Strange behaviour whit custom JTextField and JToolTip

Question

Hello everyone. I hope I'm writing in the right section and sorry if I did not search for this issue but I really don't know which keywords I should use.
I'm using NetBeans 6.1 on WinXP and JDK 1.6.0_07, I have a custom JTextField with regex validation: when you type something that don't mach regex it shows a JToolTip. This JToolTip should disappear when the text typed is finally correct, or when the textfield loses focus (see code below).
import java.awt.Component;
import java.awt.Dimension;
import java.awt.Point;
import javax.swing.JToolTip;
import javax.swing.Popup;
import javax.swing.PopupFactory;
public class MyJTextField extends javax.swing.JTextField implements FormComponent
private static Popup popUpToolTip;
private static PopupFactory popUpFactory = PopupFactory.getSharedInstance();
private boolean isValidated = false;
private String regEx = "a regex";
public MyJTextField()
this.addKeyListener(new java.awt.event.KeyAdapter()
public void keyReleased(java.awt.event.KeyEvent evt)
if(evt.getKeyCode()!=java.awt.event.KeyEvent.VK_ENTER)
validateComponent();
else if(evt.getKeyCode()==java.awt.event.KeyEvent.VK_ENTER)
if(isValidated)
((Component)evt.getSource()).transferFocus();
this.addFocusListener(new java.awt.event.FocusAdapter()
public void focusLost(java.awt.event.FocusEvent evt)
if(popUpToolTip!=null){popUpToolTip.hide();}
public void validateComponent()
if(text.matches(regex))
isValidated = true;
if(popUpToolTip!=null){popUpToolTip.hide();}
else
isValidated = false;
if(popUpToolTip!=null){popUpToolTip.hide();}
String error = "C'è un errore nella validazione di questo campo";
JToolTip toolTip = createToolTip();
toolTip.setTipText(error);
popUpToolTip = null;
popUpToolTip = popUpFactory.getPopup(
this,
toolTip,
getLocationOnScreen().x,
getLocationOnScreen().y - this.getPreferredSize().height -1
popUpToolTip.show();
}(I've cut it a bit, here's only the lines that involve JToolTip use)
I have many of them in a form, and when the first tooltip appears (on the first textfield I type in) it never disappears, while nex textfields work just fine.It seems the first tooltip appearing can't be overwritten or something similar. If I use this same component on any other NetBeans project, everithing works without issues.
I have some other custom components working the same way (JComboBox, JXDatePicker), and they had this "not disappearing tooltip" issue since I changed this
popUpToolTip = popUpFactory.getPopup(this, toolTip, getLocationOnScreen().x, getLocationOnScreen().y - this.getPreferredSize().height -1);
whit this
popUpToolTip = popUpFactory.getPopup(null, toolTip, getLocationOnScreen().x, getLocationOnScreen().y - this.getPreferredSize().height -1);
but if I try it on the JTextField all textfield's tooltips stay stuck there, not only the first one appeared (while other components still works fine).
This thing is really driving me crazy. Someone has an hint (or a link to another thread) which could explain this strange behaviour?
Thanks in advance.

Note that an SSCCE wouldn't require you to post any proprietary code.Hmmm... well, I'll try again to reproduce the issue and post an SSCCE.

That probably indicates that the problem is somewhere other than where you're currently looking.Yes, I suppose so. Maybe it's some interference between all the custom components I created, or maybe something else that apparently doesn't conern at all. If I cannot reproduce it in an SSCCE and I'll figure out what's the cause of this mess I'll post it here for future knowledge.
Many thanks for your advices. :)
