[flexcoders] Re: How to register a dynamicEvent in an Actionscript class

2009-01-13 Thread kylewburke 
I don't know if Cairgorm is anything like PureMVC but if you have a
reference to the UIComponent that you want to dispatch the event, you
would so something like this:

MXML:
MyComponent
mx:Metadata
[Event(name=rowSelected, type=mx.events.DynamicEvent)]
/mx:Metadata
/MyComponent

Then, in AS:
var myComponent:MyComponent;
myComponent.dispatchEvent(rowSelected);

Then again, I could be completely misconstruing what you're trying to
do.  :)

Hmmm, this is the way I have done it - but my event handler is not firing.

I am dispatching my DynamicEvent from a Cairngorm command - in the
execute method I have:

var evt:DynamicEvent = new DynamicEvent(initCompleted);
dispatchEvent(evt);


in my module's creationComplete handler I have this code:

this.addEventListener(initCompleted,initCompletedHandler);



Then in the module's script block I have the event handler

private function initCompletedHandler(event:DynamicEvent):void{
}


This handler never gets hit.

 It's exactly the same as a standard Event.  As you can see in the

 Reference (

 var event:DynamicEvent = new DynamicEvent(credentialsChanged);
   event.name = name;
   event.passsword = password; // misspelling won't be caught!
   dispatchEvent(event);
 
 then..
 
 module.addEventListener(credentialsChanged, myHandler);
 
 The DynamicEvent class works exactly like and Event... it just gives
 you the ability to add properties to it at runtime.  If you're going
 to be using the same event over and over again.  You're better off
 just creating a custom event

(http://livedocs.adobe.com/flex/3/html/help.html?content=createevents_1.html#110674).
 
 If you do not identify an event in the class file with the [Event]
 metadata tag, the MXML compiler generates an error if you try to use
 the event name in MXML. Any component can register an event listener
 for the event in ActionScript by using the addEventListener()method,
 even if you omit the [Event] metadata tag.

Events don't bubble by default.
So if you're depending on the Cairngorm Front Controller to pick them up,
and the object dispatching the event isn't directly below the Application,
you need to enable event bubbling.

new DynamicEvent(myType, true);

Nate

Thanks Nate,

Tried that but it still doesn't work.  I'm basically trying to
dispatch a dynamicEvent from a Cairngorm event and then trying to get
a module to listen for that event.  I don't want this event to be a
CiarngormEvent to be handled by the FrontController and the Command
object.  In other words, I want the module that originally dispatched
the CairngormEvent to handle the DynamicEvent that gets raised by the
CairngormCommand.

I just can't seem to get this to work.
