Title: Why null ?
Post by: davidTikva on January 09, 2011, 11:01:52
I moved from standard to multiCore, and of course, it's pretty much the same
and as for my problem, I don't think it's matter:

I'm creating a facade in this way:

public function MyFacade(key:String)

this is the getInstance function:
public static function getInstance(key:String) : MyFacade
      if(instanceMap[key] == null) instanceMap[key] = new MyFacade(key);
   return MyFacade(instanceMap[key]);

this is the initializeController function:
override protected function initializeController():void
         registerCommand( ShellConsts.STARTUP, StartupCommand );

I get on this function this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
   at org.puremvc.as3.multicore.patterns.facade::Facade/registerCommand()

why is that?  :o

thanks in advanced

You need to call super.initializeController() first. Here's what's not happening when you fail to do that in MultiCore:

       protected function initializeController( ):void {
            if ( controller != null ) return;
            controller = Controller.getInstance( multitonKey );
