@Input and other decorators and inheritance

I don't really understand how object binding works, so if anyone could explain if I can use @Input() inside a base class, or better: decorators and inheritance. For example if each form should receive a customer I have a base class:

export class AbstractCustomerForm{

@Input() customer;
...
}

and then I extend this class in an actual component:

export AwesomeCustomerForm extends AbstractCustomerForm implements OnInit{
    ngOnInit(){

        if(this.customer)
            doSomething();

    }
}

but this won't work, customer will never get set :(

    Inheritance is properly supported since 2.3.0-rc.0

    Decorators are not inherited. They need to be applied to the class used as component directly. Decorators on subclasses are ignored. I have seen it mentioned that @Input() or @Output() are working if only the super class has them and the sub-class has none.
