Edit3：此错误不会重复一般的“在开发人员确认的广泛使用的第三方库jide-common中存在一个错误，下面有一个链接。这个bug最近已经修复（在发布这个问题之后），许多旧版本的库仍然受到影响。因此，这些信息可能对其他开发者有用，他们偶然发现了同样的问题。Jidesoft DocumentPane中的java.lang.IndexOutOfBoundsException：索引：1，大小：1
我在使用Java进行GUI编程时遇到了问题。我不确定问题的具体来源（仍然无法弄清楚） - 可能是我的错误，jide组件中的错误代码，或者awt/swing焦点或事件处理错误。
以下代码取决于
- com.jidesoft：基德-网格：3.5.1
- com.jidesoft：基德-部件：3.5.1
- com.jidesoft：基德共用3.5.1
我发现＃2 this hint，但一些调试后，这似乎对我来说，每一个修改CellEditor的和其他组件EDT完成。
为了重现该错误，您应该运行此示例并打开包含CellEditor的选项卡（它必须是最后一行，否则不会发生索引溢出），然后在其中输入一些“不正确”的值，编辑器中，点击上一个选项卡上的关闭“x”按钮。之后，发生以下事件链：1）tab被关闭/移除，2）CellEditor验证器显示模式对话框，这又触发重新绘制选项卡3）由于缺少（关闭）选项卡，会抛出ArrayIndexOutOfBounds异常。

有添加了几分调试信息的 "extended" version of code。 我仍然无法找出问题的根源，不提及修复。提前致谢。
编辑：确定一两件事，我现在想通了，是展示从内部对话verify（）方法is wrong, according to docs：
的验证方法只存在判断输入是否有效它永不调出一个对话框或引起任何其他副作用。 shouldYieldFocus方法调用验证，如果值无效，则将其设置为最小值或最大值。 shouldYieldFocus方法被允许引起副作用...
因此，我将所有未实际验证的代码移至shouldYieldFocus（）。这并没有解决问题，但进一步拖延dialog.show（）与SwingUtilities.invokeLater（）似乎工作正常，没有陷阱......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
我进一步[简化了代码]（http://pastebin.com/4GqZixm7）。 不再使用DocumentPane，表格和单元格编辑器。在JideTabbedPane上只有一个简单的文本字段（如果验证失败，则显示模态对话框）。现在只使用oss库，所以任何人都可以运行这个例子。 但这个bug仍然存在于jide-oss-3.5.1中。 同样发生在jide-oss-3.6.16上。 –
