Flex :: Flash Builder - Extending PopUpButton And Using It In A 4 Web Application?
Mar 16, 2012
In my Flex 4.6 web application I use mainly spark components, but there is also an mx-component - a PopUpButton extended by me (the source code is below).Users report problems with that button, but I can't reproduce any - since weeks.
I've tried replacing mx:Menu attached to it by a s:List but it hasn't changed anything. I suspect there is a "null pointer exception" or some other failure, that I don't hit when testing myself...
My question is: why does Flash Builder reports warning about my custom button as if its methods would be private or not present?
My main App.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

I was running my application from Flash Builder 4.5.1 without any issues. (It is a Flex application that connects to .Net Web Services). However, something has changed recently in my configuration or project, because when I try to run the app with the play or debug button, I just get a grey screen. I can't even stop on any breakpoints. Eventually (maybe 30 seconds), a message pops up like so: 'The Flash Builer failed to connect to the running application. Please make sure that you are running the debug version of Flash Player...'

I'm a GIS Analyst that was moved to an Analyst Programmer position. This has been a hard transition for me as I don't have much of a programming background, but I was thrown into it. 'm working on a Flex app inside a jsp page. Essentially it is a grid 3x2 that has images and text. What I am trying to do is have more than one titleWindow reference in this page, so that when an image is clicked a titleWindow is opened. (If anyone has a better idea, especially if it has to do with a hover I am very open to that!) Currently I have it working for one image. However, when I try to add a second function it errors on me. "Error 1021: Duplicate function definition" Below is the entire code for the main page that calls up the titleWindow. The code below is what gives the Error 1021.

I've built a simple application in Flex Builder 3 with some trace() calls. It's an "ActionScript Project", no MXML or AIR involved. I don't run the app from within Eclipse, I just open the generated html file with Firefox.
I'm using the Flash Player 10 Debug version. I've correctly set mm.cnf to log trace output, following the official instructions. A flashlog.txt file is generate in the appropriate location.
Despite all that, trace output is not shown in the log file. What am I doing wrong?
(I suspect it's a compiler option, but I can find no such option in the project options in FlexBuilder)
(If I do run the app from Eclipse, by pressing F11, I can see trace output but only inside Eclipse, not in the log file)

I'm new to developing iOS applications and my school gave me approximately 5 months to develop an iPad application. I have no knowledge or practice on Objective C so since Flash Builder 4.5 allows the development of mobile applications (and I have experiences with Flash Builder), I decided to develop my application on Flash Builder instead.
Everything is going fine until I was told to include a SplitView in my application. I implemented a List on the left side of the application. Clicking on any of the list items will navigate the user to a to another view but i also included and retained the list on the left side of the new view in order to simulate a "SplitView".
Initially it felt as though it will do the job of a SplitView like how it does when I attempted it on XCODE but it doesn't look or feel natural. I found this video which shows that it is possible to create a SplitView on FB but I've cracked my brains and I really can't figure out how it is done.

If I need to call a specific function in the parent application from a child in a flex project, what's the best practice for this? Would it be to dispatch a custom event from the child and have a listener call that function? Or to directly call the function with FlexGlobals.topLevelApplication?

I have a quite different problem with resizing. I have a Flexbook component which uses the middle part of screen (center) with a html header menu and footer. The problem: The scaling works perfectly when we run in the local machine ( Flexbuilder). But when we deploy it to the server its like scaling never existed.. The requirement: when user maximizes the window or minimizes it, the Flexbook should be resized to fit the screen.

I have an air application that loads a swf ( built in flex ) , this swf loads moduls and basicaly my air application is a testing environment for this swf .
when i run it in flex environment ( eclipse ) it runs fine , when i run it from my programs ( as an air program ) it gets stuck , what i was thinking is that it has to do with security issues because it gets stuck when my main swf try to loads the moduls .

I have found some question which refers to my initial question :on xcode Usually resolved in synthesis by :
flushing certificate cache correcting the signing certificate ( using Distribution in replacement of Developper) C checking and correcting the Application ID who was sometimes not the same between the one declared in iTunes Connect and the one in the app.xml file
The fact is that I still has the problem on Flex Builder, which is when I upload my application, it failed with "Application failed codesign verification"
[Code]...
So the question is what could still block the uploading of the application on the App Store?
How to resolve "Application failed codesign verification." when uploading Application, build with Flash Builder 4.6?

When creating an Actionscript Project in Flex builder 3 an application class is automatically created and dropped in the root of your source folder. In my case my source folder is called src/.Is it possible to change the default application class to a class which is not directly in the root of the src folder? It seems when right-clicking on class files which are in sub packages the 'Set as Default Application' option is not selectable.Is this done on purpose by Adobe to enforce all pure AS projects to have their application class residing in the top-most package?

So I have a PopupButton and when I click on the button I want the Menu that pops up to have rounded corners. How would I go about doing this?UPDATE:I found an update similar to what I want to do, it can be found on the following page:The only difference is that I'm showing the Menu with a PopUpButton. So far this is what I have for my custom Menu:
package {

I am trying to programmatically skin a PopUpButton control in Flex Builder, but having no luck. As far as I know this requires writing a custom skin class or creating a modified version the control class itself (since the control is MX and not Spark). Again, just to clarify, I want to programmatically modify the appearance not simply set styling properties or display an image. I've been able to do this programmatically with other MX controls (e.g. tabs in a tab navigator), but not with the PopUpButton.I think part of the problem may be that the control is actually composed of two separate buttons, so you cannot draw just one rectangular area over the whole control.

I am using the Flex PopUpButton & data binding a Menu object to the popup. I successfully added an icon to a menu item; however, it does not look like Menu supports the disabledIcon property common in many other elements for use when enabled: false for that menu item.Is it possible to extend the Flex Menu class to use disabledIcon? Should I use a different type of data binding class?
// create the array collection of menu items
var menuItems:ArrayCollection = new ArrayCollection();
var addWidget:Object = new Object();

I have prepared a simple test case for a PopUpButton opening a TileList with black and red entries and it mostly works, but has 2 annoyances. I've searched a lot, tried several variants (added [Bindable] members in my renderer; added color member to the bids array; created my public override set data() method; ...) and has been getting some answers too, but they are way too general.
1) Scrolling "tl2" right-left doesn't work well: the entries are displayed in a mix of red and black. I know the TileList reuses itemRenderer, but how do I fix the problem?
2) In debug-mode I get numerous warnings: warning: unable to bind to property 'label' on class 'Object' (class is not an IEventDispatcher)

I have prepared a very simple test case to demo my problem.just place the 2 files below into a Flash Builder 4.6 project and they will run instantly.My problem is that the menu attached to my (slightly modified) custom PopUpButton never changes - even though the underlying Array data provider is changed when you click one of the 3 buttons on the right side of it:
AuxButtonTest.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application [code].....
I've commented my custom event out - it doesn't matter here.click at the buttons few times and then look at the menu - it always has 5 items and that is wrong.
AuxButtonText.mxml:
<?xml version="1.0" encoding="utf-8"?>

Few users of my Flex 4.6 web application are complaining, that the mx.controls.PopUpButton at the right bottom corner of it sometimes opens a List underneath it and is thus unusable (I can't reproduce that myself - probably an unlucky combination of their Flash player and/or font size setting?)
How could I ensure, that the popUp component (in my case it is a spark.components.List) always opens above the PopUpButton?
I suspect, that I should create a skin based on mx.skins.halo.PopUpButtonSkin and assign it to my PopUpButton? And I probably should use the PopUpPosition.ABOVE constant together with the PopUpAnchor?
I have prepared a screenshot and a simple Text.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"

I still can't reproduce the bug myself, my users aren't very helpful (mostly older folks, playing my card game). I've searched in Adobe JIRA, but couldn't find such a bug.
I wonder, if there is a way to short-circuit that method to enforce opening the popUp above the PopUpButton.
Or if I should put the _list into some container...

Does anyone know if there is a way to make the new Package Explorer window in Flash Builder emulate Flex Builders 'Flex navigator' window?
Bottom line is I don't always need to peer into SWC's, and I don't like having a 'default package' automatically created for me. Not sure why the interface wasn't made simpler, allowing access to more power and complexity only if necessary. I want to focus on the code, not on how to navigate and use the bells and whistles in the coding environment.

I just upgraded to Flash Builder 4 (beta 2) from Flex Builder 3 which I have been using since it came out. Problem: All the projects that were in my workspace from Flex Builder 3 did not carry over into Flash Builder 4 (e.g. in the "Flex Navigator" view if FB3). Flash Builder 4 now uses the .FXP format to manage projects, but Flex Builder 3 did not. Is there an easy way to get all my projects back into Flash Builder 4?
