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 ...

I'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.

I have a PresentationModel AS class that holds all the values used in SomeView.mxml. The entire class for the model is bindable, and the model property in the view is also bindable. However, I am unable to inject the model into the view using the PropertyInjector tag:

Since my application is getting bigger, I decided to fragment my project into several modules, but the documentation from Swiz on Modules is very poor [URL]. I tried out the Swiz Examples [URL] but I couldn't inject any data into my module or even catch an event. The module is loaded properly however.
Ideally I will end up having multiple Flex-Projects, each containing one module and each .swf file is deployed into the application deploy folder. However if you aren't familiar with a structure like that, but instead you know how to inject data/event mediating into a module inside the same Flex project.

I'm working on an existing modular project that was built in PureMVC. Instead of converting everything over to RobotLegs, I want to create a new module using RobotLegs and plug it into the pureMVC shell. Currently, when the module loads, I get the following flash error: ReferenceError: Error #1065: Variable IMediatorMap is not defined.
Inititally, I thought it was because my module needed a pureMVC Mediator to call the pureMVC StartupCommand to get things "hooked up" and THEN create the RobotLegs' Context. However, that didn't work and I'm still getting the error.

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?

Okay, I have a swf (2.swf) that current holds text-types for my main.swf (1.swf)
I want to inject a MovieClip symbol from 2.swf into 1.swf's frame(1) without declairing anything about the MovieClip within 1.swf itself... nor do I want to copy the MovieClip across
Is it possible to force the MovieClip from 2.swf into the 1.swf's frame(1)?

I have a Flex frontend connecting via RemoteObject to Zend Framework's Zend Amf. This is my only means to transport data between client layer (Flex) and the application and persistence layers (LAMP with Zend Framework).Some ways I can address security are as follows:
I can address TLS by using mx.messaging.channels.SecureAMFChannel in my services-config.xml file and ensuring Flash player is loaded into a HTTPS wrapper and is in fact using HTTPS since the AMF protocol is layered on top of HTTP RemoteObject has a setCredentials method with which I can pass AMF authentication headers to protect user related data. Assuming TLS was actually secure I can expose methods on the endpoint after authenticating the User.I can protect against cross-site scripting and other FLASH vulnerabilities with a properly set up crossdomain.xml how to I protect my endpoint against another AMF consumer? For instance, if there were another AMF consumer (not Flash so not bound by crossdomain.xml and Flash sandbox security) other than my Flex client that knew my endpoint, what would stop it from using methods that the endpoint exposes?
As far as I know I essentially need a way to authenticate my Flex application against my Zend Amf endpoint. After AMF consumer authentication, I have some of the security mechanisms I mentioned above to protect certain pieces of data (like User authentication). I can not embed some sort of authentication mechanism into my Flex swf because the swf is vulnerable to decompilation (the swf can not be trusted). While sensitive data is protected via User authentication the unprotected data is hardly public but as far as I can tell is totally open for public consumption.

I'm starting a Flex app on a pretty big reporting engine and want to know how best to connect to a Postgres Database. I'd like to create a REST API architecture so I can use the service for more than just the Flex app(mobile possibly).These are my options I've found:
Datatype: either XML, JSON or AMF
Flex Service: HTTPService or WebService
Server(using PHP): ZendAMF, custom json_encode implementation, Zend_Rest_Server
I've got my views all mapped out, and the api functions designed. Basically what I need is advice on which Flex / back-end service combo to provide.

I just upgraded out Flex project to use SDK version 4.5.1.21328 and the Flash Builder to version 4.5
All of the sudden, I'm getting several red tags on the Flash Builder: "could not resolve s:State/fx:Script/whatever to a component implementation"
However, the project builds fine with Maven, and seems to work well too.
Does anyone have any information on how to remove these "problems"?

I'm trying to get my Flash application to connect via socket to my server, so I need to set up a socket policy file server. It seems like there are various roll-your-own implementations floating around out there, but is there any kind of standard or best practice with what to use?
As an aside, it seems strange that Adobe imposes this restriction but doesn't make something readily available to support it.

Within a Chrome extension, how can I inject items into the context menus of 3rd party flash objects?
Is it possible to simply inject items using JavaScript? Is it possible to wrap the players in a container .swf that adds our context menu item along with the items included by the original swf?
Edit: To be clear, what I'd like to do with my extension is add a context menu item to any 3rd party Flash program. So for instance, if a user visits YouTube, I'd like to add my own menu item along with YouTube's custom items.

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 ?

When the XMLListCollection is updated in the DataGrid, I want it to add the XML (bind it) into the Model. How would I do this? Or if not possible, how would I manually add XML into the 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.
