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)}"/>

Subject: [flexcoders] Cairngorm2 reusable commands
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
