ActionScript 3.0 :: RIA For Handling Objects Across Components?
Feb 10, 2010
I'm used to building web apps using proper architectures, but relatively new to the RIA space.One of the issues in rich client app is approaches to handling communication across components. (I've played around using the EventBroker concept.)In a recent Flex3/AS app I was looking at they took an approach that seemed to work pretty well, but I wonder about the drawbacks (or any other pros)...They took the concept of having a singleton object that would hold objects that could be used obviously from any components within the app by a simple call to...
var myAppModel:AppModel = AppModel.getInstance();
You thus could put any objects in there that you wanted access to from different components. It seemed to serve as the equivalent of a "Session" in the JEE space. I'm not so sure from an OO perspective it's the best thing to do, but it did seem to work pretty well.

I'm building an application, where objects are attached on a canvas and the tree of that canvas is held on a tree component. Each time that i attach an object the tree adds a new child etc. I want to do this on the other way around.. I want to press a tree node and "communicate" with the specific object, so that i can change its color, delete it etc. I've tried some things but nothing happens!This is my code:
var working_space:XML = new XML();
working_space.addTreeNode("Canvas",0);
myTree.dataProvider = working_space;

I have been trying to fix my collision handling for hours now, but it seems like I am running in circles. To be blunt, my collision handling sucks. It is easy to break, and hardly works on complex objects(like water in my case, see the test at megaswf . com / serve / 1577272)
For collision detection I am using the collision detection kit, or CDK.My level is made up of different large MCs, such as a "wall" MC containing all of the smaller walls, such as water, a tree, or a wall. CDK allows me to hittest the single walls by hittesting the large one, and not each one individually, making it easier for myself.My code has a lot of repetition(8 directional movement), so I will put a "//..." to simplify.

public class Main extends MovieClip[code]......
I have literally been working on this all day, and only feel like I'm making it worse every time I change something. You don't have to spoon-feed me code, the idea should be enough...

I've posted my question on other forum but without success so I couraged myself to ask here too. I've got an application (see image) which consists mainly from two different components. It is media player similar to winamp or so. Two main components are MainPanel and second one Playlist. These contain several other components so MainPanel constains Buttons objects TimeCounter or TrackDescriptionWidnow etc. and Playlist contains AlbumNext AlbumPrev buttons, Display which holds Textfields with names of tracks. So the thing which is most complicated is actually communicatig between some objects. Let's say I click on the track in the Playlist. In fact many objects need data when other one changes its state. When I click NextTrackButton in MainPanel, next songName displayed in the Playlist needs to shine, or if the ShuffleButton is pressed one of the random song will be played. My question is how to communicate between objects that are not in the propagation scope when events occur For example if some object fire an event in the playlist(Component2) only objects that come from Stage through Engine can listen for that event. So objects in MainPanel can not hear dispatched event. I've got many events, many objects listening for some of them, and I ended up with the total mess who is listening for. I register events to my class by public static const EVENT_NAME; and then dispatch it on that occured situtation. I managed to add some events listener to Engine and set bubbling to true, this way Engine can listen for most of the events, but then I have to dispatc new event to the other component to make it listening. Do you know how to communicate properly between differently scoped objects?

Here is what I'm trying to do. I have some TextArea objects inside a HGroup, created in the mxml part. I want them to have an id of an element of a bidimensional Array, a matrix. I'm having problems declaring the TextArea objects as Array components. I've tried a lot of formats and google it, but I found nothing relevant.

I'm writing a Flex application using Flash Builder 4 and I'm having a bit of trouble with an AS3 object.Essentially, it is a BorderContainer, with a few buttons and images, and programming logic that determines how these interact with eachother and a database.
What I want to be able to do is configure the layout/style of the inner components using MXML and CSS. I can configure the inherited objects, but not ones that I have defined.[code]...

I am pretty new to flex, specially to mxml part. There are some confusing things for me.[code]...
So question is how do I access that button's properties. I want when something happens in Xyz file, button's (someId) visibility to become false. If Abc.mxml was AS class file then it would be easy, just make object etc., but how to get if it's mxml file.

How do you communicate an error to the web service consumer ?
For example, my web service has a function to insert employee into db.Suppose while inserting the data , the database gave an error,what should be the best way to inform the user about the error.
One way is to depict it through the return value of the web service method but what to do when the function is supposed to return a complex object like employee when there is no error ,and will send an error string when there is an error ?

I have a problem with event handling. I'm working on a calendar, on which events can be listed. With actionscript i loop through an XML file with the days (and if there, the events for that day). So far so good. Where it goes wrong is this: I only want to display blocks with the day numbers on it. When you click on a day, a box pops up and shows the event's for that day.
This is what i did: created a movieclip with classname mc. loop trough the xml file and for each day create a new instance of mc with the day number as text on it. This al works, but now i want to add an eventhandler for each day. How to do this?

If I have a graphic that is fully transparent in places, can I make only the non-transparent portions of the graphic respond to mouse clicks? I realize I can probably do this with a few lines of code, e.g. detect the click and then check the alpha value under the mouse. But I was looking for something simple. For example, in Director there is an "alphaThreshold" in a graphic that determines at what alpha value a bitmap will respond to mouse clicks. Does Flash / AS3 have a similar capability?

I'd like to arrange things so that I have a chain of keyboard event handlers in my flex application, all of whom are queried when key down events occur. Basically, when a visual component is on screen, it is a candidate for handling a key press event. Something like this (clearly this is pseudocode):
<application handles_keys="F5, F6">
<tabGroup>
<tab1 handles_keys="pgup, pgdn">
<control handles_keys="0,1,2,3,4,5,6,7,8,9" />
[code]...
I have a class written that will respond to the key events the way I want it to, so how do I register one or more instances of this class to have the results I want? Also, note that there are some situations where this class should receive events that would ordinarily be handled by a UI component. The TAB key is the main example; I have a few cases where I want my key down event handler to fire even when the focus is on a text field.

We have a Flex client and a server that is using the Spring/Blazeds project. After the user logs in and is authenticated, the spring security layer sends a redirect to a new URL which is where our main application is located. However, within the flex client, I'm currently using HTTPService for the initial request and I get the redirected page sent back to me in its entirety. How can I just get the URL so that I can use navigatetourl to get where the app to go where it needs to?

I am building a Flex application using Pure MVC pattern and Zend framework for calling php code on the server. I need to sync some data with my server which is using MySQL as the database. And there are 5 such tables I need to sync. So I call these php functions at regular intervals from Flex and use long polling on php side. The client side code for my subjects lies in 5 different proxies.
Should I send 5 separate requests from each proxy to call the php code which is lying in separate classes. Or should I build a separate proxy to send 1 request from 1 php file and then distribute this data among different proxies on the client side. Which one will be more effecient? Mathematics shows using separate proxies and php classes allow more number of users to be accomodated on the server.Can I write 1 SQL command to fetch data from all 5 tables given they cant be joined on any column?

I have a very simple Flash movie with multiple keyframes. Each keyframe has buttons which I'll be attaching event listeners.
I was hoping that I could add all event listeners to all buttons in all keyframes by using a document class. This works for buttons in frame #1, but anything else gets a null reference exception:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I also tried adding a layer to the timeline that spans all keyframes and putting in the eventlisteners (and respective addEventListeners) there. Same thing - null reference exceptions for everything not in frame #1.

Have been dabbling with flash for few years, but would like to send data to external PHP file and would like flash to process response.The way I have it working is to register function for the submit button on the main stage where I have the form instance. However, when I do this, it stops rollover effects from working on submit button. (The button is actually a movie clip instead of straight forward button btw.)

I have a class with a XML object in it. In one of the class' methods, I tell the XML object to load a document. Before I do that, I set up the onLoad event to call one of the class' other methods. The problem is that in that handler function, I can't seem to access any of my class' data. If I try to use the "this" pointer, I'm getting the XML object not my class.
A simple example:
