I'm using MATE on an Adobe Flex project for MVC. On one of our pages, we have a dialog window that is presented to the user that displays them information that comes from RPC. The pages where this dialog pops up is unrelated to the data being displayed so this is a separate model. How do I create a MATE mapping file that will create the dialog window, make it visible to the user, and then inject in data from a model?
View 1 RepliesIs there any kind of a standard for the location (padding) and size of the usual "ok" and "cancel" buttons on a Flex pop-up dialog box? In another stackoverflow question it was suggested that the approach be host operating system dependent (e.g. Windows vs Mac vs Linux).

View 1 RepliesI am developing a a game in Flash using the PureMVC framework. From time to time I need to show dialog pop-up window to get a user response back (e.g. "Cancel", "OK" and other kinds of asynchronous user feedback) while "locking" the background for interactivity.
I need some management for my pop-ups: all pop-up notifications should be stacked up, so that if two (or more) pop-up messages are initiated at the same time I show them one by one.
What's the best practice here? Should I employ a proxy to manage my pop-ups (sounds unreasonable). How do I get feedback back from my dialog? using notifications?

View 1 RepliesI am trying to get the Privacy Settings Tab to show in our flash/flex4 video chat application we are building.I have 2 systems with latest Flash installed (currently 11.1.102.62). However, the player always shows this (privacy popup question) instead of this (privacy settings tab) when loading the app.The reason i want the settings tab to show is because i need the end user to easily check the "remember" box. I have tried to call Security.showSettings(SecurityPanel.PRIVACY); before as well as after the getCamera/getMicrophone calls but all that happens is we get 2 popups instead of 1.and still no "remember" option.Actually it doesnt show the privacy tab at all!Searched tons of forums but have come up empty.I have also searched the adobe docs but all I find is a paragraph stating"if your computer or device doesn't support audio or video recording using Flash Player, you don't need to allow or deny access, and this panel doesn't appear".Which is hardly true since one of the systems we are testing with is a new Macbook Air running latest OSX.Does anyone have any insight into why this might be happening and how to display the "Privacy Settings" and not the "Privacy pop-up question"?
View 1 RepliesIf you create a popup via:[code]It will create a popup and bring it on top of any other visual piece. I have one problem though. This 'popup' needs to stay up even when the user interacts with the background.I would use modal, but I need the ability to interact with the back. Any way to tell the popup manager not to remove the popup when the user clicks off of it?
View 1 RepliesAs 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?
I need to close the popup(adobe flex), non modal window if I click on the parent page of the popup. I have to do the out of focus check and then do some validation before close the popup. So what I was thinking that is there any inbuilt focus check event or do we need to create custom event for that?
View 1 RepliesI have a web application which contains a data grid. Double clicking on any row of that grid will open a popup (lets call it popup1).

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 ?
In Flex world, is DTO / VO same as Presentation Model?

View 1 RepliesOver 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.
i have a question about Zend Framework and mainly the model part. I know there is no abstract model class and understand why. I red a lot of blog posts about it, but couldn't find any example that would clearly explain it to me. I'm building a very basic application. Lets imagine we have just three tables.company(ID, name, street, streetNo, Town), meta(ID, name, description), company2meta(ID, companyID, metaID, value, note). All types of realtionship are there (1n n1, nm). The a need also services (amf) with Value Objects. So, here is what I think:

I have designed "the core" of the application i am working on ( it communication with the server, data processing, etc. ), and now i am a bit stuck on the User Interface, because i wish it to be specific, and probably different on the different platforms it goin to run on ( PC, tablet, gsm ).
My question basically is How to separate the "core" of the application, which must remain the same for all of the platforms, from the UI's which shall be very different applications ?
In Cairngorm (Flex Framework), there is Model Locator Pattern, which is similar to Global variables, is it a right pattern, Adobe is saying for flex its best pattern

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.

View 1 RepliesIn an AIR application I have the following code:
theDialog = PopUpManager.createPopUp( this, TheDialogClass, true ) as TheDialogClass;
theDialog.addEventListener(FlexEvent.CREATION_COMPLETE, cpuIntensiveCalc);
At the end of cpuIntensiveCalc the dialog is removed. The dialog informs the user that "something is going on, please stand by."
The problem is that cpuIntensiveCalc starts before the dialog draws. So the user experience is that the application freezes for 10 seconds with no indicator, then the modal dialog flashes quickly (less than a second) on screen.
The Adobe docs say this about creation_complete
Dispatched when the component has finished its construction, property processing, measuring, layout, and drawing.
So this feels like the correct event. In the name of completeness, I also tried
theDialog = PopUpManager.createPopUp( this, TheDialogClass, true ) as TheDialogClass;
cpuIntensiveCalc();
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 ?
I have data model (dataProvider as ArrayCollection) i want to display in few views , each view should show filtered data. As you probably know, filterFunction is property of ArrayCollection,so I can't use this solution (unless creating new instance of ArrayCollection for each view on top original and impementing filterFunction).
View 2 RepliesI have a DAE model that is parsed into several parts. I am able to deal with them separately, such as changing their material or colour but I am having problems adding click or hover listeners over the children. For example, lets say I have a model of a kitty where each facial feature is a child. I want to be able to hover or click the features and have a window pop up explaining the feature.

View 1 RepliesI'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.
View 2 RepliesIs 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 ...
