• refresh of data binding problem

  Hello

  I am a beginner in Flex, and I have a problem with data binding. I have this little program:

  <? XML version = "1.0" encoding = "utf-8"? >
  " < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML "layout ="absolute"> "
  < mx:Script >
  <! [CDATA]
  [Bindable] public var value: String;
  []] >
  < / mx:Script >

  < mx:ViewStack id = "mainViewStack" width = "100%" height = "100%" >
  < mx:Panel id = "panel1" >
  < mx:TextInput id = "text1" / >
  < mx:Button label = "A" click = "value = 'test'; mainViewStack.selectedIndex = 1; "/ >
  < / mx:Panel >
  < mx:Panel id = "panel2" >
  < mx:TextInput id = "text2" text = "{value}" / >
  < mx:Button label = "B" click = "mainViewStack.selectedIndex = 0; "/ >
  < / mx:Panel >
  < / mx:ViewStack >
  < / mx:Application >

  -J' I spend 2 panels ('A' button).

  -When I go to the panel1 to panel2 (click on event), I change the variable 'value' for 'test' (with data binding, Text2 is updated).

  -After this, I manually change the value in Text2 (for example "valeur123").

  -J' I spend panel2 to panel1 (button 'B')

  -J' I go once more of the panel1 to panel2 ('A' button)

  = > and this time, the "Text2" TextInput is not being updated. the value is not changed (always "valeur123").

  So why the data binding does not work in this case?

  Thank you for your help.

  Yes you were not trying to bind your data to 2 channels, but I said that because assumes that if you have two way data binding support now, so know you only problem.consider the following two lines, which run two way data binding

• BB10 Image problem

  I encountered a problem trying to update a qnx.fuse.ui.display.Image bitmapData:

  Here is my code:

  function update( bmp:Bitmap ):void{ var bmd:BitmapData = bmp.bitmapData;
  
      if ( bmd is BitmapData )
      {
          trace( _image.width, "x", _image.height, bmp.name, bmd.width, "x", bmd.height );
  
          _image.setImage( bmd );
          _image.visible = true;
  

  and here is the trace output:

  329 x 256 instance1872 341 x 256
  ArgumentError: Error #2015: Invalid BitmapData.
      at flash.display::BitmapData/get width()
      at qnx.fuse.ui.display::Image/getRawPreferredSize()[E:\hudson\workspace\BB10_0_09-AIR_SDK_API\src\qnxui\src\qnx\fuse\ui\display\Image.as:142]
      at qnx.fuse.ui.display::Image/setImage()[E:\hudson\workspace\BB10_0_09-AIR_SDK_API\src\qnxui\src\qnx\fuse\ui\display\Image.as:337]
  

  The new bitmapData seems to be ok, because the height and width are non-zero, so it seems to go to a previous instance of bitmapData (which has been replaced).

  I tried to keep a global reference to the old bitmapData, but same result...

  Suggestions please...

  to fix this, I added the following:

  if ( _image.bitmapData )
  {
      try
      {
          var testWidth:int = _image.bitmapData.width;
      }
      catch( e:Error )
      {
          var index:int = getChildIndex( _image );
  
          trace( "remove image at:", index, _image.x, _image.y, _image.hAlign, _image.vAlign );
  
          removeChildAt( index );
  
          _image = new Image();
          {
              _image.fixedAspectRatio = true;
          }
          addChildAt( _image, index );
  
          invalidateDisplayList();
      }
  }_image.setImage( bmd );

• BB10: ListView problem background elements

  Hi guys,.

  

  I have a listview which elements have origins are different colors (see figure). Each element background color depends on a specific element of the element in the data model (say ListItemData.color).

  But for some reaason, when I scroll to the bottom of the list and scroll to the top, the background changes color. I do not understand this weird behavior.

  People you have an idea about what is happening on or at least how to solve?

  Thank you!

  Hi all

  I solve it by doing this:

  Label
  {
      visible: false
      text: ListItemData.id
  
      onTextChange:
      {
          root.background = ListItemData.color;
      }
  }
  

  It's not elegant at all, but at least it works. The 'id' the ListItem is the only single member. So evertytime this invisible label text changes with the new id, it resets the background for that particular item.

  It is a pity I have to use such a solution for this problem.

  Thank you all!

• ADF table with checkbox refresh data binding problem

  Hello.
  
  I use JDeveloper 11.1.1.3. I need to use the table with checkboxes in each row of the table in my project. I use VO with transitional 'Selected' attribute that has a boolean type.
  Everything works well, wait one thing:
  When you click checbox with valueChangeListener and try to get the selected line in the managedBean you won't get any selected lines. After selecting second maaged bean evil shows that 1 single line is selected. It's my managedBean method:
  
  public void SelectCountyClick (ValueChangeEvent valueChangeEvent) {}
  
  DCIteratorBinding it = ADFUtils.findIterator (ITERATOR_NAME);
  
  int selectedRowCount = 0;
  RowSetIterator laughs = it.getRowSetIterator ();
  Line r = rit.first ();
  If (r! = null) {}
  If ((Boolean) r.getAttribute ("Selected"))
  selectedRowCount ++;
  }
  
  While (rit.hasNext ()) {}
  r = rit.next ();
  If ((Boolean) r.getAttribute ("Selected"))
  selectedRowCount ++;
  }
  
  System.out.println ("selected all THE LINES:" + selectedRowCount);
  
  
  }
  
  I tried to change this event to the client event, I got the line number, I put 'true' or 'false' to the code data binding, but whenever I can't correct data after the value change event.
  
  Please help me.
  
  The latest idea is updated databing after click of checkbox, I think. Please help me.
  
  Thank you!

  You must go through the concepts of life cycle of page ADF. In simple terms the Boolean value in the model is not defined in valueChangeListener. Try adding (.processUpdates) valueChangeEvent.getComponent (FacesContext.getCurrentInstance ()); on top of your listener method and see the effect.

• Object binding problem which is not serializable clustered JNDI

  Hello
  
  I have an ApplicationLifecycleListener class that has a preStart() method that instantiates one object & JNDI binds.
  
  This object is a reference to an object that is not Serializable (progress.message.jimpl.Connection).
  
  When I bind it on a single server (without clusters), everything works fine, when I move to a clustered environment, I get the
  
  java.io.NotSerializableException: progress.message.jimpl.Connection
  
  I clear the weblogic.jndi.WLContext.REPLICATE_BINDINGS = 'false' to try and get around that, but no luck.
  
  Please can someone explain why the exception occurs in a cluster but not in a single server environment?
  
  Thank you very much
  
  Mandy

  Hi Mandy,.

  As you have found the InitialContext as follows:

  InitialContext ic = new world; Which is the best way to get the InitialContext when the Code is running on the same JVM (which means same WebLogic Server) when you try to link your objects... This means that the class of the Module Loader already has the class Employee Loaded inside. That is why your code is able to bind in the same WebLogic Server.

  But when you go pass the Argument to the InitialContext as Context.PROVIDER_URL, then you could point the URL of another WebLogic Server... .then when we want to link an object to a remote JVM (WebLogic Server) in this case the object of Marshelled (serialized) be sent to the JVM (WebLogic JNDI tree)... As your employee class is not serializable if the process have will fail and will give you "java.io.NonSerializableException".

  Rule of thumb as well: * "If you want your objects to pass to a distance JVM in this case the class must implement java.io.Serializable interface."

• DataGrid data binding problems

  I'm trying to create a DataGrid control in code and fill it with information. The final product, that I am creating is a form that displays the files you have selected after the navigation of your computer. I intend to place the FileReferenceList table informaiton which will become the dataProvider of the DataGrid.
  
  Would be it someone please let me know what I am doing wrong, or provide a link to an excellent resource on how to create and use DataGrids with Actionscript 3?
  
  I get the following error;
  
  "ArgumentError: Error #1063: incompatibility of County Argument...". »
  
  This error occurs during the process of binding the dataProvider method.
  
  Here is an example of the relevant code, I try to use;
  
  var _dgFiles:DataGrid = new DataGrid();
  _dgFiles.allowDragSelection = false;
  _dgFiles.AllowMultipleSelection = true;
  _dgFiles.resizableColumns = false;
  _dgFiles.sortableColumns = false;
  _dgFiles.percentWidth = 100;
  _dgFiles.percentHeight = 100;
  
  var aColumns:Array = _dgFiles.columns;
  
  var dgcIcon:DataGridColumn = new DataGridColumn();
  var dgcName:DataGridColumn = new DataGridColumn();
  var dgcSize:DataGridColumn = new DataGridColumn();
  var dgcFile:DataGridColumn = new DataGridColumn();
  
  dgcIcon.headerText = "";
  dgcIcon.dataField = "icon";
  dgcIcon.width = 26;
  dgcIcon.editable = false;
  dgcIcon.resizable = true;
  dgcIcon.visible = false;
  
  dgcName.headerText = 'file ';
  dgcName.dataField = "name";
  dgcName.editable = false;
  dgcName.resizable = true;
  
  dgcSize.headerText = "size";
  dgcSize.dataField = "size";
  dgcSize.width = 50;
  dgcSize.editable = false;
  
  dgcFile.headerText = "Data";
  dgcFile.dataField = "data";
  dgcFile.wordWrap = false;
  dgcFile.editable = false;
  dgcFile.visible = false;
  
  aColumns.push (dgcIcon);
  aColumns.push (dgcName);
  aColumns.push (dgcSize);
  aColumns.push (dgcFile);
  _dgFiles.columns = aColumns;
  
  addChild (_dgFiles);
  
  var a1:Array = new Array({icon:"*.jpg",name:"FileName1.jpg",size:10002,data:"TEST1"});)
  var a2:Array = new Array({icon:"*.jpg",name:"FileName2.jpg",size:10002,data:"TEST2"});)
  var a: Array = new Array();
  a.push (a1);
  a.push (a2);
  _dgFiles.DataProvider = a;
  
  That is, it fails. I think that my test table 'a' is not correct. How can I provide the correct information for the
  DataGrid so that it works?

  I think that there is a mistake where you are combining tables:

  a.push (a1);
  a.push (a2);

  actually creates a table to 2 dimensions, instead of concatenated in a single table. Is that what you wanted?

  For a datagrid control, you want a table/collection ArrayCollection of objects.

  I copied and pasted your code and changed the table to this part:

  var data: Array = new Array)
  {icon: "*.jpg", name: "FileName1.jpg", size: 10002, data: 'TEST1'},
  {icon: "*.jpg", name: "FileName2.jpg", size: 10002, data: 'TEST2'}
  );

  _dgFiles.DataProvider = new ArrayCollection (data);

  And he works as (I think) you want.

• binding problem

  I'm sorry to ask it for the millionth time, but I can't seem to access my story on this forum to find the answer.

  http://jordankrose.com/Index_Download.html

  The orange button link shows a white background; I want that have no background.

  Thanks in advance-

  Carrie

  Add class to any top of page

  tag as below:

  top of page

  Then add this piece of css to your page or your style sheet.

  . Back to top a {}

  background-color: transparent;

  color: #fff;

  }

  I suspect it is the css selector that is damage, it's in your stylesheet newstyles.css. (as well as conclusions Kens in the answer above, it seems you want to adjust any link on the page/s to have a white background - a: link)

  . Download img has, a: link {}

  background-color: #FFF;

  }

  as long as you add add new .back css upward after the link to your newstyles.css he should cancel this selector.

  or if you do not want the links to be sure to have a white background just delete - a: link:

  IMG .download a {}

  background-color: #FFF;

  }

• Binding problem rising switch distributed - vim.dvs.DistributedVirtualPort is not available

  Hi all

  I am trying to add a physical link to a distributed switch rising.

  The story unfolded as shown below:

  -default ESX 4 generation created with virtual switch 'standard' with Teddy 0 uplink port & console running through this switch

  -new distributed switch created with groups of separate ports for console, VMkernel and VM traffic

  -Teddy switch 1 assigned as an uplink for distributed

  -new console and VMkernel ports created successfully on the distributed switch

  -console legacy & VMkernel ports correctly migrate from 'standard' virtual switch with for the distributed switch

  -removed 'redundant' console & VMkernel ports to the distributed switch, so there is only one of each kind on the left

  -' standard' virtual switch was successfully deleted

  -When you try to add Teddy 0 (which is displayed as unclaimed) as the second uplink to the distributed switch following error occurs:

  The resource vim.dvs.DistributedVirtualPort is not available in vim. DistributedVirtualSwitch dvSwitch

  Tips / advice / suggestions?

  Kind regards

  Radek

  You can update the number of dvUplinks in the properties of the dvSwitch in stock-> Networking.  Select the switch (icon with the + / according to him, not the object of the child).  It'll be here in the General settings.  You can also change the names of of the uplinks from here.

• Something corrupt in my system like everytime I try to load a program loads Excel tries to open the. EXE

  Whenever I try to load a program, for example - Word, Outlook, painting, etc., etc., Excel seems to try to open the program file that I selected.

  I guess something has become corrupted, in which case the system think something ending with. EXE must be opened with Excel.  I looked in the file Explorer-> tools-> Folder Options-> File Types, but .exe is not listed (as it is does not thank God).

  I also tried Run and accessing a. EXE to see if it works, but Excel still trying to open the .exe file.

  I've been playing with an attempt to paste the shortcut in the start list Excel, until I read on the axis 'in the start list.  But can't see how to do a Ctrl + V shortcut in the choke should have had this effect.

  Someone at - it ideas on how to get back to be able to load the programs?

  Thanks in advance.

  You probably need to restore your .exe file associations (as you suspected it).  Follow the instructions on this site, paying special attention to the note at the top to take care. EXE in particular binding problems.

• HotSync of Palm M515 of replacement

  I've been using Palm for many years and the death of my previous machine

  I bought a second hand M515-

  I tried to hotsync with Palm 6.2.2 that is on my computer and

  that contains my personal data...

  It seems to be a binding problem here that Hotsync does everything just for me...

  I read all the info from Palm I can find and I go round in circles.

  Am hoping there may be someone out there who can give me some advice please...

  Hello leatherwood, welcome to the Palm support community.

  More information is needed to help you.  What OS is on your computer?  XP?  Vista 32 bit?  Vista64bit?

  If Vista 32 bit, have you read this thread? :

  http://forums.Palm.com/Palm/board/message?board.ID=windows_hotsync&thread.ID=38625&jump=true

  You said it was second hand.  Did perform you a Hard Reset to clear all the precedents of the user data?  If this is not the case, the device will never find your data on your PC as it will search other user's data.   Hard Reset of the device, then when you perform a Hotsync tell him to "Use existing account" and choose your initial user name from the list.

• Error 1021: Double Definition function.

  Hello I have a small problem... I want to do different buttons 2-5, but have the same script action.
  1 is perfect using the code. but when I do another button and duplicate the action script to bind.
  problem occupation error 1021: duplicate function definition.

  Here is my code:

  -----

  playPauseToggle_mc.addEventListener (MouseEvent.CLICK, fl_togglePlayPause);

  function fl_togglePlayPause(evt:MouseEvent):void

  {

  If (playPauseToggle_mc.currentLabel is "play")

  {

  playPauseToggle_mc.gotoAndStop ("pause");

  }

  Else if (playPauseToggle_mc.currentLabel == "Paused")

  {

  playPauseToggle_mc.gotoAndStop ("play");

  function fl_togglePlayPause(evt:MouseEvent):void

  {

  If (playPauseToggle2_mc.currentLabel is "play")

  {

  playPauseToggle2_mc.gotoAndStop ("pause");

  }

  Else if (playPauseToggle2_mc.currentLabel == "Paused")

  {

  playPauseToggle2_mc.gotoAndStop ("play");

  }

  }

  ----

  Please help me with this one. Thank you in advance.

  The main problem with what you have done is exactly what means the error message.  You define two different functions with the exact function of the same name... fl_togglePlayPause

  If you were to rename the function second to be fl_togglePlayPause2, then that would solve this problem.

  But for the code, you are showing you could just as easily have all the buttons use the same unique function if you rewrite just that work a little to be generic by using the event information...

  function fl_togglePlayPause(evt:MouseEvent):void

  {

  var toggleBtn:MovieClip = MovieClip (evt.currentTarget);

  If (toggleBtn.currentLabel is "play")

  {

  toggleBtn.gotoAndStop ("pause");

  }

  Else if (toggleBtn.currentLabel == "Paused")

  {

  toggleBtn.gotoAndStop ("play");

  }

  }

  With this approach simply the defined function and all your buttons can share.

• XML - a list of possible values for filtering

  Hello world
  
  I have a bunch of data from AMFPHP to be edited by flex. The data is a combination of data is is attached to various SQL tables. The format is similar to:
  
  < date = October 10, 2008 ">"
  ... < grade_number rank = "1" >
  ... < name of the subject 'English' = >
  ... < name type = 'homework' >
  ... < input id = "1" >
  ... < entry_e > create new homework < / entry_e >
  ... < date > 10/10/2008 < / date >
  ... < object > 10/10/2008 < / topic >
  ... < Adder > 1 < / Adder >
  ... < / Entry >
  ...
  
  I used to send these data on an object, and then use a collection of grouping and a filter function to extract relevant data when an opportunity chose the date, subject, category, type. This barely worked and given with the binding problems. I feel, the best solution is to use an EX4 object instead. To do this, however, I need the following information:
  -A list of all possible values for each grade, subject, date and type. These values would then fill controls to choose fields to filter data to allow the user to drill down to the entry they wish to change.
  
  I'm on the right track with this idea? How do you get a single list of all possible values, you can filter the dataset? It is d ' assign focus in the books about how to filter data with an e4x expression, but little discussion of how to get all possiblve values so that the filter (for example to fill a combo box that lists the possible values)
  
  In addition, when the data is returned via an e4x expression, is a copy or a pointer to the source data? IE, if I change the data returned, does it also change it in the source data?
  
  Thank you

  I don't know how your application is designed, but does a good job up front in the design data exchange will save you tons of time/bandwidth later.

  In my application, there are semi-static data, driven by the table (for example, tables search db). These data do not change frequently (for example, possible to assign grades a student 'A, B, C, D, F').

  Then, the user starts the questioning of the system (for example, the list of students in a course). In the query result, the information may be changed (for example, assign a student a grade from the menu drop-down). Once all changes have been made, a 'Save' may be issued. A 'Cancel' might pull down new data (i.e., re-run the last query) and reset the visible screen to a non-altered state.

  Quote:
  So from what I understand you query the PB often enough?

  Not really. The initial list of data loading can be slow... but we did things like caching server-side to speed up a bit. This initial list of data is retrieved only ONCE per logon session.

  Queries are short and return summary of results. The entire record of the data extraction is fast enough because things are indexed on the back-end.

  Quote:
  I tried to limit the bandwidth by downloading a copy of the week and then classes allowing the user to "save changes". I'm not too worried about getting a data collision since the classes are unique to each connection.

  Looks like your application protocol design is simple. The user logs and data are extracted by user id. The user updates the data and record visits. Fact.

  In this scenario, if I'm right about your application, I would always break cela in two different HttpService calls to get a sort of simultaneous treatment. A HttpService would be responsible for downloading the data to fill in the boxes on the menu drop down. The other to download the classes for that day there.

  In fact, this raises the question; the user can update the other than just the current day? If so, looks like you will need to allow the user to choose a day, extract the data for this date, allow updates/save, then choose another day to update.

  In this scenario, the separation of the HttpServices is paying off, since the query to extract semi-static data to fill drop-down list boxes is done only once when the user connects to the departure.

  Again, I'm not sure the design of your application, so I talk only through different scenarios.

  Quote:
  Therefore, there is no way to obtain the unique values of the dataset object directly?

  I'm not sure that understand this issue. You would get the values to fill your combo boxes through a HttpService (for semi-static data). It can then return something like:

  Then you might have something like:

  I hope this helps.

• (bb10) Problem with the long description on my apps on BB world

  Hello!

  I don't know why but all my apps seem to have lost "long descriptions" what bb10 Blackberry World poster.

  Everything is right on the Playbook, but not on Z10.

  I'm doing something wrong?

  

  It is a known problem. It affects anyone who makes your app is installed. If you uninstall one of the apps, you will see the description back up to what install you it again.

  BlackBerry is aware of the issue. They said nothing about when it will be actually fixed.
