Flex :: Modules Over MXML Component Architecture?
Dec 2, 2010
I 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?

There are lots of examples of how to create skinnable components in AS3 using the new Spark component architecture, however I've yet to find any such examples using MXML.What I'm mainly referring to is defining the skin parts and skin states. It seems as though the SkinPart metadata is supposed to be associated with properties and as such can't be used in MXML, is this correct?

I'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?

eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )

The IDs for all tags in an MXML component, no matter how deeply nested they are, generate public variables of the component being defined. As a result, all id properties must be unique within a document. This also means that if you specified an ID for a component instance, you can access that component from anywhere in the application: from functions, external class files, imported ActionScript files, or inline scripts.
Which is fine if your application is all contained within one MXML, but I'm having trouble referencing IDs of components within Modules, and then inside ViewStacks/Navigation Containers within a given Module.
If I can reference a module with FlexGlobals.topLevelApplication.myModule, shouldn't I be able to reference a Panel called myModulePanel with the following?

The application is too big to describe here, but I can tell you I have up to 20 modules or more that the client can use at any time. And if I go on loading screen after screen, my application can ocuppy 500MB and more.The script that I use to load and unload modules is:
public function createModule(modulo:String):void {
if(moduleLoader != null){
moduleLoader.unloadModule();[code]..............

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

How do I say an MXML component is inside some package? Well, it's in a different folder... I know how to do it ActionScript... But when I do in MXML I don't declare the package explicitly because I don't know how, and when I call it to my application, it states that The prefix "package" for element "package:Component" is not bound.

In 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.

I'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?

I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.

Here is an example of a custom component. It is just a box with a title label and a close image (X):
[Code]...
When using the component in an MXML document, I would like to have the "(HEADING TEXT)" replaced with a parameter (should be easy) as well as the "(INSTANCE MXML)" with several labels, text inputs, check boxes, etc. (maybe harder). I have found this script-based method, but I would like a cleaner compile-time solution if one exists.

I have an event, which I have dispatched in my main.mxml:
var evt:UserEvent = new UserEvent(UserEvent.USERINFORMATION);
evt.userVO = storeObject;
this.dispatchEvent(evt);
I can listen for it while in my navigation.mxml file, by using
this.parentApplication.addEventListener(UserEvent.USERINFORMATION, onInfo);
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.
the second component is in a viewstack in navigation.
