Flex :: Swiz Mandates Weak Encapsulation?
Feb 4, 2010
I just started using Swiz, and, it seems like Swiz forces you to create classes with weak encapsulation. Swiz requires all event handlers to be public in order to mediate events.
Assume that component 'A' dispatches a few events, which I want to listen to in component 'B'. Traditionally, I'll just add event listeners on 'A' in 'B' and all the event handlers in 'B' can be kept private. However, if, I am using Swiz, I need to make all the handlers, mediating events, public.

My company is building a Flex application that we may need to port to other platforms:
[Code]...
Currently, I'm looking into application frameworks to build upon and I'm torn between pureMVC and Swiz. I LOVE swiz for its simplicity and how it just gives you a way to hook things up and then apply your own patterns. From a flex-only perspective, this is my 1st choice. But, PureMVC is platform-independent and has already been ported over to most of the platforms that are mentioned above. How valuable is this portability? Will it really make our lives significantly easier when it comes to porting and developing/maintaining multiple applications? If so, then it seems like PureMVC is the way to go.
Alternatively, since Silverlight has the most definite business case for porting of our application, maybe we could port Swiz to Silverlight? I'm not too familiar with which AS3 language and Flex framework features Swiz depends on and whether they are available in C#/Silvelright.

I'm trying to implement a popup window (NativeWindowType.UTILITY) in an AIR 2.7 application that uses Swiz for dependency injection.I have followed the Swiz guidelines that I've been able to find, and implemented ISwizAware on the class that creates the window, and I am calling _swiz.registerWindow() before opening the window, and dependency injection works fine on the window itself after this.
However, the problem I am running into is that I have a child view within that window, and I have a mediator that uses the [ViewAdded] and [ViewRemoved] tags. Neither the view added nor view removed functions are triggering. I'm thinking the issue is either:
The child view is not correctly registering with Swiz.The swiz instance doesn't know about the beans (I have tried manually adding the bean however, which didn't have any effect).The ViewAdded and ViewRemoved metadata tags simply aren't working because each NativeWindow object has its own stage instance.

Since my application is getting bigger, I decided to fragment my project into several modules, but the documentation from Swiz on Modules is very poor [URL]. I tried out the Swiz Examples [URL] but I couldn't inject any data into my module or even catch an event. The module is loaded properly however.
Ideally I will end up having multiple Flex-Projects, each containing one module and each .swf file is deployed into the application deploy folder. However if you aren't familiar with a structure like that, but instead you know how to inject data/event mediating into a module inside the same Flex project.

Figuring out Public, Private, Internal, Protected for every variable in even a basic banner is a lot for me to figure out. Defining permissions of movieclips is totally new to me. Personally, I could truly care-a-less as I don't build apps. I work in smaller media. But I need to do things right for stuff to work fast when clients want changes every 5 minutes.What's good to use starting out so I don't trip all over myself with errors?Is there a general rule of thumb for a least path of resistance? I'm thinking I should just make everything public (or what I used to know as global) unless something "bad" happens.

As I understand it if I set the weak reference param to true in my event listeners I don't need to worry about removing the listeners. I'm not really clear what would cause the listener to be set for garbage collection. I would hate to have a situation where the listener was removed before I wanted it to.

The default value for weakReference in the call to addEventListener() is false. Many memory issues can be resolved by using weakReferences; in fact, some industry experts "strongly recommend always using weak references with listeners".If this is the case, can someone provide me with a good reason why weakReference defaults to true? (Note that I'm not asking why someone would ever want a listener that is not a weakReference, but rather why weakReference=false is the default)

As I currently understand, if an event listener is added to an object with useWeakReference set to true, then it is eligible for garbage collection and will be removed if and when the garbage collection does a sweep.
public function myCustomSpriteClass() //constructor {
this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownListener, false, 0, true);
this.addEventListener(MouseEvent.MOUSE_UP, mouseUpListener, false, 0, true);
}
In this case, is it not appropriate to initialize an object with weak references event listeners, incase the garbage collector does activate a sweep removing the objects event listeners since they were added during initialization of the object? In this case, would it only be appropriate to create a type of deallocate() method which removes the event listeners before the object is nullified?

I understand how weak references work, but I am bit confused regarding it's use in actionscript event listeners. Consider the example below:
public class Rectangle extends MovieClip {
public function Rectangle() {
var screen:Shape=new Shape();
[code]...
If the Rectangle object has no other references, then it is a candidate for garbage collection, but since there is an event listener within the object, the event dispatcher holds a reference to the object, even though there are no other references to the object(other than the one held by the event listener). Hence it is prevented from being garbage collected. Is this the reason why weak event listeners are prescribed? Is the flash player so naive that, it cannot figure out that the event listener is defined within the same object?

So there I was, creating a small app that allowed user to upload custom images. Everything went smooth, until......<insert horror music here> So you want to validate that its an image, and not something else. Well you restrict it with the File filter...but there are ways around that. So as a double check, you check the file type after a file is selected. <drum roll>
Awesome, the type method returns null if the image doesnt have the proper headers....what the hell....So most images are compressed for smaller file size, thus the headers are stripped out. So...Type method appears to be useless....There was a simple way around this using the name method..but what the hell...type method is weak!!

I've been teaching myself actionscript 3 over the past month or so and recently ran into an issue where an object kept doing things after I thought it had been removed. I figured out that the problem was caused by an event listener using the default of useWeakReference = false and I'm wondering why that's the default. what is the advantage to not using a weak reference? and why is that the default? it seems to me that in general you'd want to use weak references, so I must be missing something.

My problem is basically as follows. There is an instance of a class extending EventDispatcher. Everything goes well when I add event listener to the object like this:
[Code]...
Now someFunction is not called even though the line containing dispatchEvent('eventName') is being executed just like before (and there is an external reference to myObject as well). The application I'm developing is quite complex so, unfortunately, I can't post the exact code.

I have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes to the destination in Flex, the time request can be of up to 3 seconds.

I am trying to access html files protected by basic authentication. Below is the code to do that but I still get the authentication dialog. I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog.
Is there a way to add authorization header to the subsequent requests as well?

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.
