I added an InputVerifier to a column within a JTable. Print statements within
the method InputVerifier.verify() printed to the screen, but the cell that had
the InputVerifier attached was allowed to stop editing, and lost focus.

How to reproduce:

Run the following code. Select cell [0, 0] and type text other than "lala" into
it. When you hit return or click outside of the cell the first two print
  statements are printed to standard out. ("method verify()", "is textfield").
Select the cell again, and this time type the string "lala". Hit return or
click outside the cell. This time all three statements are printed, and false
is returned, but the cell loses focus.

class JTableExample extends JFrame
{
public JTableExample()
{
/* create a new JTable*/
JTable t = new JTable(2,3);
t.setValueAt("bing", 1, 1);

/* add an inputVerifier to the first column */
JTextField field = new JTextField();

field.setInputVerifier(new InputVerifier() {
public boolean verify(JComponent input) {
System.out.println("method verify()");

if (input instanceof JTextField) {
System.out.println("is textfield");
String text = ((JTextField)
input).getText();

if (text.equals("lala")) {
System.out.println("text is
lala");
return false;
}
}

return true;
}
});

t.getColumnModel().getColumn(0).setCellEditor(new
DefaultCellEditor(field));

getRootPane().getContentPane().add(t);

addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
dispose();
System.exit(0);
}
});
}

public static void main(String args[])
{
JTableExample mainFrame = new JTableExample();
mainFrame.setSize(400, 400);
mainFrame.setTitle("JTableExample");
mainFrame.setVisible(true);
}
}
