Help with Flex, Blaze and Cairngorm

[Former Community Member]

I using Blaze, Flex3 and Cairngorm, I have a simple
application at the moment, in which I dispatch a Cairngorm event,
it gets picked up the Command is executed and the Delegate can send
data to the RemoteObject. I can see in the output that Blaze is
doing what it is supposed to do and returning what it is supposed
to return, but the data returned never makes it to the IResponder
result function. What am I doing wrong? Can post code if
needed.

some code and config snippet would be helpful.



btw, how are you monitoring the blazeds output. are you
looking at the blazeds console? try use charles debug proxy to see
the actual network traffic.

BlazeDS Console is where I am seeing the output. I don't see
anywhere to attach code so I will put some here, is there any
particular code you would like to see.

GetUserCommand.as

public class GetUserCommand implements ICommand, IResponder{





public function execute( event : CairngormEvent ): void{

var delegate:GetUserDelegate = new GetUserDelegate(this);

delegate.getUsers();

}



public function result( data : Object ) : void{

Alert.show("We got to a result");

}



GetUserDelegate.as

public class GetUserDelegate{

public function getUsers():void{

var call:AsyncToken;

call = service.getUsers();

Alert.show("Get users was called");

}

Here is the output in the Tomcat console

Found the problem. ... in my Delegate I forgot to
addResponder to the AsyncToken.

Before:

public function getUsers():void{

var call:AsyncToken;

call = service.getUsers();

Alert.show("Get users was called");

}



After:

public function getUsers():void{

var call:AsyncToken;

call = service.getUsers();

call.addResponder(this.responder);

Alert.show("Get users was called");

}
