Yet another woe with the AdvancedDataGrid - this time, with the AdvancedDataGridEvent. It seems that when listening to the ITEM_EDIT_END event, several of the event properties are returned null. I've been getting null for event.column, event.item, etc.
View 2 RepliesI've written the following custom component, SubNavBar.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" height="100" width="300"
creationComplete="init()">
<mx:Script>
[Code]...
Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?
I have got problem accessing a property of a component. I want to use this property to decide whether to include a particular child component.
For example:

Now AnotherView.mxml has a property

I have an Flex-Object with for example 3 properties.
myObj.prop1
myObj.prop2
myObj.prop3
I like to generate 3 Comboboxes to show the data.
No problem if I do it hardcoded in sourcecode.
But how can I find the prop1 to prop3 at runtime?
If next time I have 5 properties with different name it should generate 5 combos.

I have a Flash Builder application which uses URLs within its code and I want to be able to change these URL values without having to recompile my application, i.e. I want to have a plain text file I can edit which is used to populate these URL values when the application begins. I've worked out what feels like a kludge to do this with ResourceBundles, but maybe there's a better or more straightforward way to go about this.

How can I programmatically click the browser's Back button from within my Flex application. I'm using deep linking to allow the user to navigate back/forth inside my application. I want this to work when BACKSPACE is clicked inside the application as well, but Flex captures BACKSPACE and the browser doesn't get the event. I don't want to implement browsing history myself within the application, naturally. Can I send BACKSPACE to the containing browser?

Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances.

View 9 Repliesthe script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
'null' is null or not an object
try { document.getElementById("").SetReturnValue(__flash__toXML(function() { return document.location.hostname; }()) ); } catch (e) { document.getElementById("").SetReturnValue("<undefined/>"); }
but this is from flash script and i dont have control over it. it just say JScript - script block.

Over the past three weeks, I have lost at least 120 man hours because of some lesser known functionality in ActionScript 3. One of the problems was that, with Internet Explorer, if there are too many messages sent through LocalConnections, it will slow the messages sent through, but in the standalone player and in Firefox, this threshold is significantly higher. Another was that the static values of a class are instantiated even if the member itself is not being used:[code]Since FooClass had a static reference to a Singleton, that Singleton was instantiated so when I loaded a Module which used that Singleton, it would bind to values in an unpredictable way.Additional cases where things behave in an unexpected way:
So here's the question (and I'm sorry for omitting this in the original post), is there any consolidated documentation for this type of behavior anywhere? Is there any (even non-Adobe) documentation on these issues (websites, forums, books, ANYTHING)? I know that these things are definitely easy enough TO document, but has anyone done so?
Is there some library for flex, that will let me: define properties to fully exclude from serialization define classes to serialize without the property names (as if they were an array)
View 1 RepliesIn regards to as3 project: Is there a way to inherit the properties of a given DisplayObject? I am looking for a single method that will grab something like the x, y, width, height, color, etc. Whatever is involved in the common classes between the two display objects.
Edit:
I don't think I was clear enough... Let me give an example of the type of functionality I am looking for.
var sp1:Sprite = new Sprite();
sp1.x = 30;
sp1.y = 30;
sp1.width = 500;
sp1.height = 30;
var tf1:TextField = new TextField();
tf1.inheritTransform(sp1);
So, in this case I know that the method 'inheritTransform()' doesn't exist, but I am wondering if there is something similar. Or maybe I am missing the point of extending a class in some way? I don't see how the two would relate in such a case.
I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea
if(theRect == undefined){
Alert.show("creating");
var theRect:Rect = new Rect();[code].............
but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?
I have a simple AS3 class that just holds private variables. Each private variable has a getter function, but not all of them have setter functions. At runtime, Is there a way of telling which properties do not have setters but are read-only? Then I can decide to give the user an input field to edit the properties that have setters.

Just been playing around with the tutorials, on the Set properties/Get properties. Everything is all cool, except the "instance name" aspect. I dnt really understand that too well. Is it possible to change an Mc Name dynamically? If you look at my FLA when you hit the top left red button you will get a trace of the mcName as "square". Now if you input a new mc Name on the right hand side, you will see it change on the left hand side. But i want to know why it doesnt remain as the new mc Name, it still goes back to square.
View 3 RepliesI forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?
Here is the code that I thought of, even though it doesn't work
var a:Object = new Object();
a.bproperty = 0; //lowerlevel properties
a.cproperty = 1; // lowerlevel properties
[Code].....
This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project.

I recently added Flex SDK 3.2 to the list of compilers in my Flex Builder installation. (I know I am working with kind of outdated SDKs :( ). Ok, so when I changed the SDK version to 3.2 for an existing project, I couldn't find the properties buttonMode, useHandCursor. And the Filter classes like GlowFilter and DropShadowFilter were not available. I was able to use them once I switched back to SDK 3.0.
