There's an example on flexdiary.blogspot.com of how to cast a loaded swf to an Interface. You may find that using a Dependency Injection Framework such as Robotlegs simplifies this to the extent you don't need so much documentation. Once you understand how the EventDispatcher backbone (or Event bus, as they like to call it) works, everything's really intuitive.

[flexcoders] Re: Using modules and remote objects
I recently did something like this for Cisco. They needed a way for a sub-Application to invoke a method in another sub-Application, which might not be loaded. The solution was to derive the sub-Applications from a common base class and use the main Application as a broker. The broker listened to function invocation request events. Results of the method calls were made available by a custom event that was dispatched by the called method upon completion. Here is a clue to how to implement this type of mechanism: the SWFLoader that loads a sub-Application has a property called content, which is actually the sub-Application's FlexGlobals.topLevelApplication once the sub-Application loads. Confused? I created a UML sequence diagram, a static object model diagram and a text narrative to document how the mechanism worked. Anyone else attempting something similar is well advised to do the same. Mike
[flexcoders] Re: Using modules and remote objects
I do this all the time. My main application is a shell that loads in the app's layout and loads the menu's based on a users access level. This app then loads whatever module the user is interested in. Each module has all of its functionality encapsulated including its required remoting. This is all using Flex 3.x (Whatever the latest version is) as I don't have time to port it to 4 yet. Can you post some code? Flex as well as server would be good. PHP would be even better. --- In flexcoders@yahoogroups.com, "ZIONIST" wrote: > > Hi guys i have some issues concerning modules and remote objects. i have an > application that is split into modules and in each i use remote objects to > display data from the database. the problem is there is no data being > displayed and when i try to use the same code in a single app without using > modules, the data is displayed. could someone please help me out here. i > really need to use modules because it helps reduce the size of my app. >
Re: [flexcoders] Re: Using modules and remote objects
It depends. Folks who have a large application crunching a single source of data are more likely to put the data classes in the main app and just use the modules to late-load UI and business logic. Folks building portals probably should require 10.1 and use Marshall Plan configurations. It is technically possible to put the data classes in a “never-unload” module and load it into the main-app and load the UI and business logic in a separate module that will unload.

RE: [flexcoders] Re: Using Modules and Remote Objects
Modules and sub-apps have the same rules with respect to RemoteObject. There might be a way to get it to work by having no vestiges of RemoteObject or data classes in the main app and only have them in the child apps, but it is my understanding that there will be issues if some classes are in child apps. You can view the modules presentation on my blog to learn more about applicationDomains so you'll understand the basic principle that limits these kinds of configurations.

[flexcoders] Re: Using Modules and Remote Objects
Thanks, Alex, this is helpful. Does this also hold true if instead of modules, we used applications i.e. a main application from which swf loaders load other sub-applications. In such a scenario, does the RemoteObject and its value objects still have to be in the main application or can they be distributed to sub-applications?

RE: [flexcoders] Re: Using Modules and Remote Objects
Typically, the RemoteObject tags, and all classes being sent and received by RO are in the main app. The Modules only have view classes and no new data classes Alex Harui Flex SDK Developer Adobe Systems Inc.<http://www.adobe.com/> Blog: http://blogs.adobe.com/aharui From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of cortlandian Sent: Sunday, February 22, 2009 4:52 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Using Modules and Remote Objects I have used many other technologies, but am new to flex.

[flexcoders] Re: Using Modules and Remote Objects
I have used many other technologies, but am new to flex. We are porting the front end of a large enterprise application to Flex. Has anyone been using remoteObject with modules, and if so, is there anything different that you had to do in calling your remoteObject usin modules compared to deploying everything in a single application?
