Reproduce the error

• Place any decorator before the @Component -> KO ❌

@testDecorator
@Component({
  selector: 'app-test1',
  // ...
})
export class Test1Component implements OnInit {
    @Input() text: string = '';
    // ...
}

see in generated documentation.json, Test1Component does not have an inputsClass property.

• Only place other decorator after the @Component -> OK ✔

@Component({
  selector: 'app-test2',
  // ...
})
@testDecorator
export class Test2Component implements OnInit {
    @Input() text: string = '';
    // ...
}

see in generated documentation.json, Test2Component does have a correct inputsClass property.
