injector.instantiate() and injector.mapSingleton() issue.
injector.mapSingleton(AppModel); var appModel:AppModel =
injector.instantiate(AppModel); appModel =
injector.instantiate(AppModel); appModel =
injector.instantiate(AppModel); appModel =
injector.instantiate(AppModel);
This code create 4 instancies. Is it a normal ? I thought it create only one instance...

Hi Pascal,
The answer to your question is in here:
https://github.com/robotlegs/robotlegs-framework/wiki/Robotlegs-Int...
"instantiate" is used to create an instance of a given class, regardless of whether or not there is a rule for such a class in the container. As such, it must be handed a class, not an interface, and it will always create a new instance. It is used by the CommandMap to create new command instances.
"getInstance", on the other hand, can be handed a class, abstract class, or interface, and it will return an instance based on a previously mapped rule. As such, a rule must exist or an error will be thrown. Also, multiple calls to "getInstance" might return the same instance, whereas "instantiate" will always return a new instance.
