I was implementing the positioning via UIComponent.move, which i realized was the wrong approach. After just setting the x and y properties, i did some research and stumbled across the ILayoutElement and its methods like setLayoutBoundsPosition and corresponding methods to modify the skin's display list. But somehow the group, which contains the children, does not propagate its new size up to its parent. I use the updateComplete event to invalidate the group's size and force the layout to be calculated properly a last time. The view looks as expected. But i don't think that invalidating a component a last time after an updateComplete event was dispatched is wrong. Now, what is the right approach for the following task: implementing a skinnable component and a corresponding skin. The skin creates the skin parts in MXML in a Group (id=contentGroup) but the layout is calculated within the skin's updateDisplayList method. I only found one useful article on the web, which is not really a lot of information at all (http://www.adobe.com/devnet/flex/articles/spark_layouts_print.html).

Re: [flexcoders] Modify Flex ComboBox DataProvider
hi Alex,
Prior to SDK 4, is there a build after 3.5?
Thanks for this info. I can't seem to get the way out of this and it dawned on
me now that it must have been a bug.
Thank you.

In the change event of my checkbox, I have defined:
private function checkBox1_change( e:Event) :void

comboBox1.dataProvi der = xmllcAll;

the data for the xmllcAll variable. The comboBox does not get the proper

the values that appear on the list those that were in the the proper

[flexcoders] Using Flex with server that does authentication
Hi all, I'm building a Flex client for a fully-authenticated server with a REST-like API. All communication with the server will be over SSL/TLS. All requests must be authenticated. What I've discovered, by Googling and by trying my own code, is that Flex makes things very, very difficult for such a client. The problems all center around the fact that my Basic Auth headers get removed. The only way I've found to get my headers over to the server is by: - Switching from using HTTPService to URLLoader (the former seems to strip all headers, no matter what) - Changing all my GET's to POST's (because headers are always stripped from GET requests) - Adding a dummy body to my POST's so that they don't get turned back into GET's (why, for God's sake?) and have their headers stripped. I also need to upload files --with authentication. Headers are stripped from FileReference.upload() calls also. I'm aware of this bug: https://bugs.adobe.com/jira/browse/FP-1044 It appears that a fix is in the works, which is encouraging, but it completely baffles me that this issue has been ignored for so very long. I also need to display images in my client that are served by my server --with authentication. I have have mx:Image elements with source properties bound to URL's that point to my server. I know of no way to turn these implicit GET requests into POSTs and to then somehow insert my authentication header into them. At this point I'm really feeling beaten down by how difficult this all is. Does nobody else write clients for authenticated servers? This seems so basic. I've been a fan of Flex for years, but this is causing me to question whether it's ready for real-world RIA's. I'm now considering something desperate like trying to write a Tomcat filter that looks for credentials in a URL parameter and manufactures an Authentication header. I don't know Tomcat well, so I'm not sure whether filters can run before authentication is done. If that works, though, I can go back to using my GET requests and solve my problems with upload and image rendering. The fact that we use SSL/TLS would save us here, since the URL parameters containing the credentials would be encrypted along with everything else. Somebody please tell me that I'm missing something obvious. Thanks much
[flexcoders] Setting preferences on the browser in the release folder
Hello All, I am trying to set up my browser in the bin-debug folder to scroll properly when I set a specific width and height to my swf file but Flex will overwrite it every time with defaults setting.

[flexcoders] ListCollectionMap
Hi guys!
I wanna share a thing I coded recently: it is a ListCollectionMap class, that
adds map functionality to ListCollectionView sort and filter. A lot of
times I felt I was missing something like this, especially when using Mate
framework where everything is controlled by flows of binding events.
ListCollectionMap can do one-to-one and one-to-many mappings and can be used in
data binding chains along with ListCollectionView.
The quick example is:
public var dataIntegers:ArrayCollection = new ArrayCollection([1, 2, 3]);
public var mapIntegers:ListCollectionMap = new
ListCollectionMap(incrementMapping, dataIntegers);
public function incrementMapping(i:int):int
{
return i + 1
}
Detailed explanation and examples are in my blog:

[flexcoders] Re: Setting preferences on the browser in the release folder
I don't know how to override the settings, but I'll tell you what I do to handle this. After I have compiled the release build for the first time, I do a save-as on the html file that was created. I save the copy as index.html, since that is what I typically use (it simplifies the url, as you probably know: if I put an index.html file in a folder 'bla' at the sight 'boo.com', its url is simply 'boo.com/bla' [unless someone has changed the server settings]). Then I adjust the index.html file, giving it the title I want and resizing the flash movie if I need to, adding metadata and so on, and save it. That's the file I post to wherever I am putting the project, along with the other generated files in the bin/release folder. When you do another 'export release build', FlashBuilder ignores index.html, so you don't have a problem with it being overwritten. I hope that helps.

[flexcoders] Re: dispatchEvent import
Hi Marco,
That does look like a problem. The dispatchEvent() method is available
for any UIComponent subclass or any class that extends EventDispatcher.
So, if you're going to use [Bindable] properties in the presentation
model, you would want to have the PM extend EventDispatcher:
import flash.events.EventDispatcher;
public class UserPresentationModel extends EventDispatcher
{
private var _currentState : String;
[Bindable( currentStateChanged )]
public function get currentState() : String
{
return _currentState;
}
public function set currentState( state : String ) : void
{
_currentState = state;
dispatchEvent( new Event( currentStateChanged ) );
}
}
This will allow you to bind the property to a view.
For events that you want to [Mediate], you would use the injected
dispatcher:
[Dispatcher]
public var dispatcher:IEventDispatcher;
dispatcher.dispatchEvent( new Event( myEvent ) );

Re: [flexcoders] ListCollectionMap
Cool, really, thanks for sharing. Although I didn't like the idea of extending Proxy... I think the bug where the dataProvider is accessed in a dataProvider[i] way should've been fixed now... There are also couple of wrong assumption that ListCollection makes when treating data as Arrays, thus not using interfaces. But that's definitely an edge case.

[flexcoders] excluding symbols from sub swf
In my main swf, I have a (CS4) library item with the class of Dog. It's just a movie clip with a picture of a dog inside it. In the sub swf, there is a also a dog on the stage. It's necessary that the item in the sub swf be in the library or components panel, because my designer likes dogs. He likes to place them on the stage, rotate them, and play with them all day. It's a big Dog. And there are many sub swfs. Is there a way to exclude Dog from the sub swfs? Runtime Shared Libraries is not an option--too flaky. And runtime loading of assets is not an option either, unless it can be made compatible with WYSIWYG. I tried this: 1. Creating a dog.swc component, using it, and then putting it in the external library path of the sub swf. 2. Putting the dog swc in the folder with main.fla. These did not work. The big Dog remained either way. I looked into this: Using -load-externs and -link-report compiler options for an actionscript project. But there is not link report for .flas, and no compiler options either, and jsfl does not seem to provide workarounds. Is it even possible (without using Runtime Shared Libraries) to exclude symbols from compiled flas? Thanks! Matt
