I thought that the ActionPerformed() would fire an event if I changed the selection in a combo box, however fires even when the component is loaded.  What event do I use to fire only when  user makes a selection?

Thanks,
David

You should use actionPerformed()

I use a flag to skip the changes when loading

boolean skipChanges = false;


skipChanges = true;
// fill up the combobox and make initial selections
skipChanges = false;


public void actionPerformed(ActionEvent evt) {
   if (skipChanges) return;

   // do what you want
}

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Rather logical after a second thought, since loading the component = selecting the first item in it
