Question

In a class called HistoryPanel I have a static JTable called resultsTable with a static DefaultTableModel called tableModel. The table has a custom cell editor:

resultsTable.getColumn("Delete").setCellEditor(new DeleteButtonEditor(new JCheckBox()));

Inside, naturally, I override these two methods like this:

public Object getCellEditorValue()
{
    if (isPushed)
    {
        HistoryPanel.tableModel.removeRow(HistoryPanel.resultsTable.getSelectedRow());
    }
}

protected void fireEditingStopped()
{
    super.fireEditingStopped();
}

The exception is being thrown ONLY when I try to remove the last row of the resultsTable. When I’m removing a row that is not the last one it works perfectly. The exception is:

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 1 >= 1

And the line of code that causes the exception is:

super.fireEditingStopped();

Can anyone help me? How can I avoid this exception

Answer 1

Currently you remove the row you are editing during the edit operation. It would be a lot easier if you had posted an SSCCE so I could test my proposed solution, but now I will leave that up to you.

I assume that wrapping your

if (isPushed)
{
    HistoryPanel.tableModel.removeRow(HistoryPanel.resultsTable.getSelectedRow());
}

inside an EventQueue.invokeLater call might solve the issue. That way editing is finished when you remove the row.
