 u can extends the event,add a source attribute to it
 eg:

 public class SourceEvent extends CairngormEvent{

 then inner the viewHelper:

 last,the command is knowed the events.source now!

 Hi all,

 In Cairngorm commands, I always define statically where I want some
 results to be sent (normally a custom function in component that
 extends ViewHelper). This updates my view and works fine. But...

 How can I make that command Class to send some results to whatever
 asked for them (who dispatched the event that threw that command)?

 Eg:

 foobar1.mxml and foobar2.mxml
 ..
 public function setResults(someResults):void {
 //update my controls
 }

 public function getResults():void {
 dispatchEvent(askForResults);
 }
 

 foobar1 and foobar2 dispatch the same event and the command needs to
 know where to send back the results and run setResults on the
 corresponding caller. How can I achieve this?

 Thanks in advance

RE: [flexcoders] Cairngorm2 reusable commands

2006-02-17 Thread João Fernandes

Alberto,

In my opinion commands shouldn't be aware of the views. It's not what cairngorm 
is made for. Dispatch your event and set the result to some variable in your 
ModelLocator. Then if foobar1 and foobar2 need that info, use bindings and bind 
them to that variable ... Do you need to transform that information in a 
different way for each one? Fine, use the Foobar1ViewHelper and 
Foobar2ViewHelper to do it.

Example:

Foobar1.mxml 
mx:Script
![CDATA[   
Import your.model.locator.path.ModelLocator;
[Bindable]
public var model:ModelLocator = 
ModelLocator.getInstance();
]]
/mx:Script
mx:Combobox dataProvider={Foobar1ViewHelper.formatMyModel(model.myVar)}/ 

Foobar2.mxml

mx:Combobox 
dataProvider={Foobar2ViewHelper.formatDifferentlyMyModel(model.myVar)}/

Re: [flexcoders] Cairngorm2 reusable commands

2006-02-17 Thread Alberto Albericio Salvador

Hi Joao,

I dont agree at all hehe For me, it is ok that commands know about views 
(or whatever dispatches the event that started that command)

Imagine this situation:

You have a screen where 2 components ask for the weather on a zip code, 
so I can see weather on 2 locations at the same time. What I say is:

I need both components to dispatch the same event(getWeather) but with 
different parameter (zip code) and get the results back to them using 
the same command. I dont want to use a single application pool to store 
my results.

RE: [flexcoders] Cairngorm2 reusable commands

2006-02-17 Thread Benoit Hediard

I'll second this approach : 
1. use as much as possible the Model Locator and bindings to avoid
commandsviews dependencies,
2. when not sufficient or not elegant, use a viewhelper.

Benoit Hediard (which was using too much viewhelpers at the begining ;) )
