• Issue in Flex application with J2EE capabilities

  Characteristics of the environment:
  Eclipse: 3.2.2
  MyEclipse: 5.5.1
  Flex plugin version: 3.0 (Beta 3.0) + LCD 2.5.1
  JBoss 4.0.1
  
  I followed steps are:
  1 created flex project (in which I used mx:OLAPDatagrid)
  2. features of web-project added to it.
  3 deploy in Jboss
  
  After deployment, his error showing as: "could not resolve < mx:OLAPDatagrid > the components."
  
  Can someone help me please in this issue.
  
  Thanks in advance

  Hello

  The OLAPDatagrid component is available only in the version of Flex Builder Professional. For the first problem, the one where you build a Flex + LCDS 2.5.1 project, the answer is that LCDs 2.5.1 do not include component OLAPDatagrid and that means you have found errors on the duration.

  For the second problem, the one where you try to use the compiler for J2EE module, the answer is that the compiler J2EE module supports only the components that come by default with flex sdk.

  Thank you

• Complex issue of Flex application design

  I'm new to Flex and just started working on a retail online store application.
  However, I came across a problem and I'm stuck.
  
  Here is the structure of my application:
  I have an application file - Main.mxml and
  two modules - LoginModule.mxml & MainModule.mxml files
  and I load the module LoginModule.mxml by default and after a successful login, load MainModule.mxml
  
  
  The MainModule.mxml has a sample of flexstore similar viewstack
  and contains the elements of the view - Home.mxml
  Products.MXML
  ... etc.
  The Products.mxml's filter section, product catalog, shopping cart Panel
  (similar to ProductsView.mxml in the flexstore sample).
  
  Here's the question:
  Whenever I click on a control (checkbox, combobox.. etc) in the filter Panel
  I get an error message, as shown below:
  
  The box can be found here:
  TypeError: Error #1009: cannot access a property or method of a null object reference.
  at mx.managers::PopUpManager$/addPopUp()
  at mx.controls::Alert$/show()
  at mbzprodsView::ProductCatalogPanel/filter()

  For Combobox, click:
  TypeError: Error #1009: cannot access a property or method of a null object reference.
  at mx.managers::PopUpManager$/addPopUp()
  at mx.controls::ComboBox/::getDropdown()

  to mx.controls::Button / http://www.adobe.com/2006/flex/mx/internal::buttonPressed()
  at mx.controls::Button/mx.controls:Button::mouseDownHandler()
  
  However, the MainModule.mxml file works OK if I convert this component in a file of the Application of the Module.
  
  Not sure if it is a limitation of Flex 2 or I need to organize files in a different way.
  
  Any help will be greatly appreciated.
  
  Thank you very much

  Found the solution in Michael Ritchie's Blog. Thank you Michael. I lost two weeks of my time on this issue.

  Included the code below in the script of my application file block and it solved the problem:

  
  Import mx.managers.DragManager;
  Import mx.managers.PopUpManager;

  public var dm:DragManager;
  public var pm: PopUpManager;

• universal support iOS and CSA 2.0. It will affect Flex Mobile projects?

  Hello

  Regarding the latest release notes for AIR 16, it says

  "The legacy compiler is not (and will not) compatible with iOS 64-bit." [...] It will be removed with the 16 of the AIR SDK version"

  I'm a little lost with what it means for Flex Mobile (4.6 or Apache Flex SDK). We will always be able to compile once AIR 16 is released or this new compiler will be the issue with Flex compiled for iOS projects? Must make us changes on existing applications in Flex?

  Thanks for your clarification,

  Fabien

  It seems that this evil is rumor spreading around... a lot of people don't bother research properly.

  When they talk about the legacy compiler, they speak of the ADT, MXMLC will continue to work. Simplified IPA packaging process is: Source code - MXMLC / ASC2---> SWF - ADT AOT compiler---> IPA

  So with AIR 16 ADT -useLegacyAOT argument is removed.

• Flex iOS app refuses to connect to a self-signed SSL server: error 2032

  Hello everyone, thank you for reading this and I hope you could help me with this problem.

  I'll cut to the Chase. I am currently working on a mobile app in Flex for Android and iOS and the app has to get a few HTTP requests and retrieve information from a server, which is currently developing a teammate.

  Everything had to be working very well until we decided a few days before when we have integrated a SSL self-signed certificate in order to make connections more secure, etc.

  On the side of the app, this change, lying just to replace the http with https url and it seems to work perfectly, or that's what we thought.

  Tests on the Simulator or on an Android device worked well, he just showed the warning provided access to a server that had a rogue certificate that could be ignored without any problem. But when we tried to test a Release on a camera of the iPhone version, it would not just work more. A connection every time trying to be established with the server, error 2032 flash is triggered and it fails miserably does not display not warning about certificates not approved at all. For me, it's really confusing that it works on Android devices, but not on the iPhone device.

  I searched on the Web for people having the same problem but I couldn't find an answer to this specific issue of Flex-iOS-Self-signature-SSL. I found this post unanswered questions: http://forums.adobe.com/message/3359072#3359072 but nothing much.

  I tried to create a crossdomain.xml file on the server with guaranteed set to false, and some other stuff to avoid crossdomain policies, but it changed nothing and the problem persists.

  I'm really out of clues, sort of desperate and have no idea how fix it. If anyone knows something related to this problem, please, help me, I'll be less grateful.

  Thank you!

  We decided to buy a verified SSL certificate, and it worked. We can say that the problem is solved, but it wasn't actually because the connection must be established and that the invited user to accept or decline the self-signed certificate, not only do not make the connection.

• Re: Flex automation and license

  I realize that it is probably a problem of Flash Builder, rather than an issue of Flex. This is perhaps why there is no answers in the Flex forum.

  I have a volume license for CS5.5 Master Collection at my University that I just installed. 

  Everything works fine except when I go to FlexMonkey allows for automation testing, which I did for a long time in Flex 4. After about 20 actions through automation, I get the message ' don't buy not present.» With the free trial only limited records are allowed. "This isn't typo on the word version of Pouvez me change that ;-)

  In any case, I did everything suggested in this thread: http://forums.adobe.com/thread/834214.

  I certainly have installed Premium - suggestion of Deepa I network monitor and the other totally fine features. To make sure any remaining files are around, I totally uninstalled CS5.5, deleted all the folders under Program Files Adobe, deleted the licenses.properties file in C:\ ProgramData\Adobe\Flex, emptied the trash, bought for my lunch of computer and still no luck. I started test operation and after 20 items, I get the same message: license does not exist. With the free trial only limited records are allowed. Is it possible that the Premium volume license versions do not properly activate the Automation API?

  I spent about 2 hours of frustration with four people about technical support. Very frustrating. Finally told that technical support does not support Flash Builder, only "consumer products" and I'll have to pay for the care of level 2 support. It just seems strange that I can not get the product to turn on properly and that I have to pay for technical support. , But three out of the 4 told me that after they hit impasses on the question and the fourth one I transferred to volume licensing sales, who said: oh, you can probably guess what says. What? The fourth person did tell me before transferring this volume license does not require the same type of activation so that he thinks that it does not properly activate Office Tools. Just his humble opinion.

  Anyone know better?

  Hi John,.

  Sorry to let you know that the automation is allowed only when using FB Premium or Premium FBPHP licenses.

  No other licenses are considered valid, and there is a bug on our part.

  We are looking at this and http://bugs.adobe.com/jira/browse/SDK-30752 is registered for this track.

• Flipped BitmapImage in Flex 4.1 (possible bug)

  Hello everyone.

  I feel the strange behavior of BitmapImage component Flex 4.1 (more specifically - build 4.1.0.16076). Here's an example application that causes a question to ask:

  < s:Application creationComplete = "this_creationCompleteHandler (event)" >
  < fx:Script >
  <! [CDATA]
  Import components.base.viewport.Viewport;
  Import mx.events.FlexEvent;
  Import spark.components.Group.
  Import spark.primitives.BitmapImage;
  
  [Embed (source = "image.jpg")]
  private var imageClass: Class;
  
  protected function this_creationCompleteHandler(event:FlexEvent):void
  {
  var container: Group = new Group();
  var image: BitmapImage = new BitmapImage();
  image.source = imageClass;
  container.addElement (image);
  addElement (container);
  }
  []] >
  < / fx:Script >
  < / s:Application >

  The problem is that the image is flipped horizontally (and do not). This probably has something to do with the bug SDK-26346, which is now closed. In the comments, I found a 'solution' to the question: If change us places the last two lines of the method this_creationCompleteHandler() (we add the container to the display list and only after that we add images to this container) the problem goes away. But I have to say that version 4.0 of the framework does not suffer from this problem. Moreover, it also does not apply for other components with 4.1 as well (I guess there could be a few others, the origin of the problem, but I tested with BitmapImage only).

  So here's my question. It is illegal to add BitmapImage container agreement, adding that the container of the display list (and Yes, that means we need to create children of any component only in the method createChildren() () and not, for example, in a constructor)? If this is true, then why add an image to a container, before he was added to the display list worked without any problems until the new version of the framework has been realeased? Or is this a bug of lance by the function "layout mirroring" in version 4.1 of Flex? In this case, I have to report a bug.

  Thanks in advance,

  Michael

  This looks like a bug to me.  I have reproduced the issue in Flex 4.1 and Yes, it looks like a regression in 4.0.

  Please fill a bug report and view the ID of the bug on this thread so that we can continue the investigation.

• GETTING PATH ABSOLUTE IN FLEX

  Hello
  
  I am facing 2 issues in Flex...
  (1) I'm not able to import flash.fileSystem in my MXML Application
  
  (2) is it possible to get the path of the file using fileReference. I want that the path of the selected file
  
  Can someone please!
  
  
  

  There is no way that Flash Player opens a local file for you. Remember that the Flash Player has been designed and developed for web application - soft drinks that are served with the intention to keep the data on a server remotely. If you want to download your image on a server, it is fine.

  If you want to store the files locally, please look in Adobe Apollo. You will always get use Flex and Flex Builder. The result will be a desktop app with an easy to use, operating system independent, way to read and write local files.

• Keyboard CODE for X 201?

  Hello

  Some time ago there are three different suppliers of keyboards for ThinkPads and you may change if you like one better than the other. Is it still possible to get a NMB keyboard if I buy an X 201? Or are there other suppliers of these days?

  See you soon!

  Dag

  NMB and Chicony are the only suppliers of keyboard to the X20x series.

  Search for parts

  By clicking on the link above and seizes the series and type of machine you have, you will be able to know what keyboard you get.

  NMB (T 42, 3671)
  Chicony (42T 3737)

  While NMB is supposed to be the best overall, it seems that there are flex problems with them in the X20x series. A little research in these forums will tell you, but I don't know if the issues of flex on NMB keyboards has been fixed.

• AIR 4 SDK and asdoc

  Lose myself just too much time to understand how the hell to get the AIR 4 sdk asdoc to work.

  The lack of documentation, the instructions from Adobe becomes overwhelming. It is just unbelivable how a company can release a product without any documentation or such.

  Even if there are solutions, example and others, they are still distributed on some blogs... but in this case, as everyone is does not have an information hostage.

  Yes, now my freggin question, how to configure the ASDOC on mac in Flash builder!

  first when you point external tool on asdoc, im getting the error:

  use: path dirname

  use: path dirname

  Error: Cannot access c /... /lib/Legacy/ASDoc.jar

  Then I change the patch in the file asdoc an absolute... and im getting:

  use: path dirname

  use: path dirname

  Error: This Java instance does not support a 32-bit JAVA virtual machine.

  Please install the version you want.

  Seriously, the 32-bit on mac, what type of defect is who? ARGHHHH

  can I change the version you want, 64 and now this...

  use: path dirname

  use: path dirname

  Adobe ASDoc

  The 4.6.0 version build 23201

  Copyright (c) 2004-2011 Adobe Systems, Inc. ensamr Med? TT.

  defaults: error: can't open ' /... /frameworks/Flex-config.Xml.

  It's all simply amazing. Why can't there be some decent instructions provided by the supplier which explains what it takes.

  So I found a solution that works for now, yet there should be instructions available officially from Adobe, instead of letting developers to spend hours, days or what ever to find solutions...

  I suppose there may be a better solution, but I did what I could from my little experience with files, executables and flash builder...

  in the asdoc file I put comment out the scripthome and added the static variable instead, the changes are underlined:

  SCRIPT_HOME = "/ Applications/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK/bin/.

  If ["x$ {FALCON_HOME}" = "x"]

  then

  #SCRIPT_HOME = ' dirname $0'.

  FALCON_HOME = ${SCRIPT_HOME} /...

  on the other

  echo base code using Falcon: $FALCON_HOME

  FI

  If ["x$ {FLEX_HOME}" = "x"]

  then

  #SCRIPT_HOME = ' dirname $0'.

  FLEX_HOME = ${SCRIPT_HOME} /...

  on the other

  echo using Flex SDK: $FLEX_HOME

  FI

  That solved the issue of flex - config.Xml.

  Then, when I ran again the external tool, I got error about not finding local sv_SE.

  so in regional frameworks/AIRSDK/settings , I had no sv_SE, solution that worked was to make a copy of the file en_US and rename sv_SE.

  And since im trying asdoc AIR, ext tool should have of cource external libs added both in the arguments field:

  -external-library-path = "/ Applications/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK/frameworks/libs/air/airg lobal.swc.

  Hope that this help others in some way.

  I was getting the same RTE, the same pattern in Flex with passing session even line twice in the argsArray to recreateTextLine method of debugging.

  I came with cases of relatively simple test that consists only of 2 files, I just joined the project in Flash Builder FXP file the related issue of Flex bugs in JIRA: https://bugs.adobe.com/jira/browse/SDK-25826

  This bug is reproduced by a ToolTip displayed in Flash Player 10.1 which

  • try to display 2 or more lines of text;
  •   FTE is used to display text (classmx.core.UIFTETextField );
  • define htmlText to instead of the text in the textfield property to display the error message.

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

  Some possible experience for this TENS I learned during my research:

  1. Line 245, SimpleCompose.as

  workingLine.initialize(_curParaElement, outerTargetWidth,

• TabBar Style help needed

  Hello
  
  I'm trying to understand how a style such as the selected tab tab bar will have the text in a different color than the unselected tabs.
  
  Imagine 4 tabs. 3 are very light grey with black text. 1 is selected and it is dark blue with white text.
  
  I've been everywhere in the documentation and I can not just know how to do this.
  
  Here is what I tried that did not work:
  
  {.myTabs}
  tabHeight:30;
  tabStyleName: "myTab";
  }
  
  {.myTab}
  fillAlphas:1, 1;

  Color: #000000;
  borderColor: #A7A7A7;
  backgroundColor: #6B86B6;

• Flex structural issues

  Hello

  I am in the planning stage of a new project and am not an expert in flex (I plan a consultant), but I try to understand if Flex is the right tool for the job.

  Basically, the system consists of 5 modules, each with 10 to 20 questions. Each question consists of a streaming video and then a multiple choice question. The system must track the results of each question and then write the result in the database at the end of the module. Is Flex the right tool for this? Second, I want to be able to add/edit new issues and/or videos easily - what is the best way to structure this (you don't need to be too specific, I just plan it)? I guess that I would have some sort of XML file external that contains questions and a reference to the relevant .swf or .flv video file and another file maps the questions about the modules - makes it his right? I guess that the SWF, flv and xml files would all work with a php script allowing to save results to the database for logged in users? Any help or advice on the structure of this would be much appreciated :-)

  I also understand, Flex can exit projects for either web or use offline (via AIR (I think), but if we create a full application based on the web with flex, including an interface with a Mysql database, can we then export an offline version too, without creating new things? Sorry if this is a stupid question, I'm a beginner an intention to hire an expert Flex if we decide to go with it.

  Thanks for your help,

  Dave

  Flex is an excellent choice for this system.

  Regarding the best way to structure the application, you alluded with modules, and this would be the way to go. You could an XML file so that it contains the questions, or you can store the data of the question in the database as well.
