I am transitioning over to Robotlegs2 and just curious.. (I like RL2 btw.. nice work!)
Do I have to context.detain/release commands that are waiting for an async process?
Do I really have to inject the context for every command?

Thanks!

   Hi Yiotis,

   Your post landed into the spam folder of the forum, for unknown reasons.

   As far as I know only the DirectCommandMapExtension has detain and release.
   [https://github.com/robotlegs/robotlegs-framework/tree/master/src/ro...]

   For the common commands you could create an extension (implementing IExtension) that you install when you create a context. Look at other robotlegs extensions to get an idea about how to create one.
   In this extension you could do something like this:

   public function extend(context:IContext):void
   {
       _context = context;
       _injector = context.injector;
       _eventDispatcher = _injector.getInstance(IEventDispatcher);
   
       _eventDispatcher.addEventListener(PinEvent.DETAIN, detain);
       _eventDispatcher.addEventListener(PinEvent.RELEASE, release);
   }
   private function detain(event:PinEvent):void
   {
       _context.detain(event.instance);
   }
   private function release (event:PinEvent):void
   {
       _context.release (event.instance);
   }
   

   PinEvent is provided by the framework, but you can use your own custom event instead.
   In your command you can dispatch a PinEvent.DETAIN or PinEvent.RELEASE on the shared event dispatcher, or you put this functionality into a base class that the command would extend and you call its methods, which you can name detain and release, if you want to.

   Hope that helps.
