im having trouble using injector.mapValue , i understand that mapSingleton effectively does the same thing but i need to instantiate the the object since its the return value of another operation.

i am performing this :

`private function LibraryLoaded(hexGfxLib:HexGraphicsLibrary ) : void {



in the execution of one command and then in the execution of the next command i inject :


    public var hexGfxLib : HexGraphicsLibrary;


the two commands are in sequence using the macrobot library for macro commands .

i am recieving the error :

Injector is missing a rule to handle injection into target [object initializeHexGrid]. Target dependency: org.robotlegs.demos.helloflash.model.library.reference::HexGraphicsLibrary

would anyone know the issue ?
( ive tried everything in the common problems section )

    If you remove the injector.injectInto(hexGfxLib); line, the problem is probably gone. You don't need to call this method manually, because the dependencies for your HexGraphicsLibrary class will be automatically injected once an instance of is requested through the getInstance() method of the Injector.

    The documentation for the IInjector interface says about the injectInto() method: "The IInjector should throw an Error if it can't satisfy all dependencies of the injectee." This is exactly what is happening in your example.

    alright found the culprit actually has nothing to do with all of this it was a question of detaining the execution of the command that loads the lib before mapping it.

    Thanks for the help
