focus listener

[kajal sharma]

use the following code to validate a user data in textbox and if the data do not match with
database then got the focus back to field with a dialog box.
But When yearfield get lost focus by pressing tab key then dialog box come up but my ok
does not make any effect .It is there as it is .I think it is losing focus that's why it come
up.please rectify my problem.
public void focusGained(FocusEvent fe){}

public void focusLost(FocusEvent e){
Object source1=e.getSource();
System.out.println(source1==yearfield);
if(source1==yearfield){
aa=yearfield.getText().trim();
System.out.println(aa);
if (aa.equals("__/__/____")){
JOptionPane.showMessageDialog( this, "This is a
dialog" );
yearfield.requestFocus();
flag14=false;
a2=""; }

}
}

When I am only using focus listener than Caret is blinking one time in time field and one
time in yearfield.

please help java gurus.

Hello java gurus,
I tried this also but my focus is not returning on the same textfield why?
public void focusLost(FocusEvent e){
Object source1=e.getSource();
System.out.println(source1==yearfield);
if(source1==yearfield){
aa=yearfield.getText().trim();
System.out.println(aa);

if(e.isTemporary()){
yearfield.requestFocus();
return;}
else if (aa.equals("__/__/____"))
{

JOptionPane.showMessageDialog( this, "This is a dialog" );
flag14=false;
a2="";
}
}
}

Did you ever figure out a solution to this problem. I have had the exact same problem and no one seems to have provided a good solution.
Thanks

I had a similar problem with requestFocus not getting to a new frame. Here's what I was given as a workaround:

/*fix for bug in 1.2 that kept new frame from getting focus.
    May be fixed by now......     */
  public void paint(Graphics g)  {
      super.paint( g );
      while(!this.isVisible()) {
          try {
            Thread.sleep(100);
          }
          catch (InterruptedException e)  {}
      }
      entryField.requestFocus();
  }
