• IndexOutOfBoundsException is thrown when you try to access the HorizontalFieldManager field

  How can I add several HorizontalFieldManagerss at the same screen -

  The line - getField (3); in below code throws an indexoutofboundsexception. I'm not sure why?

  LabelField l1 = new LabelField ("test");
  LabelField l2 = new LabelField ("test");
  LabelField l3 = new LabelField ("test");
  LabelField l4 = new LabelField ("test");

  {
  ' public void sublayout (int width, int height)
  {
  Super.sublayout (width, height);
  super.setExtent (height, height);

  };
  H1. Add (L1);
  H1. Controls.Add (L2);
  Add (H1);

• IndexOutOfBoundsException and invokeAction

  Hello
  
  I have an IndexOutOfBoundsException trying to rollback and editable table. In my case, I don't want to see "no data found", so I have to createInsert one line if no data is found. I use an involeAction with a refreshCondition for this.
  
  The use case is easy to reproduce:
  
  In the HR schema, create an editable on the job table. Drag n drop the restore as commandButton control action. In pageDef, add a 'createInsert' with if necessary refresh invokeAction:
  

  <invokeAction id="createInsert" Binds="CreateInsert" Refresh="ifNeeded"
                    RefreshCondition="#{bindings.JobsView1Iterator.currentRow==null}"/>

  When you change a line if the user clicks the Cancel button, the exception is thrown:

  Hello

  Hi you can try and dismiss the refresh condition to check that it comes from the EL update? If so, then first of all I would suggest using $ instead of # the EL expression shape # being resolved during the rendering of the user interface that is too late for the affection you need. Second, if the help $ does not resolve the problem, try RefreshCondition = "${bindings." JobsView1Iterator.estimatdRowCount == 0}"/ >

• Custom B-Tree comparer causes IndexOutOfBoundsException

  My apologies, I can't understand how to format the code below.
  
  I created a database that uses a custom comparer of B-Tree for a key whose type is long. The comparator reverse just the sort order for long so that entries with a larger values long for their keys are returned earlier during the iteration.
  
  For some reason, method compares to my custom comparer survey an IndexOutOfBoundsException when trying to insert values.
  
  Configuration of the database:
  
  
  
  EnvironmentConfig envCfg = new EnvironmentConfig();
  envCfg.setAllowCreate (true);
  envCfg.setTransactional (true);
  This.env = new environment (dbDir, envCfg);
  
  DatabaseConfig dbCfg = new DatabaseConfig();
  dbCfg.setAllowCreate (true);
  dbCfg.setTransactional (true);
  dbCfg.setSortedDuplicates (false);
  dbCfg.setBTreeComparator (ReverseLongComparator.class);
  
  Database classDb = this.env.openDatabase (null, "ClassDb", dbCfg);
  this.classCtlg = new StoredClassCatalog (classDb);
  
  this.deploymentDb = this.env.openDatabase (null, "MaBase", dbCfg);
  this.keyBinding = TupleBinding.getPrimitiveBinding (Long.class);
  this.depRecBinding = new SerialBinding < MyRecord > (this.classCtlg, MyRecord.class);
  
  map = new StoredSortedMap < Long, MyRecord.class);
  
  
  
  
  ReverseLongComparator:
  
  
  
  public class ReverseLongComparator implements comparator < byte [] >, Serializable {}
  
  private static final long serialVersionUID = 1 L;
  
  @Override
  public int compare (byte [] o1, o2 byte []) {}
  long k = o1.length == 1? 0: LongBinding.entryToLong (DatabaseEntry (o1) new);
  long k2 = o2.length == 1? 0: LongBinding.entryToLong (new DatabaseEntry (o2));
  
  We want the keys to be sorted most recent first. Switch the order
  the comparison
  Return Long.compare (2 k, 1 k);
  }
  }
  
  
  
  
  Code to store a record:
  
  
  
  public void storeRecord (final MyRecord rec) bird Exception {}
  Worker TransactionWorker = new TransactionWorker() {}
  @Override
  Public Sub doWork() throws Exception {}
  Map.put (Rec.GetId (), Rec.);
  }
  };
  
  runTxnWorker (this.txnRunner, worker);
  }
  
  
  
  
  The error occurs inside ReverseLongComparator. During the first record insertion, the second byte [] o2 has length zero. When the LongBinding.entryToObject is called, the exception is thrown.

  Thank you. The stack trace shows your comparator called when writing to the database of class catalog. I'd know the error in your code as soon as possible:

  DatabaseConfig dbCfg = new DatabaseConfig();
  dbCfg.setAllowCreate(true);
  dbCfg.setTransactional(true);
  dbCfg.setSortedDuplicates(false);
  dbCfg.setBTreeComparator(ReverseLongComparator.class);
  Database classDb = this.env.openDatabase(null, "ClassDb", dbCfg);
  this.classCtlg = new StoredClassCatalog(classDb);
  this.deploymentDb = this.env.openDatabase(null, "MyDatabase", dbCfg);
  

  You use the same configuration of db for class catalog db with respect to your db app. Your comparison tool will not work with the catalog db class.

  You must remove the sbconsole not from the ide projects.
  the ide will sync with the console.

  Close the ide
  Navigate to http://localhost: port/sbconsole > projects and remove all the stuff.
  You again open the ide, clean (just to make sure) the project again and try again

• Exception IndexOutOfBoundsException when trying to deploy

  Hi all

  I am facing a problem when I try to run or debug my app. I made this app in air 1 year ago and recompile with the blackberry sdk (I also integrate some swc libraries that I can't recompile).

  When I try to debug or run that I have an exception message:

  It's questions - bug in Packager - caused by lots of files bundled in your application.

  The work around:

  Do not use the option - airpackager launchApp (or launch of the FB integration options),

  use blackberry - deploy tool (command line), but instead specify package- option, you must explicitly specify - package-name and - package-options id. the package name you need to know (comes from app.xml) but the package id is the unique name generated automatically - you can extract file .bar if you unpack and check the META-INF/MANIFEST. MF for the Id attribute of the Package (also package id is printed on the console when you install the application on the Simulator).

• Calendar events indexoutofboundsexception

  Hi, I get the error on this line:

  Hello, I found the solution to the problem. I firstly all the fields available for the event, then check if the field is something present in this array of integers. If this is the case, you can go ahead with the code otherwise, continue with the enumeration. If you need code, let me know!

  I hope this helps for developers!

  I had a very quick glance, I probably missed or to some things so ignore my comments, if you don't think they are correct.

  A few ' style questions:

  (1) why you substituting delete and deleteAll and using size() instead of getFieldCount().

  (2) for me, the performance benefits to count backwards in loops is over-priced - and the confusion it can cause in the coding is often overlooked.

  (3) you sublayout loop backwards and the loop count seem to do essentially the same thing, is there a reason they are separate?

  (4) I don't know that you have understood the concept of a virtual height and the height of the screen for a manager of scrolling.  Your sublayout seems to try to limit the number of fields displayed in the size of the actual scope and assume that this will continue after your currentIndex.  Take a look at this:

  http://supportforums.BlackBerry.com/T5/Java-development/implementing-a-standard-style-scrollbar-on-a...

  That said, it seems to be a problem with your maintenance of currentIndex when you remove fields. Whenever you remove the field, it will cause a sublayout, and once currentIndex is > that the number of fields on the left, your treatment will die with an output of exception of limits.  But in sublayout, not delete.

  Perhaps you could explain what you're actually trying to do with this Manager as it is is not clear to me from the code.

• Data storage local application?

  Hi all.

  I want to store the data of the application installed on the PlayBook.

  Anyone knows where is this dedicated space and how to access?

  The main use is to use a SQLite database (but not only).

  (What is possible with the simulator at all?)

  [Edit: the message is more specific.

  Hello Julien, thanks for the reply.

  In fact I tried to use ApplicationStorage already, but I got a 3003 error: exception "file or directory does not exist.

  When I run the App in internal Flash Burrito Simulator, there is no error: the db file is correctly detected.

  But it seems that File.applicationStorage is not on the PlayBook Simulator.

  Is there a simple test to check the correct path to the App store?

  [Edit 1]

  Some news: I could verify that the ApplicationStorageDirectory is finally ok (correctly created in the card Sim PlayBook.)

  The problem actually comes from ApplicationDirectory, where I get the "source" file load in the dbFile.

  If the command "File.applicationDirectory.resolvePath("assets/MyFile.ext"); ' return something like:

  "/ mlc/sandboxes/guest/PROJECTNAME.debug.XXXXXXXXXX/app/air/assets/MyFile.ext".

  (XXXXXXXXXX seems to be the ID of the deployed project series)

  And if this file "does not exist" when I access it.

  (reminder: it works very well in the internal Flash Simulator)

  Is there a simple test to check the correct path of the deployed application. ?

  (always to research...)

  [Edit 2]

  Well, it seems that the solution was related to the embedded file (or not) during deployment.

  So I have included the file I need (xml file) in the line of command deployment, and it was found correctly on the PlayBook, using ApplicationDirectory (as described by Julian).

  Just for review, I first tried to include the 'active' comprehensive directory, with an error that results from:

  java.lang.IndexOutOfBoundsException  at java.io.ByteArrayOutputStream.write(Unknown Source)    at com.qnx.bbt.deploy.Deploy.readPackage(Deploy.java:173) at com.qnx.bbt.deploy.Deploy.verifyPackageId(Deploy.java:138) at com.qnx.bbt.deploy.Deploy.sendRequest(Deploy.java:124) at com.qnx.bbt.deploy.Deploy.run(Deploy.java:100) at com.qnx.bbt.deploy.Deploy.main(Deploy.java:73) at com.qnx.bbt.airpackager.BarAirPackager.callLauncher(BarAirPackager.java:206)   at com.qnx.bbt.airpackager.BarAirPackager.run(BarAirPackager.java:129)    at com.qnx.bbt.airpackager.BarAirPackager.main(BarAirPackager.java:78)Error: null
  

  (It may be related to a specific inside assets... file or directory size... but this isn't a big deal)

  Then, finally solved. Would be the last word: do not forget to include the 'active' files you need!

• navigationMovement puzzle

  I write my own field Manager to display a grid of 6 x 10 fields. The first column is not active (done via the individual fields), and I try to have thefocus wrap around the screen. For example, if move you to the right of the last column, focus should move to the 2nd column. In other words, I want 1-5 fields below to behave like a circle under the left-right movement.

  [ X ] [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ]

  Up and down should behave like in a regular gridfieldmanager. For various other reasons, subclassing the GridFieldManager is not an option, so I'm subclassing Manager directly. I have this scrolling behavior works correctly. the problem arises when the focus would let the Manager. If I pressed ENTER, the default scrolling down works perfectly. When I scroll with the wheel, however, development is blocked in the first and last lines. This scrolling down with the emphasis on the field (line 9, column 4) doesn't help, as does the scroll upward on the ground (row 0, col 2).

  I thought to use getManager (.navigationMovement), but it is protected.

  My navigationMovement method:

  protected boolean navigationMovement(int dx, int dy, int status, int time){    int index = getFieldWithFocusIndex();
  
      while(index >= 0 && index < getFieldCount()){        if (dx*dx > dy*dy){ // horizontal motion            if(dx < 0){ // left                index += (index%cols == 1) ? cols - 2 : - 1;            } else{ // right                index -= ((index+1)%cols == 0) ? cols - 2 : -1;            }        }else{ // vertical motion            if(dy > 0){ // down                index += cols;            } else{ // up                index -= cols;            }        }
  
          if(index < 0 || index >= getFieldCount()) return false;        try{            getField(index).setFocus();            return true;        } catch (IndexOutOfBoundsException ioobe) {            // We hit a blank spot, cycle again        }    }    return false;}
  

  Thanks in advance!

  So this is my attempt to help moveFocus. As it does not keep track of direction or whatever it is, I guess you meant to call me from navigationMovement. It worked perfectly, except that I had to manually scroll Senior Manager, whenever the target subfield was outside the visible area. Here is my solution (which also fixed another problem: the old method scrolls with a single click; now most big dx and dy lead to more scrolling).

  protected boolean navigationMovement(int dx, int dy, int status, int time){    int index = getFieldWithFocusIndex();    int oldCol = index % cols; // index = row * cols + col
  
      dx = dx % (cols - 1) + cols - 1; // force dx positive    int newCol = (oldCol - 1 + dx) % (cols - 1) + 1;    int delta = newCol - oldCol + (cols - 1) * dy;
  
      delta = moveFocus(delta, status, time);    if(delta == 0) {        Manager mgr = getManager();        XYRect rect = new XYRect();        mgr.getFocusRect(rect);        int vscroll = mgr.getVerticalScroll();        int height = mgr.getVisibleHeight();
  
          if( rect.y < 0 ) { // scrolled above visible region            mgr.setVerticalScroll((int)Math.max( 0,                         vscroll + 3 * rect.y));        } else if ( rect.Y2() > height ) { // scrolled below screen edge            mgr.setVerticalScroll((int)Math.min(                    mgr.getVirtualHeight(),                    3 * (rect.Y2() - height) + vscroll));        }    }    return (delta == 0);}
  

  Thank you very much!!

• Problem with the playback of the ToDo of ToDoList items

  Hello

  I'm at the end with my knowledge about a problem when I try to read some fields from the list of ToDo and ToDo native application.

  I don't have a problem to read for example the name of a ToDo item with the following code:

  String taskName = task.getString(ToDo.SUMMARY, PIMItem.ATTR_NONE);
  

  But when I try to read the finished field, I always get and IndexOutOfBoundsException. The reason is that I am doing something wrong with the index, the second attribute. Here is the code:

  boolean taskStatus = task.getBoolean(ToDo.COMPLETED, 0);
  

  I found examples how to create a new item Todo, but how do I read a Boolean value in the ToDo list?

  I'm at the end with my knowledge, maybe someone of you can help me, thank you already in advance

  
  

• 9800 tilt - screen drawing problem?

  I did a screen with custom graphics, it works perfectly normal up-side-face upward, however when I tilt the Simulator or even a real device to the left or right screen becomes white and no fields or graphics on the screen are displayed.

  Interestingly, if I start the app when the Simulator is already left-coast-to the top then the screen is however as soon as I drew with the fields etc., tili unit right-side-up top, the same thing once again, a white screen. If I restart the device in the top left-side-up mode and tilt in top-side-to the top of the screen works in the high-side-to the top, but after the back passage to left-side-to top (the State that the application started first) again a white screen.

  You don't need to invalidate - the system redraws after a re-layout anyway.

  What to use as values for width and height - only maxWidth and maxHeight spent in your sublayout are correct. getPreferredWidth and getPreferredHeight are still useless. getWidth() and getHeight() return the previous values, since you have not called setExtent with new values yet. Same problem with getVisibleWidth / getVisibleHeight. Oh and by the way, you cannot use correctly titleField.getHeight () at this point as well.

  However, the irony is that you don't need all these shenanigans in your program. Instead of making your first the 'title' field, don't add it to the screen at all and just use setBanner / setTitle on it. You will be able to abandon this override of sublayout in total.

  Read the following article in the knowledge base to greatly simplify your code:

  Screen explained

  Oops - just found another problematic piece of code: why any who call the super.paint inside paintBackground? Drop this last line, and you'll be much better off. It could well be the root of your problem.

  Also - for efficiency, not to generate your image Bitmap every time by the paintBackground - do once in the constructor and use it whenever you need.

• To access the news PIM works on OS 4.2-4.5 but fails on OS 4.6

  I use this code to access the information memo on 8800 4.2 and 4.5 8800 and it works but when I use it on flat bead with 4.6 I get a 'java.lang.IndexOutOfBoundsException"when it is called custom MenuItem that I added in memo app.

  //Run is called when the custom menuItem is invoked
  
  BlackBerryMemo memo;
  
  public Object run(Object context){  //context object should be a memo         if (context instanceof BlackBerryMemo)   {        try{                _myBuffer.append("Notes ID: " + memo.getString( BlackBerryMemo.UID, 0 ) + "\r\n" );}  catch (Exception e) {System.out.println(e);}   }   return context;}
  

  The strange thing is that if I use this code:

  _myBuffer.append("Notes ID: " + memo.getString( BlackBerryMemo.UID, 0 ) + "\r\n" );
  

  in a regular application of CLDC "don't not using custom menu" the same code works on the flat bead.

  someone at - it a similar experience?

  Ugh... Add this code works:

  if ( memo.countValues( BlackBerryMemo.UID ) > 0 )
  {
     _myBuffer.append("Notes ID: " + memo.getString( BlackBerryMemo.UID, 0 ) + "\r\n" );
  }
