[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 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 event question.
Hi I’m designing my first Cairngorm application and would like to have opinions about events to create. I will definitely have LoginEvent which takes place after user has entered credentials and clicked “Login” button. Should I also create events like LoginSuccessfulEvent, LoginFailedEvent and PasswordExpiredEvent which would happen in result to a server response? I think I should but this being my first project I’m not sure about it and would like to have some feedback from the experts. Thanks Tero No virus found in this incoming message.

RE: [flexcoders] Cairngorm event question.
Not neccesary cause you will handle the response from the server in your result() method. I only create the LoginSuccessEvent to let the main app know, hey all good, show the app now.
