[flexcoders] Cairngorm Event Question
Where can I ask a Cairngorm/Flex Event Question? I posted in the Adobe forum,
but as usual have not received any replies.
The question is how to get something to happen. When the user clicks an item
renderer in one grid I want to populate a second grid with data.
Here are the relevant parts=
UserAA_NmLk_Renderer.mxml:
public static const CLICK:String = 'USER_AA_RETRIEVE_EVENT';
override public function set data(value:Object):void
{
removeAllChildren();
if (value == null ||
value == )
{
return;
}
super.data = value;
var lb2:LinkButton = new LinkButton();
lb2.label = value.individualName +
: + value.rspVer;
lb2.addEventListener(MouseEvent.CLICK, retrieveList);
addChild(lb2);
}
public function retrieveList(event:Event):void
{
dispatchEvent(new Event(UserAA_NmLk_Renderer.CLICK, true, false));
}
Event.as:
public static const USER_AA_RETRIEVE_EVENT:String = UserAARetrieveEvent;
Controller.as:
addCommand( Events.USER_AA_RETRIEVE_EVENT, UserAARetrieveCommand );
When I step through it I get to the dispatch and the proper label appears in
the top grid. But I never get to UserAARetrieveCommand.
I am getting very desperate on this and have been fighting it for days.
Any help including the problem or where to go with the problem will be greatly
appreciated!

[flexcoders] Cairngorm/ Command/ AdvancedDataGrid.expandChildrenOf() ?
Hi, I'm working on a cairngorm flex app and have been told to put all business logic inside the CG Command. At the end of the CG Command, I need to get the ADG to expand it's grouping nodes for a particular node. What is the correct way of solving this problem because from my Command, I can't 'see' the view. Should I update the model from the Command and have a ChangeWatcher on the view to run the AdvancedDataGrid.expandChildrenOf() code? Is there a right and wrong way of solving this? Thanks, Nick

Hey Jake, Cheers for the response... I've gone with a ChangeWatcher approach.

[flexcoders] Cairngorm Problem with Event and ModelLocator
Hi guys,
I'm developing an application with Flex and using Cairngorm framework with the
events, commands, controller, delegates and the services for the remote object,
because my application will connect with a server side.
My component is like that:
mx:VDividedBox xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=initView() width=100%
The initView method will execute a CairngormEvent to access to the database and
get all the users from my system and how many users i have:
[Bindable]
public var model:ModelLocator = ModelLocator.getInstance();
private function initView():void{
//Find all the Users in the database
var findAllUsersEvent:FindAllUsersEvent =
new FindAllUsersEvent();
findAllUsersEvent.dispatch();
var listUsers:ArrayCollection = model.listUsers;
var totalRows:int = model.countUsers;
}
Of course in my ModelLocator i have created the next properties:
public var listUsers:ArrayCollection
public var countUsers:int;
In my command i call the method from the delegate to execute the correct method
of the remote object (it means of my java application running in the server).
In the result method of the command, i assign the value of each properties.
If i debug the application, i get the correct results, but when i check the
value of
var listUsers:ArrayCollection = model.listUsers;
var totalRows:int = model.countUsers;
are not refreshed.
I can imagine my problem is because Flex is asyncronous and when i assign the
values in the initView, maybe the Event is not yet finished.
How can i handle this kind of problem?
I hope all of you have understood me...
Thanks in advance!!
Re: [flexcoders] Cairngorm sub-applications Remoting
Hi, I'm running into this same error with Mate framework, so this is not only Cairngorm-related problem.

Both applications work great on their own. Currently, I'm pointing the source attribute on SWFLoader to the swf location of the sub-application. I'm loading the app into a peer Application Domain (I believe, on the same level as the parent application - both children of the System Domain): _loaderContext.applicationDomain = new ApplicationDomain(); mySubApplication.loaderContext = m_loaderContext; mySubApplication.source = http://xyz:8080/xyz/MySubApp.swf;; I've tried loading the sub-swf into the same App domain, but since they're both Cairngorm apps and use the Cairngorm ServiceLocator singleton, I get the typical singleton error (only one servicelocator can be instantiated). My next option might be to assemble most of the logic in the sub-app into a module. My primary app can load the module and use it's own service framework for remoting (assuming I can get this to work). I can create a separate, light-weight shell container with its own service framework that can also load the same module whenever I want to use the sub-application by itself.

[flexcoders] Cairngorm or Mate?
I've been investigating Cairngorm and Mate to be used in conjunction with BlazeDS. Which is 'better', Cairngorm or Mate? Cairngorm seems a lot heavier, Mate easier to understand and more logical. Also, how many of you are using Blazeds with Cairngorm or Mate with? Is there an evolving standard here? Working examples (I've looked everywhere and many of them or partial or non-functional) of the combinations of these 3 tools? Thanks!
[flexcoders] Cairngorm store example - newbie binding question #2
Thank you Tracy for answering my previous question.
New one:
Why is 'handler' bound to 'confirmOrder' in this snippet?
util:Observe
source={ ShopModelLocator.getInstance().orderConfirmed }
handler={ confirmOrder } /
confirmOrder is a function in the same file.
Is it just a way to set an initial value?
Thanks,

[flexcoders] cairngorm store example - newbie binding question
Greetings Flex pros:
In the modified cairngorm store (if you're familiar), file
ProductsAndCheckoutControlBar.mxml, there's:
mx:Image
source={ getProductThumbnailsButton( model.workflowState ) }
That function (getProductThumbnailsButton) is not marked as 'bindable'
so how does the binding happen?
The var model is the only thing marked as bindable in the file.
This is the function:
public function getProductThumbnailsButton( enforceBining : Number )
: Class
{
var model : ShopModelLocator = ShopModelLocator.getInstance();
var result : Class = model.assets.thumbOff;
if ( model.workflowState ==
ShopModelLocator.VIEWING_PRODUCTS_IN_THUMBNAILS )
{
result = model.assets.thumbOn;
}
return result;
}
RE: [SPAM] [flexcoders] cairngorm store example - newbie binding question
The binding mechanism will cause any function to be called if one of its
arguments is bindable and changes. I don't know the particular app, but I
suspect model.workflowState is bindable.
Bindable really only applies to properties, whether implemented as public
variables or as getter/setters.

Re: [flexcoders] Cairngorm Parallel Commands
I thought the multi-threaded issue was a bit of a red herring too. You should be able to fire two events, one right after the other, without any need to access multi-threading in the Flash Player. I've done this sort of thing plenty of times without issues. From your code is it not obvious what the problem may be. I would suspect the issue is in one of your events / commands, or how they are registered in the FrontController. Getting the code and stepping through it is a good idea. Even w/o the Cairngorm source, you can step over the code you have to make sure that both events are fired.

[flexcoders] cairngorm convention: vo or model?
I have a some doubts about implementing Cairngorm correctly (and I guess MVC in general). I'm trying to decide where to place some of my data storing/transferring classes, and I was wondering if anyone has any rules of thumb for this kind of thing. These are the guidelines that I have been following until now: 1) the class only transfers data to/from a server: postfix VO and put it in the vo folder 2) the class only stores data for the local application: put it in the model folder 3) the class does both of the above: put it in the model folder (don't postfix VO) I'm working with someone who does (1) even when the class is never sent across the wire. What's the right way to do this? And also: I've read somewhere that VO's should not contain any logic, and that you should be able to initialise all of its properties via the constructor. What do you think? TIA! -Jorge
Re: [flexcoders] cairngorm convention: vo or model?
Ultimately the data should be in the model, and the view binds to the model. However depending on your needs you could notify the view from the command using responders.

RE: [flexcoders] cairngorm convention: vo or model?
What about transient data? I was always under the impression that VO’s (or DTO’s or whatever they’re called) were more like throw-away objects: you use them to transfer data to/from a server, but that’s it. So if I label something as being a VO (e.g. ConversationVO), then I don’t expect to find that class in the “model” classpath because I am not storing data in it.

Re: [flexcoders] cairngorm convention: vo or model?
You are right, If your data is only transport stuff and then get rid of it it does not justify to put it in the model. If you need your data displayed in the view then your data will probably be in the model. It depends on your business case. The VO is just a name in the end... you can label a class with VO or not it is how you use it what matters. You can transport data with VO objects (classes with no methods) and put it inside other model classes (put a clone method inside that class to move data from VO). But in many cases this is not justified. For example you want to login, you get the username and pass form the textfield inside a VO. Attach that VO as a payload to the cairngorm event and send it to the server via command/delegate etc ... That is a case where you just transport data ... no need ot store it in the model ... If you get data from the server like some products and want to display them in the view, you can pu them in the model and use the model as a dataprovider for a list or whatever ...

RE: [flexcoders] cairngorm convention: vo or model?
Ok, so if I’m understanding you correctly, you don’t have a problem storing a VO in some part of the model (assuming that the VO is used for both transport and storage)? In my Cairngorm project, the directory structure looks like this: business control commands events model view vo So if I do what you suggest, and allow for a VO to reside in the model, then the model will contain stuff that does not reside in the model directory, which feels kinda weird to me.

Re: [flexcoders] cairngorm convention: vo or model?
1) the class only transfers data to/from a server: postfix VO and put it in the vo folder I'm working with someone who does (1) even when the class is never sent across the wire. That's what I do as well. Doesn't matter if it's meant for transfering data to/from server or not. They certainly don't belong in the model package though, that's where the model belongs, not data classes. If you prefer having a distinction between objects that will be sent to server and those that won't, maybe use a data and a vo package.

Re: [flexcoders] cairngorm convention: vo or model?
What if you have a class that is both a vo and a part of the model (the situation I mentioned in my original post)? Should you clone the vo and put it in the model, as Claudiu mentioned? What do you mean by part of the model; it is used by the model? If so, why does that matter? VO's should be in the vo package, nowhere else. I followed the structure used by David Tucker Well, Cairngorm has a few things backwards (IMO), like CairngormEvent and CairngormEventDispatcher both being in the control package.

RE: [flexcoders] cairngorm convention: vo or model?
What do you mean by part of the model I just sent a post where I (hopefully) explained what I mean by part of the model. If so, why does that matter? This goes back to my definition of VO: objects that are sent across the wire. So my reasoning was that if you send something across the wire and it's not part of the model, then it should be in the vo package. Additionally, I reasoned (perhaps incorrectly) that anything that is not sent down the wire should not get the name VO and should reside in the model package, not the vo package. For me, the vo package is only for stuff that gets sent down the wire. Cairngorm has a few things backwards Tell me about it..

[flexcoders] Cairngorm sub-applications Remoting
Has anyone written two distinct Cairngorm-based applications, each capable of dispatching service calls (via RemoteObject) and tried loading one inside of the other? Essentially I have a parent application that uses SWFLoader to load a sub-application (in a peer Application Domain). The sub-application loads visually within the parent application but service calls from the sub-application result in a runtime error: TypeError: Error #1034: Type Coercion failed: cannot convert obj...@x to mx.messaging.messages.ErrorMessage. JBOSS logs show this: No destination with id 'null' is registered with any service. The first error appears to be a class-aliasing problem, but both of these apps are Cairngorm-based Flex applications...the registerClassAlias method shouldn't be required (besides, I tried that tactic already to no avail). This is the only Flex-equivalent of a bat-signal I can think of ;) Erich
Re: [flexcoders] Cairngorm sub-applications Remoting
The 'destination null' seems to imply that your Flex-side remoting metadata is fubared. It's trying to contact a destination that was not configured--or somehow got unconfigured through the peer-appdomain swf loading. I've asked about doing something similar with Modules, and was told by Adobe folks on the list that this would be a Bad Idea. However, I believe they suggested separate apps--just as you are doing.

[flexcoders] Cairngorm Question
Hello Group, This is my first question on this group and I have been referring to this group for all my technical challenges with Flex (started using 1 month back). Thanks for such a nice group and support. I have a complex screen where I have 2 Combo boxes and by default Combo-2 is disabled and will be enabled only when user selects Combo-1 and Server returns any Objects for Combo-2 otherwise it will be still disabled. I have defined an Event `LoadCombo2Event' which is dispatched when user selects an entry from Combo-1 and the results will be handled in `LoadComb2Command'. I do not have access to Combo2 in this command to Enable or Disable? How do we handle this case using Cairngorm? Thanks, Sre

[flexcoders] Cairngorm v/s others
I've been using Cairngorm for a while now and I've gotten pretty used to it. I want to try out the other Flex frameworks too but will I need them if I can get most of my work done using Cairngorm.

RE: [flexcoders] Cairngorm v/s others
I really don't know much about the others like Mate and PureMVC so I will only look into them if they've got sufficient advantages of Cairngorm. Any inputs? We are using Cairngorm but have implemented an alternative notification mechanism similar to what is included in PureMVC. The problem we wanted to address was being able to notify a number of different parts of the program that a service call was complete. This didn't fit well with the event/command relationship within Cairngorm. Previously in this forum, we discussed test-driven development and the issues that this raised. Test-driven development is really about design and not validation. In order to allow my tests to drive the design, what might be considered a view is split into two components. An mxml view that relies primarily on data binding and a supervising controller (Fowler 2006). The supervising controller is written in ActionScript and inherits the base component for the view. It then forms the base component for the mxml view. This makes the supervising controller and the mxml view appear to be closely bound. The supervising controller knows nothing of the mxml view. The mxml view calls functions in the supervising controller to get anything done and passes as parameters in those functions any data that the supervising controller may need. Basically, I wouldn't use Cairngorm in the future nor PureMVC nor any other framework. Most contain a very limited amount of code. The most useful part being something that allows notifications or the queuing of events. Cairngorm provides the services locator but that needs to be mocked out if you want to run tests that don't land up calling the remote server. I have achieved this but it suggests to me that there are more flexible solutions. I see Cairngorm and PureMVC as primarily providing conventions to follow to implement solutions. The problem is that it is unclear what problems those conventions address and the nature of the consequences of applying these conventions. I have blogged on this at http://kiwi-et.blogspot.com/2008/12/flex-mvc-frameworks.html.

[flexcoders] Cairngorm for AS3 projects?
Is there any reason not to use cairngorm for AS3 projects. I know cairngorm uses classes in the mx.* range so its using some flex framework code (and I assume that means adding the 126kb framework code at least..) is there a framework AS3 projects use instead? thanks

Re: [flexcoders] Cairngorm for AS3 projects?
Hi Rick, In the past we developed several AS2 Flash (not Flex) applications in Cairngorm. In the current version of of Cairngorm almost all of the dependencies on mx packages are in the ServiceLocator, which used not to be the case with earlier Cairngorm versions. You can roll your own old style ServiceLocator using the singleton code from the comments in IModelLocator (maybe also make the class dynamic). The only other thing you'll miss is bindings, which are God's gift to MVC developers although somehow they seem to be something the other Flex frameworks try to avoid using for some reason I fail to fathom... oops I'm ranting. Anyway without binding the ViewHelper pattern can help - this also used to be part of Cairngorm, although now deprecated. Here's an old blog post of ours with an example of Cairngorm (I think 0.99) in a Flash project: http://www.rocketboots.com/blog/index.cfm?mode=entryentry=83219052-E081-51EF-A73B5F4EF642C3F5 Cheers, Robin ROBIN HILLIARD Chief Executive Officer [EMAIL PROTECTED] RocketBoots Pty Ltd Level 11 189 Kent Street Sydney NSW 2001 Australia Phone +61 2 9323 2507 Facsimile +61 2 9323 2501 Mobile +61 418 414 341 www.rocketboots.com.au On 14/11/2008, at 12:03 AM, Rick Schmitty wrote: Is there any reason not to use cairngorm for AS3 projects.

Re: [flexcoders] Cairngorm: should pure view state changes go through the ModelLocator?
Le 24 oct. 08 à 03:48, Dimitrios Gianninas a écrit : #2 because your app is simple..#1 if you want to be a purist. start simply and add complexity as you go along, thats my rule. That's a good rule ! If your 2 components in your view are in the same component, let's say whatever Panel or Canvas you can think of , I don't see why you should go all the MVC way. Farid
Re: [flexcoders] Cairngorm: should pure view state changes go through the ModelLocator?
I also vote for #2. Seems strange for me to have a boolean in the ModelLocator that is specific to this UI context. I always thought the ModelLocator should only have data that is potentially global to the app (like your list of users), and find it strange that many online Cairngorm examples put something like the working item of an edit form (e.g., you have a form that edits the properties of a specific user, and a variable for that user is added to the ModelLocator). So I wouldn't consider your boolean flags to be part of your app's model.

Hi everyone, Here's a design question for you Cairngorm experts. In my application's view, I have two main subcomponents: a control bar sort of custom component that I wrote that we'll call the FrabjousControlBar, and a DataGrid, which lists all the users in my application. These users are either Administrators or Members. The FrabjousControlBar contains two checkboxes: a checkbox labeled Show Administrators and a checkbox labeled Show Members. Both are checked by default, but when Show Administrators is unchecked, the DataGrid removes all of the Administrators. Something similar happens for Show Members. I'm having trouble choosing the correct implementation for this. There are two ways I can see to do this: 1) When a user unchecks Show Administrators, the control kicks off a Cairngorm Event, the controller executes a Command that changes a boolean flag in the ModelLocator, and the DataGrid responds to the change on that flag. 2) Since the user interaction affects the view only, no MVC round trip occurs. My view knows when the box is unchecked and updates the DataGrid accordingly. Which is better? 1) is more pleasingly MVC, but comes with a lot of overhead and additional effort.

[flexcoders] Cairngorm AMFPHP Problem
Hello,
I am trying to convert an existing Flex/AMFPHP app to Cairngorm but am
having trouble returning value objects from PHP.
public function login($userVO)
{
$user = new UserVO();
// yada yada yada, user authenticated, logged and full details
received
$user-id = pg_fetch_result($result, 0, id);
$user-email = pg_fetch_result($result, 0, email);
$user-username = pg_fetch_result($result, 0, name);
$user-lastIP = pg_fetch_result($result, 0, last_ip);
$user-password = pg_fetch_result($result, 0, passhash);
$user-level = pg_fetch_result($result, 0, level);
return $user;
}
Here is the error I get from Flash Player:
ArgumentError: Error #1063: Argument count mismatch on ...
vo::UserVO(). Expected 2, got 0.
Here is what I get from the fault handler:
Didn't receive an acknowledged message.
Was expecting mx.messaging.messages.AcknowledgeMessage, but
received null.
Hopefully, what I am doing will be painfully obvious to someone.
Thank you in advance for any help,
Orville

[flexcoders] Cairngorm Update Problem
I am working on a Cairngorm project. I am using a ViewStack component to flip the user interface between a graph component and a filter data component both in the view layer. The basic concept of the application is to have a line graph and allow the users to filter the data using an input screen. All of this works the first time the user enters the application and uses the filter option. The problem I am having is the second or third time the user enters the filter screen. I cannot find a way to tell the graph component to reset itself after the event is dispatch and the controller takes over and new data needs to be displayed in the graph. (IE remove any annotationElements that were on the old graph) Is there a way to notify the component in the view layer of a Cairngorm project from the command layer when the results are return from the delegate? Thanks, ~Chris
RE: [flexcoders] Cairngorm Update Problem
You could put a property on the model that the component can bind to, that way the command could just update the model after the delegate returns and databinding will take care of the rest for you. I personally don't like keeping state properties like that in my model, so I usually use Cairngorm Extensions. You should check out their Callbacks model -- it solves your exact problem and is the functionality that turned me on to it. If you are already too far along in your project to switch to extensions, I'd go with the first option for the quick fix. http://umcairngorm.riaforge.org/ http://code.google.com/p/flexcairngorm/ HTH, Ryan From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of c_higgon Sent: Wednesday, September 24, 2008 3:45 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Cairngorm Update Problem I am working on a Cairngorm project.

RE: [flexcoders] Cairngorm - BlazeDS Example
If you have BlazeDS and looked at the examples, then you know how to connect to
the backend.
To do in Caingorm, just read the docs: http://www.cairngormdocs.org/
http://www.cairngormdocs.org/
Basically your command class will use a delegate class to call the server. The
delegate class will use the ServiceLocator to get a reference to the
appropriate service defined in the Services.mxml file.

[flexcoders] cairngorm/remoteObject/VO - my first crack
Good day listers.
I got this crazy idea I should have a crack at learning cairngorm/
remoteObject (amfphp) /VO all at once
I had previously been using netconnections for my amfphp stuff.
At any rate, I was wondering if someone could look over my code to see
any blaring no no's in it.
The app really does nothing, and is just a test to learn it all.
I have a few small issues in my LoadVoDataCommand file.
I have comments in there stating what the issues are (even though
there are no compile errors).
The link is:
http://apps.bajamining.com/flexcoders
For some reason in the source view, the PHP files come up as blank.
However they are in the zip file download (I checked).
But they are also so short, I will just add them into here for those
who do not want to download the zip to just look at 2 php files.

[flexcoders] Cairngorm concepts
I have the past few days reading about Cairngorm and, at all, i don't understand the concept behind de events and commands. The people says that a event-command pair corresponds to a user gesture or system event: clicks, app init, etc. But when i browse the Cairngorm store app i found things like these: - Command modifies the model and the model notifies the view throw bindings: this seems logic to me. - Selecting a product in the view directly changes the model.selectedItem: where is the command?. What we have here is a user gesture and a model update without Cairngorm event or command. - Retrieving the products with a GetProductsCommand: what kind of event+command is this?. The system event shold be appInit or the like, and then usually you need to retrieve many things, not only products. Why server request = command? - Finally, the checkout process is divided in a sequence of commands. The user gesture is checkout, but the app uses serveral commands. This has no sense for me. I think the theory was right, but when applied is twisted to match the framework limitations. This is suposed to be the mother of the samples (an the only one, i think). Could any one clarify me when to use a command an how to explain the concept to other people? Thanks - Oscar

RE: [flexcoders] Cairngorm Result and Fault Handlers not called
Which version of Cairngorm are you using? seems like an old one. At quick
glance your code seems fine.
Not really sure what to recommend except maybe upgrade to version 2.2.1? You
dont have to do that call to loadWSDL(), it is taken of for you.
Here is that the delegate should look like:
public class AgentDelegate {
private var service:Object;
private var responder:IResponder;
public function AgentDelegate( responder:IResponder ) {
service = ServiceLocator.getInstance().getWebService( agentServices );
this.responder = responder;
}
public function search( criteria:String ):void {
var call:AsyncToken = service.search( criteria );
call.addResponder( responder );
}
}
And here is the Command class:
public class SearchAgentCmd implements ICommand, IResponder {
public function SearchAgentCmd() {
}
public function execute( event:CairngormEvent ):void {
var evt:SearchAgentEvent = event as SearchAgentEvent;
var delegate:AgentDelegate = new AgentDelegate( this );
delegate.search( evt.name );
}
public function result( event:Object ):void {
var evt:ResultEvent = event as ResultEvent;
UserModel.getInstance().agentSearchResults = evt.result as ArrayCollection;
}
public function fault( event:Object ):void {
var evt:FaultEvent = event as FaultEvent;
//show error message somehow
}
}

[flexcoders] Cairngorm Event Question
I have been building on my cairngorm experience and have come up to a snag. I understand the whole idea about using the controller to trap and respond to events, however, how do I deal with custom view components that need to respond to an event. For example, I have a custom component that contains an advanced data grid. I am filling the modelLocator with data from the server and using this as the data provider for the advanced data grid. The problem I have is when the user selects a different date, I generate a cairngorm event to load new data from the server. This information is dealt with in the controller, however, I am not able to send the event to the custom component to refresh the advance data grid and display the data. Would someone help me to understand how I can use the events, or generate a new custom event to trigger some activity within a custom view component Thanks for the help Don
Re: [flexcoders] Cairngorm Event Question
You can try Universal Mind Cairngorm Extensions: http://code.google.com/p/flexcairngorm/ Among others it has these Event features: - Built-in support to transport responders for direct view or business logic callbacks. - Implementation of AnnounceFaultEvent to allow business logic to centralize error reporting and logging. - Implementation of EventGenerator to allow developers to automate dispatching of sequences of events. - Events now should self-dispatch... for direct deliver to the business/controller layer.

[flexcoders] cairngorm and webservice demo?

[flexcoders] Cairngorm: bundling functions to complete a task?
Example: read a local shared object when user logs on, and send value
from local shared object to back-end. The only example I have found of
Cairngorm executing a use case of more than one function is a
Cairnstore version where ValidateCreditCardCommand needs to continue
with CompletePurchaseCommand. It does this by creating the next
event i.e. when the Validate command has done its thing, it calls its
executeNextCommand()
method which
public override function executeNextCommand() : void
{
// Create the next event.
var purchaseEvent : PurchaseCompleteEvent = new
PurchaseCompleteEvent();
// Dispatch the event.
nextEvent = purchaseEvent;
super.executeNextCommand();
// Clear the event.
nextEvent = null;
}
Is this how one approaches more complex tasks in Cairngorm?
So I would encapsulate the SO read in a event/command/delegate trio,
and then call a value to backend trio by generating its event from the
SO command. If this is the Cairngorm way, would I try to pass the read
in SO value with the command generated event, or should I write the
value to the ModelLocator, and then read it back from the ModelLocator
with the command of the second event? TIA,
Mic
[flexcoders] Cairngorm - always event, always command?
pseudocode:
creationComplete
var ipAddress:String
ipAddress = getUserIP()
function getuserIP():String{
// use Services to go out to ColdFusion which can tell me user IP
return IP
}
But Cairngorm encapsulates actions into commands which are driven by
an event and a delegate. So how does it handle examples like the one
above? Should I create a getIP event, which is dispatched from
creationComplete, and use the standard command/delegate path. If the
event is not necessary, and it still makes sense to put the action
in a command, how would that command get activated without the
Cairngorm event process? I know what I mean grin. TIA,
Mic.
RE: [flexcoders] Cairngorm - always event, always command?
I can't see how you'd benefit from sidestepping the cairngorm event - command
way of working in this case.
If you use a service to get the IP address then it's asynchronous, and has a
few possible outcomes.
I can't see why you wouldn't want to wait for it's got one of those results or
an error event and then deal with the outcome.
Which is where the cairngorm way of doing things is really helpful.
If it's synchronous (like opening a database or prefs file in AIR, say), then
you could maybe skip cairngorm (I do, and get away with it, mostly).
In which case I can't see the benefit of thinking of (or packaging ) it as a
cairngorm command. I'd rather put it somewhere else and know it was a different
thing.
But what I've found most of the time is that if you're going to do a cairngorm
app then it's really worth going with the flow and doing pretty well everything
that way,
even if it does mean writing 3 classes when you could get away with a local
method.
Generally, when I've made short cuts like that it's come back and bitten me on
the arse.
I do still do it when I'm in experimental/creative or lazy mode, but now I'll
try to refactor it into the cairngorm way sooner rather than later.
Which is sometimes a bit boring, but there you go.
Hope that makes (at least some) sense!

[flexcoders] Cairngorm Model Locator
Hello! I'm currently creating the software design for a large application which we are going to build using Flex 3, Cairngorm 2.2.1 and SabreAMF (PHP). I have already created my first prove of concept, however, I have a few issues with Cairngorm's Model Locator. 1) How can I make sure that unused data gets removed from the Model Locator? The simple solution would be to destroy the data that a view loaded when the view gets closed. However, we are going to use flexmdi and it's quite possible that one or more MDI windows are using the same data. The only solution I've come up so far is to make the Model Locator aware of which window uses which data. Therefore it could free the unused data when no view uses it anymore. Yet, this could be a very error-prone solution. Moreover, I would loose the last bit of loose coupling. So, I'm not sure if that's a good way to handle this. Well, the Model Locator itself is often seen as an anti-pattern as well ... 2) Should I really put everything into _one_ Model Locator? I guess there could be quite a large number of public variables. Our application will have up to 50 different views and about twice as many VO ... I'd be really grateful if somebody could enlighten my ;-) or if you could give me some tips on how to solve those two problems. Thanks in advance for your help. Best regards, Gerhard
RE: [flexcoders] Cairngorm Model Locator
Gerhard, One approach I took is to have localized models that apply to specific modules in the application, as opposed to having a proliferation of variables that apply across multiple aspects of the application, which could get ugly. They still could live in the singleton Model Locator, but could be condition 're-set' when no longer used or needed to be refreshed. Like ModelLocator.getInstance().mylocalModel = new MyLocalModel(). I'd think there'll be a lot of oppinions about how to approach this.

Re: [flexcoders] Cairngorm Model Locator
You definitely don't want your model keeping track of views using its data. My 30 second recommendation would be to look into the UM Cairngorm extensions as they can help you reduce the amount of clutter that needs to be stored on the/a model. Specifically view callbacks is the feature that helps enable that. Search flexcoders for additional discussion of UM Cairngorm.

Yet, this could be a very error-prone solution. Moreover, I would loose the last bit of loose coupling. So, I'm not sure if that's a good way to handle this. Well, the Model Locator itself is often seen as an anti-pattern as well ... 2) Should I really put everything into _one_ Model Locator? I guess there could be quite a large number of public variables. Our application will have up to 50 different views and about twice as many VO ... I'd be really grateful if somebody could enlighten my ;-) or if you could give me some tips on how to solve those two problems. Thanks in advance for your help. Best regards, Gerhard
[flexcoders] Cairngorm - reload wsdl file
Hi all, I'm creating an app using Cairngorm and Swf Studio. (The app runs form CD) While the application initializes i need to talk to a webservice. The problem is that the service locator class loads the wsdl file automatically. If the user is not online the wsdl can obviously not be loaded. In this case I want to display an error message (e.g. please check your connection...) If the user presses ok I want to reload the wsdl before I attempt to make another service call. Is there any way I can reload the wsdl file or re-initialize the service locator? Thanks Robin
