Bug(?) in a Multicore version

[sysaux]

Hi all!

I'm new to programming in multicore PureMVC, and i had this run-time error

Code:

Error: multitonKey for this Notifier not yet initialized!

when i wrote in AppStartupCommand

Code:

... AppStartupCommand extends Macrocommand{
override protected function initializeMacroCommand():void{
    addSubCommand(RegisterMediatorCommand);
    sendNotification(ApplicationFacade.STARTED);
    }
}

I get error when I tried to send Notification after executing of some simpleCommands.

Where is a problem?

P.S.:Sorry for my bad English

[puremvc]

In MultiCore you cannot send notifications until after your command (or mediator or proxy) is constructed. The earliest you can call is initializeNotifier, but generally the best practice is to wait until onRegister is called and do any facade manipulation or sending of notifications that need to happen there.

In MultiCore, the INotifiers don't get their reference to ther facade until after they've been constructed. But its best in Standard and MultiCore to defer any notes or facade calls til onRegister. So that the actor doesn't start any 'conversations' it isn't prepared to participate in because it isn't registered yet.

I understood this by experiment))) and now i write my "sendNotofocation..." code on
actor's "onRegister" method.

But anyway - thanks, Cliff! I had some doubt in my solution...
