Flex :: MXML Component Life Cycle?
Apr 6, 2010I am confused with how component life cycle goes when component build in MXML. and if MXML calls methods automatically then how to call any method in life cycle explicitly.

View 2 RepliesFlex :: Life Cycle Used By Flex Application?
Dec 14, 2009Driven on by curiosity, I'm trying to understand the Life Cycle used by Flex Application. I've done a little research on this argument; the two key concepts used into the FlashPlayer are:
SWF Frame: it's the logical unit that contains graphical code and as code Flash Player Frame: it's the time interval used by Flash runtime to update the screen and defined by frameRate property
If so, could you explain me the relationship bewteen these two concepts? In particular, are they paired togheter or not? The main rule is: the Flash Player streams in a swf; until a full SWF Frame is read, the Flash Player cannot render it.
I'll try to explain what I need to understand. For the sake of simplicity, suppose you have a two frame application: SWF FR 1 and SWF FR 2.
In general (for example in CS4) a frame is considered as a logical unit (delimited by ShowFrame tag) where you can attach as3 code. This as a simplified version of a swf file, i think:
Header // frameRate is defined here
Symbols, classes etc... // this is FR1
=== ShowFrame ===
Symbols, classes etc... // this is FR2
If you have two frame, FR1 and FR2, Flash starts executing FR1 and goes to the next one (FR2). If you don't stop the excution, the Player executes and renderes code contained into FR1 and FR2 through an infinite loop. On the contrary, when you stop the execution, for example in FR2, the flash player loops executing code contained in FR2.

ActionScript 3.0 :: Movie Clip Instance Life Cycle During Class Between?
Nov 2, 2010Nice to be back to this forum again. I need to know if instances of the movieclip, that is "classically tweened" are reused between keyframes, or are they recreated (reinstantiated). Thus may I rely on the fact, that only the properties of one single instance change during the classic tween, or are new instances created on entering keyframes?
My little experiments on that show that the bad variant is happening (instances are recreated), but maybe I misunderstand or misuse something? here is the link to the file which made me doubt (CS4). In the last frame of the animation all previously saved references to the instance are saved abnd compared in pairs. Not all of them are equal and sometimes event some are null.[URL]...
Flex :: Extending Mxml Component With From Another Mxml Component With Visual Child Supported?
May 18, 2011I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

Flex :: Modules Over MXML Component Architecture?
Dec 2, 2010I am actually in the process of Architectural of our project. We have choosen Mate framework. The project is not so quite complex, but what advantages i would get over MXML when i choose Modules.
Main App - > Views - > Events - > Maps - > Services [PHP or Java]
When i come up with Modules based Architecture, it seems to be good but i doubt it should not end up with tight coupling and unwanted issues which may break the head later to solve.
Main APP - > Modules - > Module Interface -> Events - > Maps - > Services
[PHP or Java]
What advantages i do get if i choose Modules over MXML Component? What is the prefered and the best way to Architect an FlexApplication? Since the Application is going to communicate with Backend, do we need to make the frontend more complex?
Flex :: Opening A New Tab And Adding An Mxml Component To It?
Feb 12, 2011In our flex application we have tabs at the main level and under it we have subview.e.g
Home / Tasks / Admin etc...
In one condition we have to click on a button and open a new tab, on this tab we have to add an existing mxml component and show it in the tab.We are using parsley as the framework. Inside the mxml component test.mxml(that is shown in the tab) i am configuring it with parsley using the tag.Now when i add the instance of this test.mxml i am getting an exception. I am deriving this test.mxml instance using teh parsley context
as
context.getObject(id of component) as DisplayObject and adding it to the tabNavigator...
But i am getting exception when i try to grab an instance of a view using parsley context. How do i get an instance of a view or component that is configure through parsley using the parslye context.Also the problem is occuring becuase of the view injection..because i get a parsley excepiton on startup of the application stating that there is some problem in the context.

View 1 RepliesFlex :: Use A Base For A Custom MXML Component?
Aug 26, 2011I'm using several custom MXML components in my Flex 4.5 application.They all use absolute coordinates to place Image, Label, Line, etc. components and are currently based on a spark.components.BorderContainer:
<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer
xmlns:fx="http://ns.adobe.com/mxml/2009" [code]....
Then I've realized, that I probably don't have to use BorderContainer, because I don't draw/need any borders around my custom components.But I don't know, what to take instead of it.I've tried taking <mx:UIComponent> (and removing <s:Layout> tag above), but then I get the error:
'Image' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.
'Label' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.
Is there some simplest possible spark "container"? And do I need a "container" at all if I use (and want to use) absolute coordinates?

Mar 9, 2011I have an event, which I have dispatched in my main.mxml:

this.dispatchEvent(evt);
I can listen for it while in my navigation.mxml file, by using

But in other component, I can not listen for it, even trying the same as I did in navigation.mxml.
tracing it back gives me an undefined.
