• Put two ObjectChoiceField side by side

  Hello

  I tried to put both components in a HorizontalFieldManager ObjectChoiceField, but I can't view both on the same line, it seems that the other is pushed off the screen to the right.

  I tried with Manager.NO_HORIZONTAL_SCROLL nothing works.

  Can anyone please help me;

  Thank you very much

  You can limit the width of one of them. These two talk on this subject, but for the different types of fields:

  But if you are sure that they will hold next, you can set one on the left with the style

  Field.FIELD_LEFT and I think he'll try to stay as close to the left as it can.  Give it a try.

• pushed single screen several times on display battery but can not go back to the previous screen again by clicking on "back" to come to the first screen button

  Hi all

  There is a screen with meter as label, datefield and objectchoicefield in the menu drop down and add and go button, this screen is pushed repeatedly on display battery until the meter is new. But when I try to go back to the previous screen, there is problem normally by substituting the onClose() method you can pop current screen and can get the previous screen, using getActiveScreen() and then push it again if you do not override os onClose() automatically do it for you.

  But in above case when I click on the button "back" or screen previous override onclose and push, I see my first screen I wanted my current screen with the counter that is if active screen is having against label like new if I press the "back" button, it should display screen with the meter only eight and so on.

  Can someone please help me solve this problem.

  Thanks Peter for you answer, actually used function for pushscreen on stach display that was written by someone else, when I looked carefully there condtion as below,

  if (activeScreen != null) {
   Class screenClass =activeScreen.getClass();
      if (screen.getClass().equals(screenClass)) {
                      UiApplication.getUiApplication().popScreen(activeScreen);
      }
  }
  

  It's actually the previous screen of poping before push the screen from the class were same, just commented and everything works, even if you do not override onClose and press return, it will automatically displays the previous screen.

  Can anyone give reason to that, suggests a solution that works for all Blackberry OS?

  I don't know why on each new version of OS RIM of new bugs. I don't speak of situations, these are fairly straightforward scenarios, the OS 5 they SMS API not working and now in the box of 6 option OS not showing.

  If there is a team of QA to the RIM, I do not understand what RIM by paying them.

  I got it to work. This is a bug of Blackberry OS 6, if you have two radio buttons in a HorizontalFieldManager, it wouldn't show the other. You just need to extend the RadioButtonField and use it instead of the original.

  class RadioButtonFieldPatch extends RadioButtonField
  {
      RadioButtonFieldPatch(String label)
      {
          super(label);
      }
  
      RadioButtonFieldPatch(String label, RadioButtonGroup group, boolean selected)
      {
          super(label, group, selected);
      }
  
       protected void layout(int width, int height)
       {
           int pWidth = this.getPreferredWidth();
           setExtent(pWidth, height);

  Tanks

  Your options is not initialized, then the exception generated can be different.

  Once you have your number, initialize the array:

  opcoes = new String[count];
  

  Then, you can use the newly allocated array.

• HorizontalFieldManager skins ObjectChoiceField

  Hello

  I use a standard HorizontalFieldManager and ObjectChoiceField in my application.

  I add a TextField to the HorizontalFieldManager and then the ObjectChoiceField, I do this rather than using the label of ObjectChoiceField I can 'space' label of choice.

  However, when I do that the ObjectChoiceField is not visible on the screen, blurred or the focus, but it is there because if I focus on it and press the trackball, I can see the choices.

  I beleve I had added the HorizontalFieldManager and the ObjectChoiceField otherwise I would not have the choice.

  Could the ObjectChoiceField paint method be called not because it's in a HorizontalFieldManager?

  Thank you

  David

  I think that the TextField object that can use the full available width, which will push the ObjectChoiceField off the screen to the right. Instead of a TextField, try a RichTextField using the USE_TEXT_WIDTH style. (Which won't help, of course, if the text is too wide for display.) Otherwise, you could eliminate the TextField and set the label of the ObjectChoiceField the text you want to display.

• 2 at the same HorizontalFieldManager DateFields

  Hello everyone

  Is it possible to have 2 DateFields in HorizontalFieldManager even?

  I tried the following code, did not work.

  Dtfm DateFormat = new SimpleDateFormat("HH:mm");
             
  HorizontalFieldManager hmDisable = new HorizontalFieldManager();
  HorizontalFieldManager hmFrom = new HorizontalFieldManager();
  HorizontalFieldManager hmTo = new HorizontalFieldManager();
             
  dtStart = new DateField ("disable:", System.currentTimeMillis (), dtfm);
  dtTo = new DateField ("disable for:", System.currentTimeMillis (), dtfm);

  hmFrom.add (dtStart);
  hmTo.add (dtTo);

  hmDisable.add (hmFrom);
  hmDisable.add (hmTo);
              
  Add (hmDisable);

  Thank you

  Never mind. I solved it by replacing sublayout.

• DateField as itemrender causes Error #1034: Type coercion failed: cannot convert '10/03/2006.

  I have itemrende onliner.

  < mx:DataGridColumn dataField = "solddate."

  Is it possible for me to be

  or

  2 convert the data within the itemrenderer

  The answer is here http://blog.flexmonkeypatches.com/2008/04/08/datefield-itemeditor-when-date-is-a-string/comment-page-1/
  
  or you can do it inline like

• DataGrid, error using DateField as the post editor

  Hello
  
  I am trying to create a DataGrid editable using Flex 2.0.1. One of the columns is of type Date, so I want to use a DateField as the item editor.
  
  The problem is that I get an error when the focus is removed from the DateField:

  I managed to do works by adding the editorDataField = "selectedDate" attribute to the element of DataGridColumn, even leaving the attribute date of birth on the VO as public Date variable.

  Thanks anyway for the help.

• ObjectChoiceField throw a Null pointer Exception error

  Could someone help me please.  I have an ObjectChoiceField object that throws a null pointer exception and I know there was another post but I don't yet understand why.  This is how I create the object and fill it with four points.  Thank you!

  lv_loc1 = "Arlington Heights";
  lv_loc2 = "Waterloo."
  lv_loc3 = 'Fort Madison';
  lv_loc4 = "Colorado Springs";
  String [] lv_locs = {'Loc1-' + lv_loc1, 'Loc2-' lv_loc2, 'Loc3-' + lv_loc3, '-Loc4' + lv_loc4};
  int lv_start_psn = 0;
  ObjectChoiceField lv_locChoice = new ObjectChoiceField ("", lv_locs, lv_start_psn, LabelField.FIELD_HCENTER)
  {
  public void layout (int width, int height)
  {
  Super.Layout (lv_btn_width, lv_btn_height);
  setExtent (lv_btn_width, lv_btn_height);
  }
  };

  Here's how I'm trying to get the selected item

  lv_str = (String) lv_locChoice.getChoice (lv_locChoice.getSelectedIndex ());

  I know that it should be a simple way to do it, here is what I finally realized. It returns the index value to the lv_choice_sel variable, which is a variable so now I can use it throughout the app.

  --------------------------

  String [] lv_locs = {lv_loc0, lv_loc1, lv_loc2, lv_loc3, lv_loc4, lv_loc5};
  int lv_start_psn = 0;
  lv_locChoice = new ObjectChoiceField ("", lv_locs, lv_start_psn)
  ObjectChoiceField.FIELD_HCENTER | ObjectChoiceField.USE_ALL_WIDTH)
  {
  protected void fieldChangeNotify (int context)
  {
  lv_choice_sel = Integer.toString (getSelectedIndex ());
  If (lv_choice_sel is nothing)
  {lv_choice_sel = '0' ;}
  }
  };

          positionChoice = tmtth.choiceGenTwo("Time Position Display", topOrBottom, ChoiceOne);
  

  The error occurs after that I start my Save menuitem that is the following code:

              rs.put(HomeScreen.MY_DATA_ID_OPTIONS, hs);
              tmtth.onClose();
  

  Cast you to integer first in the code block when you pull, it forms the hash table.

  choiceOne = (Integer)Data.get("timeposition");

• Error "Index out of range" on search query

  I have a configuration of search query to clear my listview and insert new results of the query in the listview. The code looks like this:

  {OnDataLoaded}

  _APP. Clearlist

  root. ListView.insertlist (Data)

  }

  {OnQueryChanged}

  Load();

  }

  But unfortunately, whenever I do a query, and as a result appears my query update (triggered from a contextual menu) does not work and gives me the error "Index out of range". Even if the results of the query to fill listview very well and when I tap on a result it shows all data fine as well.

  And FYI the update query does not work when the list is not be searched or filtered so I don't think that there is a problem with my function.

  What I am doing wrong?

  He solved.  The problem is that the update function trying to remove and add the updated item within the filtered datamodel causing problems.  I just got the datamodel to load before performing the functions as described below:

  bool App::updateObject(const QString &id, const QString &name, const QString &description, const QString &datefield, const QString &lat, const QString &lon, const QString &categoryfield, const QString &mapurl, const QString &itempic)
  {
      bool updated = false;
      bool saved = false;
  
  //    if (!validateID(id))
  //        return false;
  
      Location *location = new Location(id, name, description, datefield, lat, lon, categoryfield, mapurl, itempic);
  
      // Find location in the datamodel.
      // Only the id is used by find(). This is because location
      // defines equality (==) as having the same id. (See the definition of "=="
      // in the location class.)
      const QVariantList updateIndexPath = m_dataModel->find(location);
  
      // update the item if found
      if (updateIndexPath.isEmpty()) {
          alert(tr("Object ID not found."));
          updated = false;
      } else {
          load();
          updated = m_dataModel->updateItem(updateIndexPath, location);
      }
  
      // Save the datamodel if we updated something.
      if (updated) {
          m_storage->deleteFromDB(id);
          saved = m_storage->save(m_lastCustomerID, m_dataModel);
