<h2>
FlexGridの検証
</h2>
<p>
検証に<b>CollectionView.getError</b>メソッドを使用すると、
<b>FlexGrid</b>はデータセルと行ヘッダーセルにエラーを表示します。
</p>
<p>
デフォルトでは、行ヘッダーセルにアイテム内のすべてのエラーが表示されます。
その動作をカスタマイズするには、 <b>getError</b>が特定のプロパティなしで呼び出されたときに
行ヘッダーに表示するエラーメッセージを返します（prop == null）。
</p>
<p>
無効な国または負の数を入力して、グリッドがエラーを識別し、無効なエントリがコミットされないようにする方法を確認してください。

<h2>
フォームの検証
</h2>
<p>
<b>CollectionView.getError</b>プロパティを使用してフォームを検証することもできます。HTML5検証APIの一部である<b>setCustomValidity</b>メソッドを使用して、関数を呼び出して適切な入力要素に結果を適用するだけです。
