAException.CONFIRMATION);
        }
  

  When I run my page, I get the error message saying that myVO not records, the records were removed or the view instance has been initialized incorrectly.

  Can someone please tell me what this means?

  Kind regards

  Afaf

  Afaf,.

  Please try to use the code below and see what happens:

  Replace the insertRecord in the AM method with this.

  Import oracle.jbo.domain.Number;

  public void insertRecord(String pnumfacture, String pidaction){ 
  
    System.out.println("been  in insert method");
    OAViewObject traceVO = getTraceVO1();
    OADBTransaction trans = getOADBTransaction(); 
  
    /*if (!traceVO.isPreparedForExecution())
    {
    traceVO.executeQuery();
    }
    */
    traceVO.setWhereClause(null);
    traceVO.setWhereClauseParams(null);
    traceVO.setWhereClause("1=2");
    traceVO.executeQuery();
  
    Number pidAction;
    try{
    pidAction = new Number(pidaction);
    }catch(Exception e) {}
  
    TraceVORowImpl traceVORow;
    traceVORow = (TraceVORowImpl)traceVO.createRow();
    traceVORow.setIdFacture(pnumfacture);
    traceVORow.setIdAction(pidAction);
    traceVORow.DateSysteme(this.getOADBTransaction().getCurrentDBDate());
    traceVO.insertRow(traceVORow);
    //traceVORow.setNewRowState(traceVORow.STATUS_INITIALIZED); 
  
    System.out.println("been  in insert method");
  } 
  

  Replace the processRequest of the second Commander by this:

  public void processRequest(OAPageContext pageContext, OAWebBean webBean)
  {
    System.out.println("first time in processForm of CO2");
    String pnumfacture = null;
    String pidaction = null; 
  
    super.processRequest(pageContext, webBean); 
  
    OAApplicationModule am = (OAApplicationModule)pageContext.getApplicationModule(webBean); 
  
    if(pageContext.getParameter("pnumfacture")!=null)
    {
    pnumfacture = pageContext.getParameter("pnumfacture").toString();
    } 
  
    if(pageContext.getParameter("pidaction")!=null)
    {
    pidaction = pageContext.getParameter("pidaction").toString();
    } 
  
      System.out.println("been  in processRequest before assign variables of CO2"); 
  
    System.out.println("pnumfacture :" + pnumfacture);
    System.out.println("pidaction :" + pidaction);
  
  /*assign values to the 3 fields*/
        /*
     Date sysDate = new Date();
        OAMessageTextInputBean factureItem = (OAMessageTextInputBean)webBean.findChildRecursive("factureItem");
        factureItem.setValue(pageContext,pnumfacture); 
  
        System.out.println("been  in processRequest after assign variables of CO2"); 
  
         OAMessageTextInputBean actionItem = (OAMessageTextInputBean)webBean.findChildRecursive("actionItem");
         actionItem.setValue(pageContext,pidaction); 
  
         OAMessageDateFieldBean dateSystemItem = (OAMessageDateFieldBean)webBean.findChildRecursive("dateSystemItem");
         if(dateSystemItem != null)
         {
           dateSystemItem.setValue(pageContext,sysDate);
         }
         */
      Serializable parameters[] = {pnumfacture, pidaction};
      Class paramTypes[] = {String.class, String.class};
  
         am.invokeMethod("insertRecord",parameters, paramTypes);
         System.out.println("been  in processRequest of CO2 after invokeMethod"); 
  
    }
  

  Let us know what happens.

  You can get an error that I have just change this in Textpad and may have syntax errors. If you can't fix those apply here.

  See you soon

• Could not get CameraDemo as application to work

  I am trying to take a snapshot with MMAPI, based on this article, and also based on the CameraDemo code. I can view the field, then the guests of simulators for a photo. I select the sample, wich becames visible image. There is no other field on this screen, only the field that is returned by VideoControl.initDisplayMode mode full-screen. Then I take the snapshot (triggered from a TrackwheelClick event) and the returned byte array is null. It is a sample of the code:

  // The screen is created, then initialized and pushed: synchronized (Application.getEventLock()) { cameraScr.initScreen();   app.pushScreen(cameraScr);}cameraScr.start();
  
  //CameraScr is a MainScreen, and these are the methods mentioned above:public void initScreen() {    try{                              p = Manager.createPlayer("capture://video");      p.realize();                  p.prefetch();
  
        vc = (VideoControl) p.getControl("VideoControl");     if(vc != null){           viewFinder = (Field)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");            vc.setVisible(true);          vc.setDisplayFullScreen(true);              
  
            deleteAll();                  add(viewFinder);                      } else {          System.err.println(ERR_TAG + "initScreen(): VideoControl is NULL");       }                             } catch (Exception me){       System.err.println(ERR_TAG + "initScreen(): " + me);  }       }
  
  public void start(){   try {     p.start();    } catch (MediaException e) {      System.err.println(ERR_TAG + "start(): " + e);    }}
  
  //The TrackwheelListener overriden method which fires the snapshot: public boolean trackwheelClick(int status, int time) {  snap();   return true;}
  
  //The snap() method:private void snap(){ byte[] imageBytes = null; try {     imageBytes = vc.getSnapshot("encoding=jpeg&width=640&height=480&quality=normal"); } catch (MediaException e) {      System.err.println(ERR_TAG + "snap(): " + e);     imageBytes = null;    } // After this block, no exceptions are thrown, but imageBytes is always null.               }
  

  As you can see, I call Player.start () after the field is added and the screen, following the advice of peter_strange on another post. I also tried calling start() after initDisplayMode (as in CameraDemo) without success. I tried all kinds of stuff, and nobody seems to work.

  Tested with:

  BB - plugin for eclipse, v1.0.0.67, component Pack 4.6.0 ("BOLD" 9000 Simulator)

  -Blackberry 8900 (real device)

  -For the test with the component Pack 4.6.1 (8900 Simulator), I am never invited to an image and the Simulator crashes.

  Needless to say I tested CameraDemo on device (8900) and it doesn't work, but I think it's because there are other fields on the screen.

  OK, I found what happens.

  First of all, old CameraDemo fails due to the button. New CameraDemo (included with JDE 5.0) does not work, but it will throw NullPointerException if it is configured with this coding:

  'encoding = jpeg & width = 640 & height = 480 & quality = normal '.

  Which was originally my app to not too. Now lets change to this other coding:

  "encoding = jpeg & width = 640 & height = 480 & quality = very well"

  And everything works perfectly.

  This happens also on real devices, though I'm afraid that this is a bug. It's really weird because the first coding is among the strings returned by this sentence:

  System.getProperty("video.snapshot.encodings");
  

• Failed to get child node in tree selection listener

  I do a web application using JDeveloper 11 G (11.1.1.2.0) merge.
  
  I created two display objects linked together. Let's call them VoDepartments and VoEmployees, connected by DepartmentId.
  
  I hava done a tree with an af:switcher

  <af:switcher id="s1" facetName="#{node.hierType.structureDefName}">
   <f:facet name="view.VoDepartments">
    <af:outputText value="#{node}" id="ot1"/>
   </f:facet>
   <f:facet name="view.VoEmployees">
    <af:outputText value="#{node}" id="ot2"/>
   </f:facet>
  </af:switcher>

  I made a selection listener based on a guide about Frank Nimphius

  RichTree tree1 = (RichTree) selectionEvent.getSource();
  RowKeySet rks2 = selectionEvent.getAddedSet();
  Iterator rksIterator = rks2.iterator();
   
   if (rksIterator.hasNext()){
    List key = (List)rksIterator.next();
    JUCtrlHierBinding treeBinding = null; 
    treeBinding = (JUCtrlHierBinding) ((CollectionModel)tree1.getValue()).getWrappedData();
  
    JUCtrlHierNodeBinding nodeBinding = nodeBinding = treeBinding.findNodeByKeyPath(key);
              
    String nodeStuctureDefname = nodeBinding.getHierTypeBinding().getStructureDefName(); //Here is the nullpointerexception for employees
            
    String employees = "view.VoEmployees";
    String departments = "view.VoDepartments";
             
    if (nodeStuctureDefname.equalsIgnoreCase(departments)){
     String dept = (String) nodeBinding.getAttribute("Department_name");   
     System.out.println("Department = "+dept);
    }
    else if (nodeStuctureDefname.equalsIgnoreCase(employees)){
     String emp = (String) nodeBinding.getAttribute("First_name");   
     System.out.println("Employee = "+emp);
    }
    else{
     //what the heck did the user click on? Ask him ;-)
    }
   }

  Pagedef:

  Executables:
  <iterator Binds="VoDepartments2" RangeSize="25" DataControl="AppMainDataControl" id="VoDepartments2Iterator"/>
  
  Bindings:
  <tree IterBinding="VoDepartments2Iterator" id="VoDepartments2">
   <nodeDefinition DefName="view.VoDepartments" Name="VoDepartments20">
    <AttrNames>
     <Item Value="DepartmentId"/>
    </AttrNames>
    <Accessors>
     <Item Value="VoEmployees"/>
    </Accessors>
   </nodeDefinition>
   <nodeDefinition DefName="view.VoEmployees2" Name="VoDepartments21">
    <AttrNames>
     <Item Value="First_name"/>
     <Item Value="Last_name"/>
    </AttrNames>
   </nodeDefinition>
  </tree>

  The works of the tree just fine and all he has to list the list. I can click on the Department and my interlocutor selection departments name printed in the console.
  I can develop a Department and the list of employees. The problem is when I click on an employee, I get null pointer exception.
  
  I discovered that the listener selectins is not nodeBiding for employees. NodeBinding.getHierTypeBinding () .getStructureDefName () Yes; throw NullpointerException.
  
  Someone has an idea what is wrong? Help, please.

  Thomas,

  I was able to reproduce the problem and resolved. View objects only reading is not a primary key set. So just change all attributes that participate in a primary key and the value of the 'key' button I'll add a note to the blog post original th
