NG2-Bootstrap タイプアヘッドを実装しようとしていますが、成功しません。
これは私のコードです:
import {Component} from "angular2/core";
import {CORE_DIRECTIVES, FORM_DIRECTIVES} from 'angular2/common';
import {TYPEAHEAD_DIRECTIVES} from 'ng2-bootstrap';
@Component({
selector: "side-bar",
directives: [TYPEAHEAD_DIRECTIVES, CORE_DIRECTIVES, FORM_DIRECTIVES],
template: `
<div class="searchArea" [ngClass]="{searchAreaForceLargeWidth: forceShowSearch}">
<form class="searchBlock" [ngClass]="{searchBlockForceShow: forceShowSearch}">
<div class="form-group">
<input [(ngModel)]="asyncSelected"
[typeahead]="getAsyncData(getContext())"
(typeaheadLoading)="changeTypeaheadLoading($event)"
(typeaheadNoResults)="changeTypeaheadNoResults($event)"
(typeaheadOnSelect)="typeaheadOnSelect($event)"
[typeaheadOptionsLimit]="7"
placeholder="Locations loaded with timeout"
class="form-control">
</div>
</form>
</div>
`,
})
export class SideBarComponent {
forceShowSearch = false;

上記のコードは基本的に ng2-bootstrap ページのサンプル ページと同じです。
結果が見えません。ページが「読み込み中」でスタックし、次の例外がスローされます。

そして、私は疑問に思っていました: これですべてですか? 多分私は何かを逃した？
