я есть пользовательский компонент (MyComboBox), внутри которого есть кендо-комбинированный список.

Когда я использую свой основной модуль, компиляция веб-пакета успешно завершается, но Chrome выдает следующую ошибку:

Uncaught Error: Unexpected directive 'MyComboBox' imported by the module 'AppModule'. Please add a @NgModule annotation.

Вот мой AppModule:

app.module.ts

import { MyComboBox } from '@my/core/control/MyComboBox';

@NgModule({
    declarations: [
        AppComponent,
        MyComboBox
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        DragulaModule,
        MyComboBox,
        CoreModule,
        ComboBoxModule
    ],
    entryComponents: [ MyComboBox ],
    // viewProviders: [ DragulaService ],
    providers: [HelperService],
    bootstrap: [AppComponent]
})
