I have started learning flex 4 and I got myself thinking about how to change views. So I have a question what do people usually use - states or views (ViewStack). The type of web application I am making, can use both, but what do developers use in big projects or maybe they use non of the mentioned before?[code]...Best view architecture in it?
View 1 RepliesI'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.
View 1 RepliesI have a mobile application that I want to try and reorganize so that it's easier to read and update and follows better practice.I want to implement an MVC pattern, but I'm getting a little tripped up on getting there. I'm just hoping for some help with rebuilding the architecture. Here's the outline of my application:
Level1) MainView has a column of 5 buttons that when clicked lead to View1, View2, View3, View4 or View5.
Level2) Each of these views is the same: a list, but each is populated with different data. Selecting an item brings the user to another set of views SubView1 - 20. that each are again populated with a list.
Level3) However, any selection made on a List in a SubView leads to a view that is always the same for all selection paths - but is populated with different data. Basically a button, another list, a text input and a textarea.
From what I gather, I should be able to use a lot less files and achieve something of the same result:The model being a single class for data? The controller being a class or that controls the business logic, and a view that calls the controller?
I've got a Flex 3 website. I set-up adBrite in an iFrame to serve ads, and it works fine. I've got 2 ad zones in 2 iFrames. My problem is that as Flex has a "pageless" architecture, I only get credit for one hit even if the user clicks every button on the site. In short, I get one pageview instead of several. adBrite said that if I can figure out a way to refresh the ads when the user selects a new item in my navigation menu, they're cool with it. They suggested just refreshing the whole app.
View 1 RepliesI have one .mxml file (the Application) with a ViewStack (with 4 views) and a ControlBard, obviously I can change the views with it, but what I want to do is: in view #1 I have an image which I want to convert to a "hyperlink", so when I click it I go to View #2, is this doable? Also I would like to pass somehow some data (like a String) to that View #2 (lets say the it's a user avatar I click so I want to go to the second view which will show me his profile, that's why I need his name/id).
View 1 RepliesMy problem is that when I try to pass an object from the navigator.pushView(view, dataobject), I can't figure out how to access the dataobject from actionscript. I can access {dataobject.property} from MXML easily, but I want to set a variable in the new view to the passed dataobjects property.
View 1 RepliesI 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?
I'm asked about Display List architecture in Flex at an interview.
View 2 RepliesI developing an AIR application in Flex that would be dealing with playing different SWFs. I am finding some issues as these SWFs that I am playing are heavy. I find that the animation is not smooth and is causing the graph of CPU usage to go high (my be because single thread architecture of Flex). I am therefore planning to have a multi process architecture for my application. Something like Google Chrome. I have one main application as one process and other SWFs would be playing in separate process but should be seen inside the main application window. How to make it possible in Flex?

View 4 RepliesMy 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.
how to incorporate FileReference method like Upload into a Cairngorm architecture.Specifically, I would think to fire an event with the File in it, and that's fine. But how would one then be able to listen for e.g. Progress Events?One thing I thought is to have the delegate fire off progress events that are listened for in the View.
View 1 Replieshow would the 3-tier architecture be applied in a Rich Internet Application?I thougt that flex was presentation, .net web services where busines and informix was data. But then when I started I feel that I must be wrong.
View 1 RepliesI started a project a while back using the following architecture from Adobe Developer Article talking about Creating marketing platforms in Flex. I did my first set of coding locally forgetting that my server did not handle Tomcat. So I said okay, and cut some corners and then some other limitation came up and I cut some more corners. Eventually for a good week or two, it was trying to get the project working with making the ends meet. Layers started to merge.
In the end I used a
PureMVC (Presentation/Client) -> ZendAMF (Communication) -> MySql (Data) Layout.
It worked but I never felt as though I had some layer just to take care of all the SQL calls to the data.It just felt hacked together
So should I keep the above setup and just start from the presentation layer and move downwards like they said in the article or is there a better layering (based on a hosting plan that does not handle Java) I could accomplish ?
UPDATE: My current hosting plan - [URL]
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?
View 1 RepliesI have creating a distributed note taking application in flex, it basically is a notepad I can keep in my desktop tray. When I add notes and goes back to a server and saves it in a database.
To am struggling to design the application correctly, I want to have a Syncing service that polls the webserver for changes and updates an Array of Note objects. The problem is that my note corresponds mxml component, aka SingleNote component. There are four different cases when being, a. a note is updated from the server poll, in that case I want to singlenote to update the settings b. a note is added to the array from the server, in that case a new SingleNote needs to be created c. a SingleNote is added from client, in that case a Note is added to array, and sent back to server d. a SingleNote is change from client, in that case the Note is updated in the array and sent back to server
The properties are SingleNote(Width, X, Y, Text).
I'm about to have to write a web page/app that will serve the agenda for circa 100 people on a page. One line per person, one column per day with 3 clickable zones in each cell. In HTML, the page is way complex for the browser to load quick and there is no possibility to click on a border between 2 cells to for example split an event that spreads among several cells. So I search an not too overkilling technology to render this kind of view. I begun with a PHP generated HTML page but the number of elements in the page make the mouse move jerky.
Moving to JAVA would give me better performances regarding the reuse of the generator of the view but it will still be an HTML page. So, here is my question: do you think that going forward with JAVA and its graphical capability is the simple solution or is Flash a better option for this part of a Web App? I'm afraid of the code I'll have to write in JAVA to handle the GUI presentation as well as the events generated by the 1000's cells plus borders of the page. In Flash, the graphical part seems simpler even if the actions handling is still huge.
I am wondering how to make a 360º view bubble, like they use for Google Street View, but have no idea how to go at accomplishing this task... i have the string of photos that i attached in photoshop(so that if you connected the left to the right it would be a full 360º view).
View 1 RepliesThere is a Flex app with 7 main views. And there is a memory issue when navigating between views.All these views were in a ViewStack, but due to some involving 3D objects I assumed it was too much to have it all in the display list. I'm now clearing all children from the stack and adding/removing them when needed. This gave a small performance increase, but still becomes unresponsive with use. The strange thing is, with this and the original method, the CPU climbs with use but eventually levels out somewhere. Now I'm creating new instances of each screen when they are navigated to and setting the previous variable to null. Now it looks like CPU is spiking when the view is created, but leveling out to something much much lower than it was. This felt like progress, but now the available memory keeps climbing where it wasn't before....
My understanding was calling remove child or remove all children would mark the object for deletion when the garbage collector next ran. I can't see any other references to the instance. My code is along the lines of [code]I have a function for each button to add a new instance like the above.The only thing I can see and feel silly asking but need confirmation, is each view extends a class called "Screen", this class contains a singleton reference to some core components.[code]Would this trick the garbage collector into thinking it was still needed? General advice on clearing Objects from the memory pool would awesome!!! I've never needed to analyze the Flash Player in such depth.I think it's an error with sound drivers, removing all sound and shes purring like a kitten. Works on my machine fine with windows XP, but not on the touch pad the application is crashing on with windows 7 (unsure of the drivers looking into them now) Now I'm thinking its not the drivers, tried 3 different versions, all with no improvement. I did discover the sound was fading in and out with the TweenLite lib. Doesn't look like there are any memory leaks in TweenLite as it works fine on other machines. Just the use of volumeEasingFunction seems to consume increasing amounts of CPU until it freaks out. It is crappy hardware running windows 7, which doesn't help.

in flash, I encounted a source file that is cropped and I cannot move it, is there some sort of cropped view in flash I dont know about? I cannot find anyinformation about it, it has rulers displayed as far as I remember.
Basically you cannot move in the file to edit anything viewpoint wise, everything outside of the movie area is invisible and not there? As if cropped.

We used to write our UnitTests with FlexUnit and we were just testing our model. Now we want to test the view too. Before i run my tests i create an instance of my view and my model to test the stuff. When i try to access the view i get a null pointer exception. If i add the view to the displaylist it somehow works - even if i remove it from the list right after adding.it looks something like this:
var myView: MyView = new myView();
//myView.initialize(); will throw error
