Flex :: Performance - Why Does Use A Single Threaded Model

Jul 10, 2009

Over the past few weeks I have been building a prototype application using a Flex front end connected to a J2EE backend using blazeDS. The prototype is an experiment to learn flex and see what its suitability is for a complex trading application requiring a large number of dynamic updates (i.e > 20 a second) via a pub sub type model. During some lightweight performance tests it's become apparent that I need to use multiple threads to ensure the UI remains stable when receiving a large number of updates from the server. All was going well until I discovered that flex has a single threaded programming model!

From a quick Google it looks as though there are numerous hacks to implement thread like behavior. I am sure many people must have been faced with a similar problem. Can people let me know: Are there any good threading libs that are well maintained etc Do other RIA technologies such as silverlight have the same problems. Why did abobe implement a single thread model? Are there any other tricks I can use to ensure my UI is stable.

Performance :: Improve Flex Performance For Invisible Views?

Mar 19, 2012

We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?

Flash :: Silverlight - MVVM - Presentation Model In Flex Vs Presentation Model In Silverlight: Advantages And Disadvantages?

Apr 10, 2011

As it is said here: [URL] "If you do a Google search today for "MVVM and Flex", the first post is by somebody who claims that MVVM is not a good fit for Flex. I couldn't disagree more. Out of the box, the Flex framework makes it much easier to implement a Presentation Model than similar MVVM implementations in Silverlight. That is not to say that there aren't good third-party libraries that make it easier in Silverlight, but without any help, it is easier to do in Flex." So MVVM as LOGICAL CONCEPT can be implemented in both but the way it is implemented in Silverlight requires more Plumbing than Flex.

What prevents Silverlight MVVM to be implemented like Flex ? Doesn't Silverlight have same capability in event system to do the same? If yes why does Silverlight do things more complicated what's the advantages then ? Is it about using Class Interfaces which are more strongly typed? What are the disadvantages also ? For example as for implementing MULTIPLE VIEWS for 1 View-Model does Flex implementation make it also more obvious?

C# :: Async Threaded Tcp Server?

Mar 30, 2010

I want to create a high performance server in C# which could take about ~10k clients. Now i started writing a TcpServer with C# and for each client-connection i open a new thread. I also use one thread to accept the connections. So far so good, works fine.

The server has to deserialize AMF incoming objects do some logic ( like saving the position of a player ) and send some object back ( serializing objects ). I am not worried about the serializing/deserializing part atm.My main concern is that I will have a lot of threads with 10k clients and i've read somewhere that an OS can only hold like a few hunderd threads.

Flex :: Store The Model Of An Application?

Apr 25, 2011

I am working on an StoryBoarding application,it is a slide based application in which the authors can put several components like image , sound , captions etc in each of the slide.A collection of slides will make a storyboard.This application will be deployed on a web server (sharepoint + IIS , and php+apache), and several users can collaborate with each other for authoring or reviewing the storyboard.In my application I also want to support auto save ,which will keep on storing the state of the storyboard.User can also save at any point of time by clicking the save button.I am confused about how to store the state of the storyboard.

1)Presently I am doing this by passing all the storyboard data to a dot net web-service and then that service is storing images,caption etc in their respective tables into a database .2)Another approach possible is to store the model of the application as a serialized object into the db , which will be more convenient since separating the components of the model (like images,captions etc..) will not be required and also restoring the state of the objects in the application will be easy . I have two doubts about using approach 2 :-i) I want the the saved storyboard to load quickly, for which I would like to support the partial so that lighter objects like caption can be loaded quickly but other heavier objects like image,video etc can be loaded on demand. Using approach 2 , do I have to send the whole data in one go or is there way to support partial loading ?

Flex :: Bind XMLListCollection Into Model?

This is a rough example of what I'm trying to do. Adding data to the DataGrid works fine; it just doesn't go into the Model when sending to the HTTPService.

Performance :: Optimization - Improving Performance With Large #'s Of Objects

Jan 11, 2011

I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.

I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.

I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?

Flex :: Cairngorm 3 Presentation Model Initializations?

Jul 13, 2011

I have a TitleWindow that I open up... and I have 6 states defined.I am using the Presentation model pattern for all of my views. When I tell my window to go to XXX state, the controls have to initialize since the states in flex use lazy loading. so... my PM code that says myTextArea.text bombs out and say "cannot access..." so as a work around, I made some creationComplete events on my controls to register the control with the PM. So when the state changes, the textarea finally initializes and on creationComplete calls PM.registerTextArea() which sets a reference to it. then in that function I run my code... myTextArea.text.. etc.

This seems like such a ugly hack that I hate it. Is there any way to wait until the entire state in created then call code on the PM? I have tried enterstate... but this event seems to fire before the state controls are ready.I tried to add a comment, but I guess editing is the only way I can do this...I am doing something slightly off straight PM. Every view has a viewController (as I call them). Its kinda my own hybrid of a delegate / dataprovider. But this is moot. It's the flex component lifecycle when dealing with states that is the pain.if you change state.. there is no event to say "all my components in this state are ready".only event to say "we changed state". so my code that fires on state change is trying to talk to components that aren't ready yet.So from what I see, there seems to be no design pattern or perfect way to ensure that all components are created in a state unless using creationComplete on every component in the state to register it is ready... if you don't, you get a race condition. Regardless of frameworks or design patterns, this seems to be a root issue.

I am trying to attach video to a display once I get to that state. This is done via addchild. regardless of where I do it.. I need to know that the videoDisplay is done loading before I call addchild. I even tried currentStateChange event since docs say that fires last... but alas.. the components in the state are still initializing. So it seems that creationComplete is my only option. Maybe the only sane way to keep to clean code is to create the entire thing(videodisplay and video) using as once the state is entered. I just hoped the flex framework had events to ehlp me here rather than buiilding everything on the fly in as.

Flex :: Update The Model Without Losing Focus In Datagrid?

Jan 25, 2010

In my Flex Project using Cairngorm, I have a model that stores a bindable ArrayCollection displayed by a DataGrid. My problem occurs when the model is updated by the responder (from a Java service, after an "update" event), because the focus located in a cell of the DataGrid is lost (the scroll position il also lost). So, I retrieve the position before the update, with DataGridEvent.ITEM_FOCUS_IN event :

myModel.focusedCell.rowIndex = e.rowIndex;
myModel.focusedCell.columnIndex = e.columnIndex;

But, from where restore these parameters ? How to trigger this update only when the model is updated ?

Actionscript 3 :: Adding Elements In Flex Using Presentation Model

Apr 11, 2011

I'm refactoring some Flex code written by another developer and I'm implementing a PresentationModel approach, as I like to separate out the ActionScript from the MXML. One of the problems I've found is that the original ActionScript code adds/removes elements from the MXML.What happens is the handler function checks the model and if the values are correct will either create or remove a element from the view. What is the best way to get the presentation model to ad elements to the view and still keep this loose coupling that I'm aiming for.I was thinking of using simple events which the presentation model dispatches and a view can list for passing the details of the element to add.

Flex :: Injecting A Specific Model Implementation On The Fly [Robotlegs]?

Jul 25, 2011

Is model injection on the fly possible? In other words,if I ask for a model of the type IPhotoModel, I should get one of its implementations based on the current state of the view. If I am looking at a UserPage,I should get a user-specific implementation of that model.I am looking at a LocationPage,I should get a location-specific implementation.Currently, the only way that I see is introducing a command that specifies the model mapping, with a concrete one based on the current view state ...

injector.mapValue(IPhotoViewModel, injector.getInstance(UserPhotoViewModel)) or
injector.mapValue(IPhotoViewModel, injector.getInstance(LocationPhotoViewModel))

is this the best way possible? I do not really want to introduce much coupling logic outside of the context, but ...
