My model does not seem to get injected into my service class, I keep getting a Cannot access a property or method of a null object reference error.

in my context I have the following:

in my service class I Inject the model like so:
[Inject] public var model:MenuModel;

Am i missing something?

    A couple of other "easily to overlook" things to check:

    - Is your Service class mapped (e.g. using injector.mapSingleton()) or
    are you creating an instance yourself?

    - In your Service class, are you accessing "model" in the constructor?
    Injected properties aren't available in the constructor (you can use a
    method marked with [PostConstruct] instead).

    Hi Joe - incase what Paul has said doesn't cover it - we have a section on null injection errors in our 'common problems' document:

    I found the problem, I was creating an instance my self in my command. Thanks.
