Edit3：此錯誤不會重複一般的「在開發人員確認的廣泛使用的第三方庫jide-common中存在一個錯誤，下面有一個鏈接。這個bug最近已經修復（在發佈這個問題之後），許多舊版本的庫仍然受到影響。因此，這些信息可能對其他開發者有用，他們偶然發現了同樣的問題。Jidesoft DocumentPane中的java.lang.IndexOutOfBoundsException：索引：1，大小：1
我在使用Java進行GUI編程時遇到了問題。我不確定問題的具體來源（仍然無法弄清楚） - 可能是我的錯誤，jide組件中的錯誤代碼，或者awt/swing焦點或事件處理錯誤。
以下代碼取決於
- com.jidesoft：基德-網格：3.5.1
- com.jidesoft：基德-部件：3.5.1
- com.jidesoft：基德共用3.5.1
我發現＃2 this hint，但一些調試後，這似乎對我來說，每一個修改CellEditor的和其他組件EDT完成。
爲了重現該錯誤，您應該運行此示例並打開包含CellEditor的選項卡（它必須是最後一行，否則不會發生索引溢出），然後在其中輸入一些「不正確」的值，編輯器中，點擊上一個選項卡上的關閉「x」按鈕。之後，發生以下事件鏈：1）tab被關閉/移除，2）CellEditor驗證器顯示模式對話框，這又觸發重新繪製選項卡3）由於缺少（關閉）選項卡，會拋出ArrayIndexOutOfBounds異常。

有添加了幾分調試信息的 "extended" version of code。 我仍然無法找出問題的根源，不提及修復。提前致謝。
編輯：確定一兩件事，我現在想通了，是展示從內部對話verify（）方法is wrong, according to docs：
的驗證方法只存在判斷輸入是否有效它永不調出一個對話框或引起任何其他副作用。 shouldYieldFocus方法調用驗證，如果值無效，則將其設置爲最小值或最大值。 shouldYieldFocus方法被允許引起副作用...
因此，我將所有未實際驗證的代碼移至shouldYieldFocus（）。這並沒有解決問題，但進一步拖延dialog.show（）與SwingUtilities.invokeLater（）似乎工作正常，沒有陷阱......但。
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
我進一步[簡化了代碼]（http://pastebin.com/4GqZixm7）。 不再使用DocumentPane，表格和單元格編輯器。在JideTabbedPane上只有一個簡單的文本字段（如果驗證失敗，則顯示模態對話框）。現在只使用oss庫，所以任何人都可以運行這個例子。 但這個bug仍然存在於jide-oss-3.5.1中。 同樣發生在jide-oss-3.6.16上。 –
