Is there a way to access the DOM-Elements of a mxml file in a way that you can in JS (e.g. using Prototype or jQuery)?
I need to know if a top-level element has a child (sub-sub-...-childs) with a certain id.
In JS (using prototype) it would be something like:
$('tabs').select('[id="something"]');
If I Have an XML variable that equals this:
var X:XML=XML("<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" xmlns:ns1="Tools.*" minWidth="684" minHeight="484" creationComplete="Init();" xmlns:ns3="Components.*" initialize="I()"/>");
And I try to list the attributes via:
var AList:XMList=X.attributes();
The three namespaces, "xmlns:mx","xmlns:ns1", and "xmlns:ns3" aren't listed among the attributes! How can I access this information programmatically?
I'm working on a simple task/calendar tool where tasks can be added dynamically to a canvas. Here is the main application as defined in Main.mxml, which is essentially just a Canvas and a button for adding a task:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Canvas id="MainCanvas" borderStyle="solid" width="300" height="300">
[Code].....
The problem is that when I add a Task instance to the Canvas, the children (the button and label) don't appear. I tried setting creationPolicy="all" on both the Canvas and the BorderContainer, but it still didn't work. I've read a bunch of posts about people having issues accessing members of their class before the class is fully loading, but all I want to do is SEE that Label and Button show up inside the BorderContainer.
I have two mxml files. one is main that is application tag mxml file and another is my mxml component file. I have a viewstack in my main mxml whose id is, say, "mainViewStack". Now I want to set selectedChild property of "mainViewStack" from my mxml component file. [code]...

Does anyone know if its possible to access children elements in a SWC? I have created some MC's and inside of some of these MC's I have some dynamic textFields. I export the content to a SWC and load it into my Flex project. No problem loading it or accessing the parent elements, they display fine. But I want to access the textfields nestes in the MC's and modify the text. When I debug the app, I can see the textfields as child elements. It's typed as a TextField and the Instance Name is the same as input in the Flash IDE but I cannot access it. When Flex compiles it throws an error saying it doesn't recognize the method. I've tried to insert actionscript on the timeline, linked external classes and nothing can be accessed.

I have extended an mxml component with an actionscript class. I'm trying to access a component in the mxml file using the id (in order to add an event listener) but I cant seem to do it.
I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I've got an object declared and instantiated in my Flex application's singular MXML file: public var CDN:CDNClass = new CDNClass; I would like to access this same CDN object (and its public methods and properties) in another class declared in a separate .as file as such:
[Code]...
But when I try to access the public method parsePlayList in the CDN object in a method in the class defined in the .as file, I get the following error: Access of undefined property CDN The reason I want to do this is to break up the logic of my application into multiple AS files and have minimal MXML files, probably only one.
There's an HTML technique known as innerHTML that allows Javascript to add/delete/edit HTML elements. Can actionscript do something similar to MXML?
For example, my main application's mxml part is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Button x="29" y="347" label="Button"/>
</mx:Application>
But after running an actionscript code, I want the user to see the result of:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Button x="29" y="347" label="Button"/>
<mx:RichTextEditor x="183" y="24" title="Title">
</mx:RichTextEditor>
</mx:Application>
Is this possible with Actionscript inside a MXML file? p.s: is this possible with Degrafa library elements?
Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?

How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

View 2 RepliesI've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

This is a project I'm working on for a simple demo tutorial application in Flex. I am using mxml pages.

How can I dynamically pull the value from the object in the list to load the child mxml file into the container that I have further down in the application?
