[flexcoders] Re: Transferring Data through Cairngorm methodology
Sorry for the late reply.
Ben you and Paul are correct your fixes work fine for me thanks.
I also checked out that login example, but my problem with the login
example, is that instead of passing data into the backend service,
which is what my java beans are set to accept, they want to pass a
fully constructed AS object.
Now I understand both could work, but I wanted to know specifically
how to do it passing data. The reason is, that in the instance I am
consulted to rewrite an existing java app, I want to be able to pass
exaclty what is there already so as little backend pieces need to be
re-written as possible.
Thanks all for your help.

Heres the deal.
Basically I have a button which calls a doLogin() function.
private function doLogin():void

var event : AuthenticateEvent = new
AuthenticateEvent(AuthenticateEvent.EVENT_LOGIN);
event.loginName = loginName.text;
event.password = password.text;
CairngormEventDispatcher.getInstance().dispatchEvent( event );
}
this is called from my mxml display page. loginName and password are
text fields on my screen.
The controller is loaded from the main.mxml file, and is already
instantiated, but here is the add command reference for this login
function.
public function initialiseCommands() : void
{
addCommand( AuthenticateEvent.EVENT_LOGIN, LoginCommand );
}
From there the loginCommand.as is called and runs its execute method:
public function execute (event : CairngormEvent):void
{
if( !CruiseModelLocator.getInstance().authenticated )
{
var delegate : LoginDelegate = new LoginDelegate( this );
delegate.doLogin(event.data.loginName, event.data.password);
}
else
{
Alert.show( Logged In already! );
return;
}
}
The delegate is below:
public function LoginDelegate( responder : Responder )
{
this.service = ServiceLocator.getInstance().getService(
UserManager );
this.responder = responder;
}
public function doLogin(loginName:String, password:String) : void
{
var call : Object = service.login(loginName,password);
call.resultHandler = responder.onResult;
call.faultHandler = responder.onFault;
}
I must be doing something wrong here. But basically I am getting lost
trying to pass the values of those two text boxes, and getting them
all the way through this methodology to the remote object service i am
going to call. It looks for two parameters, loginName and password,
and in this test case loginName actually equals the string loginName
thats the value.
I have traced the debugger and even gone through the cairngorm ASDoc
stuff, and cannot figure out what I am doing wrong. It mentions the
data attribute, and when I pass into the execute function on the
command, event.data or event.data.loginName I dont get a compile time
error. However nothing is being passed to the service.
When I look at the debugger trace I see that event does have a
event.data attribute, but its undefined, and also that event has a
event.loginName, and a event.password. Note this is correct, its not
event.data.loginName, but rather event.loginName, and the value is
there from those text boxes.
So it is there, but it dont work. If I pass into the command,
event.loginName I get a compile time error. However it shows in the
debugger as being there. I dont get it.
I am a newbie to OOP and flex and java, so this could be a really
stupid question. Any help would be greatly appreciated.

O and one other thing, when I created the authenticate event class, I
created two params
public var loginName : String;
public var password : String;
I dont know if thats important or not.

RE: [flexcoders] Re: Transferring Data through Cairngorm methodology
I think you will need to perform a cast to access the properties of your
AuthenticateEvent instance (this is why you got a compiler error). The
cast is achieved as follows:
var authenticateEvent : AuthenticateEvent = AuthenticateEvent( event );
So your command's execute function will look like this:
public function execute (event : CairngormEvent):void
{
if( !CruiseModelLocator.getInstance().authenticated )
{
var delegate : LoginDelegate = new LoginDelegate( this );
// Do a cast
var authenticateEvent : AuthenticateEvent = AuthenticateEvent( event
);
// Now extract your login details
var loginName = authenticateEvent.loginName;
var password = authenticateEvent.password;
// Pass details to your delegate
delegate.doLogin(loginName, password);
}
else
{
Alert.show( Logged In already! );
return;
}
}
I hope this solves your problem, but feel free to post again if you are
unfamiliar with casting and need more explanation.
Paul
