Edit3：これは一般的な「私のコードでインデックスアウトバウンドセクションを持っています」という質問はありません。開発者によって確認された広く使用されているサードパーティのライブラリjide-commonのバグには、以下のリンクがあります。このバグは最近（この質問の公表後に）修正され、ライブラリの多くの古いバージョンがまだ影響を受けています。したがって、この情報は、jide-commonで同じ問題が発生した他の開発者にとっては役立ちます。java.lang.IndexOutOfBoundsException：Index：1、サイズ：1 in Jidesoft DocumentPane
私はJavaのGUIプログラミングに関する問題に直面しています。私は問題の特定の原因についてはまだわかっていません（それはまだ分かりません） - それは私のどこかのエラー、jideコンポーネントのいくつかの誤りのあるコード、awt/swingのフォーカスやイベントの処理に問題があるかもしれません。 JIDE-グリッド：3.5.1
次のコードは
- com.jidesoftに依存します：3.5.1
私はStackoverflowに見つかりましたが、いくつかのデバッグ後、CellEditorや他のコンポーネントに対するすべての変更がEDTで行われるようです。
バグを再現するには、この例を実行してCellEditorを含むタブを開いてください（最後の行にする必要があります。そうしないとインデックスのオーバーフローは発生しません）。エディタで、前のタブのいずれかで[x]ボタンをクリックします。その後、次の一連のイベントが発生します.1）タブが閉じられ/削除されます。2）CellEditorベリファイアがモーダルダイアログを表示し、タブペインの再描画をトリガーします。3）Missed（閉じた）タブによってArrayIndexOutOfBounds例外がスローされます。

追加情報をデバッグのビットと "extended" version of codeがあります。 私はまだ問題の原因を突き止めることさえできません。前もって感謝します。
編集：私は今で考え出し OK一つのことは、内からダイアログを表示することを確認することです（）メソッドis wrong, according to docs：
は方法を確認するには、入力が、それはいけ有効であるかどうかを判断するためにのみ存在しますダイアログボックスを表示したり、その他の副作用を引き起こしたりする可能性があります。 shouldYieldFocusメソッドはverifyを呼び出し、値が無効な場合は最小値または最大値に設定します。 shouldYieldFocusメソッドは副作用を引き起こすことができます...
私はshouldYieldFocus（）にすべての実際に確認するコードを移動しました。これで問題は解決されませんでしたが、dialog.show（）をSwingUtilities.invokeLater（）でさらに遅らせるとうまくいくように思えますが、まだ落とし穴はありません。
public CustomCellEditor(Class<?> aClass) {
super(aClass);
_textField.setInputVerifier(new InputVerifier() {
@Override
public boolean shouldYieldFocus(JComponent input) {
boolean inputOK = verify(input);
if (!inputOK) {
final ru.esc.erp.core.components.Dialog dialog = new ru.esc.erp.core.components.Dialog();
dialog.setTitle("Exception may be raised");
dialog.setContentPane(new JLabel("<html>Modal dialog opened with yet another delay.</html>"));
dialog.setLocationRelativeTo(null);
dialog.setModal(true); // false "fixes" the problem
dialog.setSize(new Dimension(300, 100));
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
dialog.setVisible(true);
}
});
}
return inputOK;
}
@Override
public boolean verify(JComponent input) {
return "777".equals(_textField.getText());
}
});
}
EDIT2：gif with captured video
私は[コードを簡略化]（http://pastebin.com/4GqZixm7）です。 DocumentPane、テーブル、およびセルエディタをもう使用しません。単純なテキストフィールド（検証が失敗した場合はモーダルダイアログを表示）をJideTabbedPaneに表示します。誰もこの例を実行できるように、今だけossライブラリを使用してください。 しかし、まだjide-oss-3.5.1のバグがあります。 jide-oss-3.6.16でも同じことが起こります。 –
