Я получаю это исключение при попытке использовать вложенные компоненты:

Это мой код для основного компонента:

<base-menu [menu-items-list]="menuList" [menu-layer]="layer"
    (select-menu-item)="selectMenuItem($event)"
    (add-new-item)="addMenuItem($event)"></base-menu>

import {BaseMenuComponent} from '../../../../components/menuComponent/baseMenuComponent/baseMenuComponent';

let applicationPath: string = '/app/pages/adminPage/categoriesPage/requestsPage';

@Component({
    selector: 'companies-Page',
    templateUrl: applicationPath + '/requestsPage.html',
    styleUrls:[ applicationPath + '/requestsPage.css'],
    providers:[RequestTypeService, HTTP_PROVIDERS], 
    directives:[BaseMenuComponent]
})
export class RequestsPage implements OnInit {
    requestTypes:Array<RequestType> = new Array();
    search,Query: string = "";
    menuList = [
        {id:12, layer:0, name:'asd'},
        {id:13, layer:0, name:'asda'},
        {id:14, layer:0, name:'asdd'}];
    layer = 0;
    _requestTypeService:RequestTypeService

    constructor(requestTypeService:RequestTypeService) {
        this._requestTypeService = requestTypeService;
    }

    ngOnInit(){
        //this.getRequestTypesWithFilters();
    }
}

и это дочерний компонент:

import {Component, Input, Output, EventEmitter, OnInit} from 'angular2/core';

@Component({
    selector: 'base-menu',
    //templateUrl: '/app/components/menuComponent/baseMenuComponent/baseMenuComponent.html'
    template:`
    <div class="base-menu-component">
        <ul class="nav nav-pills nav-stacked">
            <li class="form-group row">
                <input class="form-control" [(ngModel)]="newMenuItem"/>
                <button class="btn btn-success" (click)="addMenuItem()">
                    <span class="glyphicon glyphicon-plus"></span>
                </button>
                <button class="btn btn-success" (click)="clearMenuItem()">
                    <span class="glyphicon glyphicon-remove"></span>
                </button>
            </li>
            <li *ngFor="#item of menuItems" [class]="isItemSelected(item) ? 'active':''" (click)="selectItem(item)">
                <a>{{item.name}}</a>
            </li>
        </ul>
    </div>`
})

export class BaseMenuComponent implements OnInit {
    @Input('menu-items-list') menuItemsList:Array<MenuItem>;
    @Input('menu-layer') menuLayer:number;
    @Output('select-menu-item') broadcastMenuItem: EventEmitter<MenuData> = new EventEmitter<MenuData>();
    @Output('add-new-item') broadcastNewItem: EventEmitter<MenuData> = new EventEmitter<MenuData>();

    selectedItem:MenuItem;
    newMenuItem:string;

    constructor() { }

    ngOnInit(){
        this.selectedItem = this.menuItemsList && this.menuItemsList.length > 0 ? this.menuItemsList[0] : null;
        this.newMenuItem = "";
    }

    isItemSelected(menuItem){
        return this.selectedItem == menuItem;
    }

    selectItem(menuItem){
        this.selectedItem = menuItem;
        this.broadcastMenuItem.emit({menuItem:menuItem, menuLayer:this.menuLayer});
    }

    addMenuItem(){
        this.broadcastNewItem.emit({menuItem:this.newMenuItem, menuLayer:this.menuLayer});
        this.clearMenuItem();
    }

    clearMenuItem(){
        this.newMenuItem = "";
    }
}

interface MenuItem{
    id;
    layer;
    parentId;
    name;
}

interface MenuData{
    menuItem;
    menuLayer;
}

Может кто-нибудь объяснить мне, откуда эта ошибка и почему она появляется?
Для меня HTML и оба компонента выглядят очень ясно.
