Flash :: Flex4 Host Component Have The Same Function As A View Mediator/helper?
Jul 17, 2011
Coming from Robotlegs/PureMVC, I am pretty familiar with the concept of the view mediator, i.e. a component that pretty much listens to events/requests coming from the "dummy" view and makes a further request, sends an application-wide signal/event, executes a command, etc, based on the request from the view. Can the host component idea introduced in Flex 4 be considered a the same as a mediator? The only thing that slightly bothers me is that host components are still considered views, because they extend SkinnableComponent or any of the classes that further inherit from it. In my view, the mediator should be completely left out of view logic.
Nevertheless, I do not want to write a skin, a host component, and a view mediator for that host component, because that would be quite an overhead, and would lead to more complexity rather than abstraction.Should I use host components as mediators, and put application-level logic there, for instance application level event dispatching?

I have one question about pureMvc. I use pureMvc to build an engine, in the engine init part i have an requirement
1) moduleA must init firt
2) moduleB , moduleC need init after moduleA init complate.
3) moduleD need init after moduleB & moduleC init complate.
4) moduleA , moduleB , moduleC , moduleD all extends Proxy beacuse the four system all need to send notifiation ,but no need to listen it.
But to fit for the requirement I can't use command to do it, because they have ini order and also they need to remember current state(ex: moudelB is init Complate but moudleC is not init complete then can't init moudleD) but command is stateless. The best way I think is use one Mediator to do it, beacuse it can both listen and send notification. My question is :
1) Is this a good way to use one Mediator to do it?
2) If use Mediator is good way, then when it hear first moduleA is init complate
registerCommand(FIRST_MODULE_INIT_COMPLATE , initStepTwoCommand);
sendNotification(FIRST_MODULE_INIT_COMPLATE);
removeCommand(FIRST_MODULE_INIT_COMPLATE);
Need to do things like that way or just do the inti logic in the Mediator?

I've got a very simple project in FlashBuilder 4.5. It's a mobile application of type ViewNavigatorApplication with a single view, MapView. In the MapView.mxml file, I've got a Flex component of type Map declared in xml.
[Code]...
In this same project, I've an actionscript class called UserGeolocation. In this class, I'm attempting to get a reference to this map component. So far, I can get a reference to the top-level application, its ViewNavigator and the NavigationStack of said ViewNavigator. However, I cannot find a way to access the MapView, much less the map I've declared within it.
I'm aware of methods like firstView() and activeView(), but I want an absolute solution, one that retrieves the view regardless of whether or not it's first or active. I've tried navigator.getChildByName("MapView") with no luck.

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

When using BasicLayout (i.e. absolute positioning) - what is the best approach to place a Flex component in the center of the application?In the test case below I'm using x="{width/2}" but this gives me at least 2 problems:How do I account for the component dimensions (the ProgressBar in the test case)?Is the binding {width/2} a good idea to use? Wouldn't it send unnecessary DATA_CHANGE events in some cases?And finally I wonder, how this all applies to full screen applications using StageScaleMode.SHOW_ALL - because currently my application is aligned to the top-left in the full screen mode and there is a white dead zone on the right of it. (Which is at least a change from pure Flash/AS3 behaviour, where the full screen content is displayed in the center of the screen and 2 dead zones on the left and right).[code]

however, on the line where i call s3upload.init, i get a 1195 error saying "1195: Attempted access of inaccessible method init through a reference with static type S3Uploader."When i looked up this error, it seems like almost everyone getting this was trying to call a function with set or get. However, I am not doing this and i have no idea why i am getting this error.

I'm using the Alert.show in a function and I want to get the user answer from there. So how can I achieve this. The problem is the function that call Alert.show will return a true or false value depend the user answer.but It seem that in Alert.show it only allow to pass in a CloseHandler for this. that is a new function. and since that I can get the user answer from where it is call to return the user answer.

I have a Flex component that is a view of a data Object that recursively has a reference to itself.
For example if you had an Employee class that references a boss field of type Person, I'd like to nest the same view for that Boss. This shouldn't be an infinite recursive relationship (e.g. I'd only be viewing the boss field of each object).
I've tried creating an MXML component that references itself but when I run it locks up (seems like it gets into a recursive loop).
Is there anything you can do like includeInLayout conditions that will make sure it doesn't even instantiate that component.

I have lots of child text inputs within a spark Scroller. How can I make the TextInput with id of "x" come into focus if I have a..z id's, also for the scrollbar to scroll automatically to that child item? I can use x.setFocus(), but the scrollbar doesn't automatically scroll to that item? why?
<s:Scroller id="scroller" width="100%" height="100">

I'm experiencing some strange text rendering behavior in the Spark RichEditableText component.
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
[Code] .....
The above application simply navigates through the five sentences in the DATA array (every time the Next button is pressed). For whatever reason, RichEditableText component doesn't completely reset its view (by clearing the previous text) before setting new content. From what I can gather, this faulty rendering is somehow based on the combination of line count and relative width. I also discovered that if I set the width property of the RichEditableText component to an absolute value (say, 100) as opposed to relative (percentage, 100%) the text is rendered correctly. As far as I can see, this behavior is unintended and is, in fact, a bug.

I'm building a mobile AIR app using Flash Builder 4.5. The initial view in my views package is TestHomeView.mxml. I want to refer to it in one of my .as classes elsewhere in the app, and I'm not sure how to do that.
Theoretically I should be able to add an "id" attribute to TestHomeView.mxml, but FB gives me an error: "id is not allowed on the root tag of a component". The root tag is s:view.
The reason I need to do this is that within another class I make various calculations and then need to pass an array of values to a component in my view class. So in SomeOtherActionScriptClass.as I first assemble the array, myArray, and then in that class I want to do this:
myViewComponent.viewArray = myArray;
If I'm going to do that, I also need to import the view class into the .as class, which strikes me as weird. So is there a simple way to do what I want, or do I have to dispatch a custom event which contains the array, and listen for it in the view class?
EDIT - Based on the below MVC suggestion I did the following in model:
[Bindable]
public class Model
{
private static var myModel:Model;//doesn't let me name it 'model' because
[code].....
But it is coming back null. It isn't null when I put a breakpoint in the Model class, but when I try to access it from the view class, it's null. The model itself isn't null, but that variable is.

I'm currently building a Flex 4.5 mobile project including several views and custom written MXML components that can be incorporated dynamically into those views.How do I determine which component currently has focus, namely has been activated by the user tapping on it? The background for this is a global search function in the main application. Depending on the results of this search, fields in the custom components are set. Given that I don't want all components in a view to listen to the outcome of that search function, I have to check which one is currently active.I'm trying to bind the selected object (the result from the search function) to the active component.

Do you know how if you drag an <mx:Label> or <s:Label> component into your Flex project, when you go to design mode you get this panel on the right to set its properties like text etc.
I have a custom component that I can call with actionscript, or with mxml like this:
<comps:TheComp field1="OK" field2="Yes" />
The component takes this input and uses it for its internal operation
[Code]...
When I go to design mode, I can see the component under custom components, I can drag it to the stage and see it, but can't set its values field1 and field visually on the right like a normal <s:Label> or <mx:Label> would have. how I can add that? Do I need to make it inherit something or anything else
