Once you load an actionscript page from scratch (in my case loading XML data from a file, initializing various other elements in a fairly time consuming way) if you navigate away from that page and then return to it, (via the browser 'back' key for example) is their a way to forego the previous initialization and just immediately bring up the previous Actionscript page in its fully initialized state.
View 2 RepliesI've got a component written for my app by a third party developer and am trying to integrate it, but I've found a bug that seems like it's either a compiler bug, or there's something with how Flex and static variables work that I wasn't aware of.Basically, I have this:
public class ModeChangeController {
public static const DISPLAY_MODE:String = "DisplayMode";
}[code]...
If I use //V2 (i.e. comment out V1), a bug occurs at the startup of the application (some TextFields are uneditable and contains no text), but with //V1 and not V2, it works fine. If I comment out both, that also works fine (I don't get the TextField bug).It took me a while to figure out that it was that static const String that was causing the issue, but I'm still not sure why or if there's something I can do about it except for just moving the DISPLAY_MODE to Events (which is what I've done at the moment, but it's not a particularly nice solution).There are no errors in the log. The order of the includes in my BorderContainer code doesn't matter. I've googled for "as3/flex static initialization order" but haven't found anything.
Clarification: showInitialView() never gets called. It doesn't get there before the other bug shows up. Just having the V2 line there causes the problem.
Update: I've fixed my problem with the TextInput strings not showing: Turns out that adding the component caused the Tahoma font to not show up. However, setting the font-weight to bold fixed that problem, or switching to Arial. With that said, the original question still stands, because when I ran it without V2, it found Tahoma with normal font-weight.
to point out some good tutorials on creating applications in flex that are don't have UI's?Actually, it looks like all I really need to know is how to call afunction upon initialization of the flash object. I tried the creationComplete attribute, but it doesn't work in browser.
View 2 RepliesI am loading a component which makes a HTTPService call to get data that will then be used to set certain variables in the component. I make the HTTPService call in an init() function (for the initialization event) and then set the variables according to the data received in the HTTPService result handler. However, the variables are still null at both the initialize stage and at the creationComplete stage. If I try and read the variables in a creationComp() function (for the creationComplete event), those variables are still null. Is this correct?
I guess I don't understand the flex initialization cycle very well. When are those variables actually set and available to be used? I need to manipulate those variables automatically after the component loads. Is there an event that comes after creationComplete that is appropriate or some other way to approach this? I am using Flex 3.

I need to completely initialize a custom component in my Flex app (i.e. I should be able to access it from action script and get its properties and its children etc), But I do not want to add it to the display or make it visible. I have tried to add it to my visible component, but keep it visible, but often many of its properties are set only when it is drawn, so i don't get what i need. Is there a way to add a custom component to some sort of 'Virtual' display, that is not visible to the user?

The jist of what I'd like to know and focus on understanding, is details on how binary deserialization occurs in Flex 3. When is the constructor called, when are properties set, are private members serialized or does all deserialization occur on and through setters, etc? I'm having a hard time finding information on this.In a Flex 3 AIR application, I have a pretty complex object graph(just a bunch of objects referencing one another, kinda like a big data model except a bit more complex) that I serialize to a file using a single call on the FileStream.writeObject and readObject on a root object, which serializes and deserializes the entire object graph.I found that I needed to always have a default constructor, else I would get exceptions on the objects when deserializing if they were part of an ArrayCollection. So I had to eleminate the constructor parameters or set default values. I now have many setters like this in my classes, such as the below where mConnection accumulates some information it needs through different setters, where as before I had this all packed into the constructor since all of the information is really necesary for the Connection to function:[code]So the connection's serverIP is still an empty string because the server was assigned to the client's property before the server was completely initialized.
I could probably resolve this by using binding so that updates to the serverip in the server are bound to the connection, but I find binding properties to be fairly complicated (it's really simple on UI in mxml cause you just use the curly bracket syntax but doing it by code is what I found complicated). I have also resolved some cases by removing the constructor parameters entirely, so that there is no default values. All that aside, I still really need a deeper understanding of the details of binary serialization as far as how it rebuilds the object graph. I even have circular references, and it seems to handle those fine and maintain multiple references without duplicating objects. It's just when my constructors/setters are more complex that I'm running into these problems because of the order of what occurs during deserialization. It is really inconsistent though, as adding breakpoints in various places seems to influence the order that things occur, making it more difficult to debug.On a side note for anyone that might sidetrack the topic because I am serializing a class called Connection. I added some code to address some things, like in the Connection class there is an instance of a Socket. Of course my socket would not be connected after I close and reopen the application and deserialize it, so before I serialize my object graph, I go through and close the socket and set the reference in the Connection class to null, so that there is no longer a reference to the socket and thus it will not get serialized. After deserialization on the next application run I create a new socket.
I am working on a server push from Java to Flex. But some how the MessageBrokerServlet is not getting initialized, seems like it is calling a method from: flex.messaging.config.LoginCommandSettings.setMatch() Eventually I found out that this method indeed does not exist in that class (LoginCommandSettings). I there something else that is going wrong?

View 3 RepliesAssume you have a variety of number or int based variables that you want to be initialized to some default value. But using 0 could be problematic because 0 is meaningful and could have side affects. I have been working in Actionscript lately and have a variety of value objects with optional parameters so for most variables I set null but for numbers or ints I can't use null. An example:
package com.website.app.model.vo {
public class MyValueObject {
public function MyValueObject (
_id:String=null,
_amount:Number=0,
[Code] .....
The difficulty is that using 0 in the above code might be problematic if the value is not ever changed from its initial value. It is easy to detect if a variable has a null value. But detecting 0 may not be so easy because 0 might be a legitimate value. I want to set a default value to make the parameter optional but I also want to later detect in my code if the value was changed from its default without hard to debug side affects. I suppose I could use something like -1 for a value. I suppose it depends on the nature of the variable and the data.
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 work mainly in C++, and at work we use this awesome autonomous singleton pattern where you automatically add statically instantiated classes to some global list. If you're familiar with c++, imagine something ala:
class CuteSingleton : public ISomeInterface
{
*** stuff ***[code]...
So basically, CuteSingleton is instantiated at DLL load time and added to a global list of ISomeInterface interfaces. This is really powerful because it lets us rapidly prototype tons of code without polluting our existing codebase by having to include these prototype files, instantiating classes like CuteSingleton in a big initializer list somewhere, etc.I've been trying to figure out how to do something similar in actionscript for a few days now and I'm coming up empty handed. All I want to do is have this code instantiate this class without having to reference it in some other files:
package EntitySystem
{
public class EntityManager extends AutoGameSystem [code].............
I have two questions.First: I created this class, which supposed to create sort of 3D cube

I'm trying to buid a video player application usin the Youtube API, which is loaded remotely from their servers as described [URL]...reference.html Basically I want to add a playList via XML or flashVars which would be stored in the Model among other data taken from the video feeds of youtube by HTTP request. The issues are:
1.- I don't know where the youtube API would fit in the MVC pattern, because it has two parts, the Loader instance that you can add to the display list and the API Object itself that is more like a controller. My first approach has been to create a controller class which loads it and initiates it. But then I have to provide a reference of the loader to the View. Should I do it using a setter in the view, dispatching an event and then a listener in the view gets this reference from the controller, or including the reference in the model??? I'm a little bit lost here.
2.- On the other side, I don't know how to implement the strategy pattern betwen the view and the controller in this scenario. Should I leave the whole initialization process outside the MVC pattern? It's not that I'm obsesed with design patters, I'm just trying to learn how to use them and put myself this as an exercise: Build a videolist player for youtube so that it's easy to add, let's say Vimeo support later.
i'm trying to build a flash site and ran into a problem... i have a gallery page with a bunch of page numbers at the top. when you click on one, a movieclip loads of some images coming in.so the problem i'm having is that i made a little animation for when you roll the mouse over the page number (they scale up when the mouse is over, scale back when the cursor moves away)... what it's doing is when you roll over, it goes to a certain frame in the timeline and plays that animation.that's all working cool, but i need it to not do that once it's clicked on. so basically when you actually click on a page number, the over script should stop until you go to another page... here's the code i've written,
function over(event:MouseEvent):void {
this.gotoAndPlay(30);}
function out(event:MouseEvent):void {[code].....
So I have a movieclip that I want to play nice with my class file. So I set the linkage and all that and it works. But, my initialization function gets called with no parameters, because I have not set any. How do I do that with this method?
I've tried something like:
Code:
import tab;
tab1_mc = new tab("left", 5, 55, "testclip.swf", 0);
And that sets the parameters, but not before the linkage on the MovieClip fires. how to get the best of both worlds?

I'm loading an f4v into a project, and there seems to be an "initialization" delay. Googling leads me to believe this is a known issue, but I can't seem to find an answer on how to get around it, if even possible. Here's what's happening:
1) AS3 call to load f4v into a VideoPlayer (or FLVPlayback, doesn't matter)
2) All bytes immediately load (because I'm working locally)
3) [15 second delay]
4) Receive READY event and video starts playing
When I use the same exact code, but with an FLV instead, step 3 does not exist.Is there a way around this, which I assume is a "processing" delay for the high quality video format?Or, if not, can I assume that it's a set amount of time each time? Ultimately, all I care about is alerting the user to what the delay is - if I know it's always 10 seconds, I can make a preloader of sorts that lasts exactly that long.
