Action Event Doesn't Seem To Activate ActionListener

I have a frame showing some textfields and a couple of buttons, the classical "Ok" and "Reset" buttons, which are supposed to confirm the values of the textfields (closing the frame) and reset them respectively.

I think I thoroughly followed the "delegation method procedure" for managing event, that is , create the button object, define a listener class (implementing the ActionListener interface) , and add the listener class to the button using the "addActionListener" method . But there's no way to make the whole thing work.

No exception. Only when I click the button the "actionPerformed" method of the listener is simply ignored, as if it didn't exist.

Here is the code :

public FrameViewAddEstrazione (String ExtrPath) {
try
{
FilePath = ExtrPath;
F = new JFrame ();
PP = new JPanel();
PD = new JPanel(); // pannello data
