i am using xmllistcollection for displaying data in list. whenever i run my application data is display in list control, but this warning has displayed in console. How can i remove this warning warning: unable to bind to property 'xmlnode' on class 'XML' (class is not an IEventDispatcher)
View 1 RepliesI am getting the error: warning: unable to bind to property 'Description' on class 'Object' (class is not an IEventDispatcher)
this is only when the data is bound to a List as an ArrayList, though. I had it in a Datagrid before (just as an Array) and it did not cause any issue. I'm not expecting to be able to bind any data back to the class 'object' not even sure which object exactly it's referring to.
My list data-provider is an ArrayList.. populated by a result event from an SQL query contained in another class:
private function loadDayComplete():void
{
var Meals:Array = _day.MealResults;
[Code].....
The day class I have is a data holder to get all the data (from several tables) for a 24 hour span.. I have classes for each individual datatype for editing them. But I'm not sure do I even need to worry about the warning if I don't plan on editing the values? it completely spams the console though whenever I touch anything, so I really would like to get rid of it. I tried an object proxy as I saw described elsewhere but nothing changed. The text is in label fields right now anyway, which can't even be edited.
I've got an object that contains a dozen or so fields I want to bind to form elements, so that I can use that object to send the data back to the server to be saved.

Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.
View 2 RepliesI am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.
For the purposes of replicating this issue with as few lines as possible I have two views, and one presentation model. The code follows.
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
we have following class

If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)
Can't seem to bind to data from within a custom component. I've tried BindUtilis and {} but can't seem to fathom it out. Here's what I've got:
I have a class DataModel which has been made bindable
Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)
When the data within DataModel.somelist is updated the DataGrid reflects the changes but the CustomComponent doesn't appear to.
I was expecting to see the trace (CustomComponent.dataProvider) fired whenever this._dataModel.itemList is changed. [code]...
say that i have a base class called Base, that is Bindable and has a String property like this:
[Bindable]
public class Base
{
public var msg:String;
[Code]......
where msg is some textInput field. I am getting a message from the compiler that....
Data binding will not be able to detect assignments to "msg"
is there a limitation with data binding to a base class?
I'm wondering if there is a way I can bind a flex property to flash property?, the flash property is inside a swc file created in flash with the Flex Component Kit for Flash Professional, I can manipulate the flash component as a regular flex component, but I want to bind their properties, is there a way?

If I have three classes:
public class Example {
public function Example () {

You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {

I was wondering how do you access the stage property from a different class that's not the principal class tied to the fla? Essentially, I have main.as which calls another class menu.as, and I can't seem to be able to use the stage.stageWidth property from menu.as. What's the proper way to be able to use the stage property from any class? Do I have to import it separately each time?

The Main.as file will have all of the game logic, such as the mysteryNumber.
The other actionScript files represent rooms that the user may click and depending on the 'mysteryNumber', it will execute the 1 of 6 scenarios.
So for example, if a user clicks the Library page, the LibPage.as will call the 'mysteryNumber' and execute some code to display on the library page.
It will be the same for the other 4 rooms.
The problem I have is that the LibPage.as won't call the 'theNumber' property from Main.as
Here's the Main.as

package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;

I just recently been using a lot of prototype javascript stuff, and was wondering there was anything like the "bind" method, for use in AS3. It's proved quite useful to be able to look both at the event.target as well as the class object the handler function might be associated with.
View 5 RepliesIn ActionScript 3, there are some classes that will represent a value rather than the class itself. It's hard to explain properly what I mean, so take this example:
[Code]...
I have this class
package somePackage
{
public class SomeClass
[Code]...
I want to be able to get those static property given it's name.
Example:
public static function getProperty(propertyName: String): SomeClass {
//don't know what goes here
}

Im bulding a class that has a bunch of properties, and looks something like this:[code]This compiles fine, but doesn't print anything. When i step through it, it seems to skip over the loop, as if "this" doesn't have any properties.
View 2 RepliesI want to extend the FileReference class of Flex to contain a custom property. I want to do this because AS3 doesn't let me pass arguments to functions through event listeners, which makes me feel sad, so I need this property to exist on the event target, so I can access it.I also want to be able to cast extant FileReference objects to this class without any fuss. I have:var fr:SmxFR = e.target as SmxFR and I want that to work; right now it just returns null.A blank, newly instantiated SmxFR object has the extended property in place, but all of its inherited properties and objects return Error: Error #2037: Functions called in incorrect sequence, or earlier call was unsuccessful.[code]I get living handle property from that, and all other (that is, inherited) properties throw Error #2037.So, maybe what I want to do is going to require overriding FileReferenceList? If the original objects must be instantiated to SxmFR, that's what I'll have to do, since I'm using FRL to allow the user to select multiple files at once. Are you guys sure there is no way to fast from a FileReference to my class?

View 1 RepliesI'm using a library that has a function that returns an instance of some class Engine.

What about AS3 classes am I misunderstanding?
I recently found a method (ByteArray.clear()) that FlexBuilder complains is possibly undefined; however, the method is in fact documented in the Flex LiveDocs. It must have been added in a later version of the SDK than I have installed. I'm not asking about this particular method, but I'm giving it as an example of the documentation issue that I'm trying to resolve. My questions are:
How can I determine what version of the SDK or Flash player that a method or property was added in? How can I tell which versions of the SDK are supported on which Flash player versions?
I want to be able to determine from the documentation, instead of compiler or runtime errors, what SDK and Flash player versions are needed to support newly added methods.
With Java I look for the @since javadoc tag when I need to know this, but I can't find an equivalent feature in the Flex docs.
in AS3, I have an external class ImageLoader, that loads an image upon request. In that class, I have an event handlers:

I am trying to send the download progress updates back to the main Document Class and display it on screen, so I am trying to dispatch the event "PROGRESS_INFO" and then get the information from the passed Event Object, like so: Document Class
[Code]...
This however, is proving futile... any ideas on how I can get the progress info out of the IMageLoader class? note: I know I can add bytesLoaded & bytesTotal to a public variable, but then I won't get the benefit of seeing the bytesLoaded property update in the ProgressEvent class.
Using org.as3commons.reflect I can look-up the class name, and instantiate a class at runtime.I also have (non-working) code which invokes a method. However, I really want to set a property value. I'm not sure if properties are realized as methods internally in Flex.I have a Metadata class which stores 3 pieces of information: name, value, and type (all are strings).I want to be able to loop through an Array of Metadata objects and set the corresponding properties on the instantiated class.[code]I realize that I have to declare a dummy variable of the type I was to instantiate, or use the -inculde compiler directive. An unfortunate drawback of Flex.Also, right now there's code to account for typecasting the value to it's specified type.
